L'exoplaneta més pròxim, Barnard b

L’exoplaneta més pròxim a la Terra, Barnard b Per I. Ribas, Veure original a la revista nature 14º

Durant dècades, els astrònoms han buscat planetes al voltant d’una estrella propera coneguda com l’Estel de Barnard. Barnard b es l’exoplaneta més pròxim a la Terra

Els planetes de les estrelles que no són el Sol són coneguts com a exoplanetes. Són extremadament febles en comparació amb les seves estrelles amfitriones, i les seves òrbites normalment són massa petites per trobar-les – fins i tot utilitzant els telescopis més grans disponibles avui-. Com a resultat, les últimes tècniques d’imatge d’alta resolució estan limitades als planetes gegants en òrbites àmplies al voltant d’estels.

La major part del que es coneix actualment de les propietats, la formació i l’evolució dels exoplanetes prové, doncs, de mètodes indirectes que mesuren variacions en la llum rebuda a la Terra des de les estrelles amfitriones. Un dels mètodes més fructífers, utilitzats per Ribas i col·legues, és la tècnica de velocitat radial. Implica mesurar els canvis en la velocitat d’una estrella amfitriona al llarg de la línia de visió d’un observador, i és sensible a la massa de l’exoplaneta. No obstant això, perquè les mesures depenen d’un valor desconegut (la inclinació de l’òrbita del planeta), la tècnica només proporciona un límit inferior a la massa del planeta.

Utilitzar el mètode de velocitat radial per detectar planetes en òrbites de llarg termini és difícil, ja que com més gran és la distància orbital, menor serà el senyal planetari. El mètode de trànsit, que mesura la caiguda de la brillantor quan un planeta passa per davant de la seva estrella amfitriona, també és ineficaç per als planetes en òrbites de llarg termini. Aquesta limitació ha restringit la detecció i la caracterització d’exoplanetes principalment a companys estrets, especialment en el cas dels planetes de massa baixa, els senyals són petits.

Barnard b, batejat així en honor a la seva amfitriona, triga uns 233 dies a orbitar a la seva estrella i, encara que està relativament a prop seu (a un 40% de distància del que està la Terra del Sol), és un món fred i fosc que podria estar a uns -170 graus centígrads. “És un món gelat perquè rep molt poca energia de la seva estrella: només un 2% del que la Terra obté del Sol”, i es troba a prop de l’anomenada ‘línia de gel’, una zona orbital al voltant d’una estrella en la qual compostos volàtils com l’aigua poden condensar-se en gel sòlid. Per això, és “molt improbable” que Barnard b tingui aigua líquida a la superfície, però no es pot descartar que la tingui al subsòl.

The “Sónar Calling” message includes 33 music pieces of 10 seconds each, commissioned exclusively from artists from diverse backgrounds and origins who encapsulate Sónar’s exploratory approach to music over its quarter century of existence.

The first batch of transmissions sent on 16.17.18 October of the current year have included music from Autechre, Modeselektor,Laurent Garnier, Holly Herndon, Matmos, Jean-Michel Jarre, Nina Kraviz, Francisco López, The Black Madonna, Kerri Chandler,Ólafur Arnalds, Kode 9, Laurel Halo, Soichi Terada, Fatima Al Qadiri, Cabo San Roque, BFlecha and Nisennenmondai.

A second batch of transmissions is planned for April 2018 when music from Richie Hawtin, Carsten Nicolai, Squarepusher, Kate Tempest, Daito Manabe, Juana Molina, Niño de Elche, Cora Novoa, Lorenzo Senni,  Zora Jones, Desert, LCC, Yuzo Koshiro and more will be sent.

All of them have performed at Sónar on one or more occasions and some of them will also be included in the line-up for Sónar 2018. Look out for the first announcement in the coming weeks.

“Sónar Calling GJ273b” is also a collective celebration in which the Sónar audience can take part, participating in the open call which kicks off today. The public is invited to send an original composition, in any genre or musical style, and conceived with an unknown, extraterrestrial audience in mind. From all the pieces received, Sónar will select 3 to form part of the next transmission, programmed for April 2018. The selected creators will be invited to celebrate with Sónar in Barcelona next June together with a 4 guests (4 VIP passes).

Luyten’s Star is in the constellation Canis Minoris, at a distance of 12.4 light years from us. It is a cool red dwarf star, with a temperature of about 3000ºC (compared to 5500ºC of the Sun) and a mass one third that of the Sun. The star, which cannot be seen without a telescope, was named after a Dutch-American astronomer, Willem Jacob Luyten, who measured its motion across the sky.

The discovery of two exoplanets around this star was announced in early 2017. One of them, named Luyten’s Star b or GJ273b, has a mass about three times larger than Earth and is located in the habitable zone of the star, although it is probably somewhat warmer than our planet. Its year lasts about 19 of our days.

It’s not known if Luyten’s Star b does indeed have liquid water, nor if it has retained an atmosphere. But at the moment there is no reason to think that it is not habitable. If it were, it would be a world with oceans like ours with a sky lit by a star apparently larger than the sun and shining with a reddish light.

The first transmissions were sent on the eve of Sónar’s 25thanniversary, from the EISCAT antenna in Tromsø, Norway on October 16, 17, and 18, 2017.

Sónar Calling’s message was transmitted on three successive days, providing an opportunity for possible “astronomers” from out of space observing Earth from Luyten’s Star to confirm that the signal is from another civilization.

The first message contained a mathematical and scientific tutorial created by METI (Messaging to Extra-Terrestrial Intelligence) that starts with basic principles and builds up, step by step, to more complex concepts. The message describes key characteristics of electromagnetic waves by “pointing” to the frequency and duration of the radio waves themselves. By making a direct link between the form of the radio signal and scientific content that is encoded, additional clues are provided to help any extraterrestrials interpret the message accurately. Unlike past radio messages that relied on pictures, METI’s tutorial is designed to be understandable by extraterrestrials in a mathematical and conceptual way.

The tutorial was sent in binary code at two frequencies near 930 MHz, using the 32-meter, fully steerable parabolic antenna of the EISCAT, which has a peak power of 1.5 MW. The tutorial was sent three continuously times on each of three days at a speed of 62.5 to 500 bits per second, followed by the musical pieces that have been sent at to 500 bits per second for a total transmission time of 2.5 hours. By repeating the message each day, possible extraterrestrial recipients will be able to correct errors that occur as the messages travel over 70 trillion miles between Earth and Luyten’s Star. 

In April 2018, during the second phase of “Sónar Calling GJ273b”,  we will send an expanded tutorial to the same star. It is expected that this follow-up transmission will turn the EISCAT antenna into a musical instrument, transmitting pulses at several different frequencies, mimicking the tones of a musical scale. By sending basic melodies at multiple radio frequencies, Sónar Calling will expand the METI tutorial to describe the physics and psychology of music perception. This second round of transmissions will end with a clock time marking the date that humanity will be listening for a reply 25 years from now.

I'm on the train back from this year's International Enterprise Educators Conference (IEEC) as inspired, challenged, and intimidated by the practice of my peers as ever.

One persistent theme this year for me was the continued pursuit of ever more authentic educational delivery, assessment, and contextualisation. One student was absolutely convinced this should start from day one year one and I found this a bit challenging if I'm honest. The student seemed to equate authenticity with industry briefs, client work, and similar - and delivered from the first day of study.

Authenticity is important; it's attractive to students, parents, and employers as a potential head-start for graduate employment, it gives content more credibility and legitimacy, and it creates opportunities for industry to play a role in the educational pathway that might lead someone to their door in the future looking for a job.

But how authentic can we or should we make it? In practice the logistics and (time) costs of simulation and engaging industry can be prohibitive (as setting up degree apprenticeships is proving), and in principle we are still in education... If students actually wanted *authentic* they should have gone straight to the workplace!  

Now direct entry to the workplace might not be an available option (rightly or wrongly), or it might not have been perceived by the student as an option (HE and FE marketing to school-leavers rather squeezes out the 'go direct' route) but equally there must be some value to 'less than authentic' education as some sort of stepping stone BEFORE the actual workplace... As a safe space, as a test, as a general or fundamental grounding in something before indulging in specific practice? 

Some students will seek out this stepping stone, others will see it as the only available route, others will see it as a way to keep their options slightly open whilst they explore.

The question emerging here is 'what constitutes authenticity?' (and the answer may be different for starting student, finishing student, educator and employer). How 'real' does it need to be?

More authentic experiences feel more satisfying and more relevant than classroom learning, but do we have any evidence they're better at preparing students for the world of work (in general)? Does learning on the job accelerate learning or confine it to specific tasks and organisations? Does classroom-based learning help cultivate a broader and more critical approach or waste time that could be spent practising a specific process? I suspect the best option is a mix, the fundamentals leading to the specific and practical, or better still an early authentic experience which helps contextualise and make relevant the fundamentals which are then taught before practical content is returned to.

Does this mean deliberately NOT adding too much authenticity too soon? Or maybe there are specific features within authenticity that can be drip-fed into a programme? You might not let first-year students work to real live client briefs for example, but still use industry examples and have an industry judge for the assessment. You might save complex collaborative projects for later stages after skills and confidence have been built up via simpler but no less collaborative initial projects.
