Accretion (a royai big bang longfic)
Fandom | Rating | Length: Fullmetal Alchemist | T | 155k COMPLETE
Summary:
accretion [ə-ˈkrē-shən] noun: An accidental deposit of “foreign” material that was not part of the painting process, f. ex. dried liquid residue, flyspecks, etc. (from Stella Art Conservation, LLC) Riza Hawkeye has worked as Security Director for private art authenticator Roy Mustang for eight years with little trouble. However, recently Mustang has taken on riskier and higher-stakes jobs, putting himself and his team in danger of exposure and harm. The objective of a new undercover job – authenticating an elusive ink drawing while undercover on a three-week island retreat – hits too close to home for Riza. Secrets carefully kept threaten to be brought to light, exacerbated by the closeness required while posing as a young engaged couple. Hold on, they have to pose as an… engaged couple? For three weeks?!
Vibes: Modern day Amestris AU, big ol' romcom, casual intimacy, what if instead of military alchemy it's dubiously legal art nerdery, everything BUT a heist, idiots to lovers, fake dating, FEELINGS, emotional support Hayate
The story includes gorgeous illustrations done by some extremely talented artists who have been working tirelessly for months. Go give them some love! You'll find pieces from @justanotherinterneruser, @chewytran, @areyousanta, and Crystal Capsids @rizaposting throughout Accretion, bringing it to life. You'll also find the work of @aldrendaux when you don't trip over sentences starting with the exact same word nearly as much as you would have otherwise ;-) If you need a kind beta with an eye for detail, you won't do better than Aldren.
Accretion is COMPLETE and posted in full on AO3!

Earth's Water
Where did all the water come from ? and which is oldest, the Sun or the water in our oceans ?
It may seem an odd question, after all, logic would suggest that the planet Earth isn't as old as the Sun which it formed around 4.55 billion years ago and the Sun started life around 4.6 billion years ago.
But, if you ask where did all the water come from, you'll understand the water we have in our oceans didn't necessarily originate here on Earth in the first instance.
So, let's start with what we do know. Space is full of hydrogen and helium gas, the stuff that powers our stars, but ever since the first star started to fuse these gasses, they have been busy pumping out more complex elements, oxygen, carbon, nitrogen .. and these have been combining to make water, Carbon dioxide, Methane and much much more.
Occasionally these clouds are brought together in regions, and gravity starts to pull them together into knots and strands.
Gravity continues it's work, pulling in material until it reaches a critical point where an inner core ignites and begins to fuse, and that fusion is what pushes back against the gravity, forming an equilibrium that will define what is the star and what is not. All the other material left behind spins rapidly around the new star, forming a disk and once again gravity starts to act and planets are created.
So where is water in this process ? The water was present right from the start, in the nebulous clouds that formed the star, both in terms of raw elements of hydrogen and oxygen, but also as water stuck on grains of dust and in some cases hydrogen and oxygen are bonded in different isotopes, creating heavy water.
So we know water existed before our Sun, but is that the same water in our oceans ?
Two main theories arise, either the water arrived on Earth through chemical inheritance, in that, the water was created externally, then made it's way to us as water, or it arrived as heavy water and then later down the line was converted back into water forming semi-heavy water.
Measuring the ratio between these two different types of water can tell us, and it wasn't until very recently that we've had the ability to measure this around stars forming.
Here on Earth, we find a mix of water, semi-heavy and not, but in space, in our own solar system, as comets and as ice on moons, we see mostly water, which is clearly chemical inheritance.
Observations of V883 Ori a newly forming star 1,300 light years from Earth provided an opportunity to measure this ratio as the system is forming.
And what they found was that V883 Ori held the same water mix as we see in outer space and in nebula, and a lower ratio of the semi-heavy water.
The conclusion is, the water in proto planetary disks is mostly normal water, and the process is indeed inheritance from that accretion disk, making most water in our solar system older than our own Sun !
But .. Earth has an odd mix, meaning it's almost certain that Earth also obtained water from multiple sources in it's early life, some of which was chemically altered into the water we see in our oceans along side the water that was delivered to us as our planet was born.
It doesn't answer how that water was delivered to our planet, by comets or by simple accretion at the start or accretion at a later date as gas we still sat in our birth nebula.
A MILLISECOND ROTATION PERIOD IS A RED FLAG
Recently, a paper I wrote about an accreting neutron star got accepted for publication in a scientific journal, and in the process of working on it, I was forced to think about something: how exactly should I interpret accreting neutron stars in the context of the galaxy of Antiocheka? (the fictional galaxy most of my astronomy cartoons/stories with the living celestial bodies are set in)
Black hole accretion is them eating the material; that is obvious. But when neutron stars accrete, they don't absorb the gas inside their bodies. It strikes and spreads across their surface. So an eating metaphor doesn't really work for them. I've seen some people compare accreting neutron stars to vampires, given they are "undead" stars and are sucking the plasma off of other stars. But since they don't absorb the star's "blood" they're not really like vampires. They're honestly more like the legend of Elizabeth Bathory, who bathed in the blood of her victims in order to look more youthful. Accretion increases the neutron stars' spin rates (which normally slow down due to their magnetic fields) and temperatures (which normally decrease due to cooling). The accretion therefore makes them seem more "youthful" in a way.
I have previously stated that the black holes of Antiocheka need to constantly accrete matter to remain conscious, which puts them in conflict with the stars, who are nuclear fusion powered. I don't imagine the neutron stars have it quite so dire. But Antiochekan star society uses an energy currency, and so as a neutron star loses its magnetic field, temperature, and rotation, they start running out of ways to generate energy and maintain their status in stellar society. In that case, maybe it's not surprising some would turn to more brutal methods of generating energy...stripping material from other stars...

This is my first ever retrowave-inspired song, and I’m planning to do a full album in this style. If you like this, I’d really appreciate if you’d go over and give me a like and/or subscribe on YouTube to help me out getting this into more ears. I’m trash at promoting myself, lol.

Accretion, chapter 5
Accretion is a story that follows the rise and fall of Galactic Boss Cyrus and the fate of Team Galactic and the lives of those affected by it after its reformation under Saturn.
This is gonna be a sad one. I hope you all enjoy it.

Protostar in LDN 1527 by Judy Schmidt Via Flickr: Update: Simeon Schmauß over on Twitter (@stim3on) recommended G'MIC for taking care of the horizontal noise / banding. It worked pretty great. There's a Photoshop plugin for it, too. Wanted to process my own version of this one, since nebular landscapes are some of my favorite views. Having a hard time with the linear noise pattern, especially near the top of the image. In the center of this view is a newly forming star crossed by a dark disk of dust (say that three times fast!) which is casting shadows to the left and right, and allowing cones of light out the top and bottom. Think of it like a light bulb inside of a donut with a bunch of fog. Though the infrared light can penetrate much of the dust, there are clues in the image that show some of the dust is still too thick to see through. At the lower right especially are a lot of background galaxies. On the left, the background galaxies are fewer, and what we see are dimmer, so we can tell there is more dust there. You can see the official release here. They've got a much better description than I could ever write.
