Thanks Helio, I'm not a specialist, reason I'm on this forum...to try to understand With the example I tell in my question, the molecular cloud collapse. If it collapse the number of particles remaining the same, as the radius will decrease therefore the volume as well giving that the density of...

Good morning, I'm trying to understand the collapse and fragmentation of a molecular cloud leading to a proto=star. I read about the Jeans law .and now about the Bonnar Ebert model. As an example I took a molecular cloud of 10^4 solar mass, a temperature of 10K, 1000 particles by cm^3 (taking a...

Hello, I'm Philippe, a Belgian retired in China (I'm 72) and I'm staring to learn about the stars formation. For the moment I'm busy to try to understand the collapse and fragmentation of molecular cloud, the Jeans law and it's application Have a nice day
