#blue straggler

Obsessed with Raif... alil bit. Ngl. And actually Yren 😭 and stupid bloody Kav. Ugh 😒😒😒

Judge myself for that last one lol

But just a random question I've only done LI routes and not a non LI one.

The weirdos (blue weirdo and silver weirdo) that spy on us aren't romanceable, right??

They are just weirdos??? 🤔🤔🤔

😊😊

No reason to judge yourself for liking Kav. He's very lovable. 🙂‍↕️ He thinks so, anyway!

As for Blue and Silver.

I mean, they are weirdos. Rofl. That is true. They aren't romanceable, but there are endings where you can choose to leave the crew and go with them later on (mostly in Chapter 10 but there is one in Chapter 8 too).

Bluey gets a slightly extended ending scenario (in Ch 10) where some sort of vague...tension is there. Maybe not romantic. But maybe not...not romantic.

But because MC doesn't get to know him well in-game, it's mostly just implication.

This globular cluster is one of the most dense areas in our galaxy, the core of has collapsed, forcing stars so tightly together that they are forming binary partners and even merging together in a process known as blue stragglers.

The Jellyfish cluster is 12.9 billion years old, and most of the stars left in it are red dwarfs, small k and g type stars like our own Sun, and so this core collapse merger creates a more blue like colour towards the centre region.

It's also noted that the mass density quickly tapers off to the outer edges, and like some other globular clusters, may be because it has passed through the galaxy near the galactic core which has pulled may of the starts outwards and even lost to the core itself.

The open cluster without a NGC number !

Whilst Messier included it in his catalogue of not quite comets, Sir John Herschel didn't include it in his, which ultimately became NGC objects.

And that's probably because it's a cluster of stars set against the Milky Way behind it, the image above with it's blue tint reveals the actual stars in the cluster, while observations with binoculars don't.

Blink and you'll just not see an open cluster here, yet there is signs of nebulosity and some interesting stars, including a red giant in a binary partnership.

The whole cluster is thought to be around 67 million years old and around 2,000 light years from Earth.

It's also suggested some of the blue stars are blue stragglers, stars that have merged due to their proximity and gravity, and turned blue in the process.

Constellation of Fornax

Fornax (The Furnace in Latin) is a small Southern hemisphere constellation, which while on the face of it looks like just 2 stars, actually punches way above it's diminutive size.

Stars

The brightest Star Alpha Fornacis is a fascinating system, made up of a binary pair, an aging F type star, having just finished it's main sequence (α For A), and the companion (α For B) a G type star in the main sequence but with very peculiar past.

The system is 46 light years from our Sun, and has a high proper motion, meaning it's orbiting our galaxy in a significantly different way to the local group of stars.

350,000 years ago, it came within .2 light years of the star Nu Horologii, both systems show large debris fields and would have impacted on each other. In the Solar system's history, similar close calls have pushed oort objects inwards, and there is speculation that such close calls can lead to a significant transfer of objects between systems.

Back to α For B, the star shows signs of being what is referred to as a blue straggler, an outlier of the standard HR stellar evolution, and common in the confines of particular blue giant clusters. However, the system is showing an age of around 2 billion years, and blue stragglers like blue giants generally rarely make it past a few 100 million years.

Astronomers believe that this star has cheated death by accreting matter or merging with a companion star early on, and still remains in the main sequence to this day.

The second star β For is a red clump evolving star, similar to α For A, entering it's helium fusing red giant stage.

Deep Space Objects

Fornax has not just a few galaxies, but an entire cluster named after it. The Fornax cluster of galaxies lies around 62 million light years from the Milky Way, comprising of a beautiful array of different galaxies, with NGC 1399 at its core.

Like all massive elliptical galaxies, they lack star formation, so very little in the way of dust and gas lanes, or clusters of bright new blue giant stars, in fact, almost all the stars here are aging old stars, probably around the same age as our own Sun, hence the more yellowish colour of the object.

It has at the centre a supermassive blackhole, over 100 times the size of the Milky Way, at around 500 million solar masses.

So, I’ve been working on an antagonist for a story based off stellar phenomena. Namely, a vampire based on the concept of blue stragglers, or older stars that theoretically siphon hydrogen from their neighbors, thus remaining hotter and brighter while the surrounding stars grow comparatively dimmer and cooler.

I’ve had several names in mind. Gorlois/Gorlassar, Ara (after a constellation that features a globular cluster with several blue stragglers,) or Algol, after the algol variable (a class of binary star where mass has apparently been exchanged between the two components.)

Major Result in Stellar Evolution

Nebula. Collapse. Protostar. Main Sequence. Red Giant. Planetary Nebula. White Dwarf.  This is the cycle of life for a star like our Sun.  By observing stars across the galaxy, we see snapshots of different points in a star’s life cycle.  It’s the same with people; If you went for a walk in a city and observed people for a day, you would see every single stage of a person’s life: Infant, child,…

The Hubble Space Telescope has found a rare class of oddball stars called blue stragglers, the first time such objects have been detected within our galaxy's bulge.

Blue stragglers — so named because they seem to be lagging behind in their rate of aging compared with the population from which they formed — were first found inside ancient globular star clusters half a century ago.
