In that sense, it also affects planet formation, and if those planets can be anything like Earth. The turbulence in the ISM not only determines star formation rates it determines the types of stars that form. The study is published in Nature Astronomy. Their paper is titled “ The sonic scale revealed by the world’s largest supersonic turbulence simulation.” The first author is Christoph Federrath, a Professor at the Institute for Theoretical Astrophysics (ITA) at the Center for Astronomy of the University of Heidelberg. The authors of the new study wanted to understand it better, and they performed the most high-resolution supercomputer simulations yet of that turbulence. A new study presents a gas simulation of the ISM and how it forms molecular clouds. Turbulence plays a central role in all of this. This back and forth between stars and the ISM determines a galaxy’s star formation rate and its star formation lifespan. After stars form, they eventually give the material back to the ISM via supernovae, planetary nebulae, and stellar winds. The ISM has a complex relationship with stars. Scientists have questions about the role that turbulence plays in that fragmentation and how it affects the types of stars that eventually form. Star formation begins when the ISM fragments into enormous clouds of gas called molecular clouds, which are the precursors to stars. The ISM is the matter and energy between solar systems in a galaxy.
