Astronomy / Space You'll Never Look at Nebulae or Binaries Stars the Same Way Again

The video starts off with a spherical Bok Globule (a dark nebula of "dense" hydrogen and dust). The interesting bit starts at t=30s, when the first star formation and unstable binaries begin forming, and they start whipping each other around. It's easy to see why binary stars are so common. But it's a bit harder to see how they become stable enough to form complex higher multiplicities.

Please forgive my spelling and grammar, I am running on fumes after a 20kly 1 day slog. :)

Amazing stuff as usual Ziljan...fascinating to watch! Seeing the stars get flung off, seeing the joining, splitting and rejoining...the chaos of early systems is intense!

A very impressive simulation!
Now someone needs to model the effects of some of that gas being stripped away as the most massive stars go supernova, which will prevent those knots from acquiring more mass but also trigger the collapse of other clouds away from the heart of the cluster. (It's probably already being done). It was quite a surprise to see how much the early star systems appeared to interact with each other - these did not look to be forming 'in isolation' as models of our own solar system generally assume.
It does remind me to be impressed that the Stellar Forge is trying to pack a lot of physics in to create the star systems we find in Elite Dangerous: Horizons - and that it has to do this every time you open the System View!

Ziljan-man I love your posts. Why can I give you only one rep? I found the video fascinating, thank you for sharing it with us. [heart][up][heart]


Slightly related note: Are there any Hergig-Haro objects in this game? I have been looking for them near the dark nebulae I have explored, but I have not seen any.

That would be awesome, a complete simulation history from Bok Gobule to open cluster. This video is very early in the formation process only to 0.26 Myrs. Stars wouldn't have time to go super nova yet. And yes, it was pretty shocking to me how strongly these systems were interacting in the early part of formation. We have to remember that the "isolation" models reflect our limited time scales of observation and are influenced by our understanding of how our single solar system formed, which was thought to be quite late in our parent nebula's history, possibly after sibling stars had time to go nova.

Unfortunately, ED doesn't model accretion disks or polar ejection streams (yet!), so we wouldn't see any HH objects that result from supersonic jets colliding with nebula. But in ED, the star forming nebulae are so bright, the whole thing is like an HH object :)
