Star formation by collapse of molecular clouds

Показать описание

The calculation models the collapse and fragmentation of a molecular cloud with a mass 50 times that of our Sun. The cloud is initially 1.2 light-years (9.5 million million kilometres) in diameter, with a temperature of 10 Kelvin (-263 degrees Celsius).

Wow that zooming makes me realize how much resolution that simulation has.

I think you misunderstand what the 3-body problem is about. A 3-body problem implies 3 objects that strongly affect each other's orbits. It also discusses how, because of chaos theory, we cannot accurately predict the locations of those objects at a given time in the future.

The solar system is much more stable than the typical 3-body problem, but even then we cannot accurately predict the planet's locations far in the future. This is why ephemerids are always updated.

wow, that's amazing, do we know if such clouds are a result of death of several stars (or just one huge) or if it's a residue from the big bang?

this is really awesome!! wonder how long it took to calculations and everything!

So there's like a single gas vortex producing stars and flinging them around? Is this how it works in reality?

Can I use this for a presentation by any chance?

only if the mass is neglegable relative to the 2 main bodies. Besides, I think in this instance we are talking about many more than 3 bodies and each with significant mass relative to each other.

Great time lapse photography, BEAUTIFUL!!!

Thats really awesome! no wonder there are so many billions of stars :)

Can I obtain this software somewhere online? Also, what was the render time for this simulation?

@WZW1982 a 3-body system is mathmaticaly impossible to balance and therefore any motion from any of the bodies within it inherantly causes chaos

Интересное моделирование. Довольно много протопланет улетело вникуда, наружу.

Did you also have troubles figuring out if the Dinosaurs were real or not in Jurassic Park?

ok. I have a question. Why our solar system is so stable?

3-body gravitational systems by definition cant achieve equilibrium. Yet we can observe this equilibrium just by looking at our own solar system.

So where this observable equilibrium according to this video's model\theory\simulation comes from?

thanks

@WZW1982 then what are those irregularities you are talking about? thanks . argument "they will remain that way for eons" is not really an argument tho. peace

@kobasica

Are you suggesting that anything that takes longer than a few hundred years to happen is impossible to happen?

would it be fair to say that main sequence stars only not pre or post, are in color from lowest to highest the following : red, orange, yellow, white, blue-white, and blue being the hottest ? are there any other colors of main seq. stars ? any input would be appreciated thanks

NASA’s APOD 2017-10-08 _(»Dark Molecular Cloud Barnard 68«)_ sent me here. Cheers!

Man, I really love this but now it has me wondering on the evolution of planets as stars die, and more generations form. Could it be that some planets formed many generations ago and have morphed over many new star births?
