Pressure-regulated, feedback-modulated star formation in disk galaxies

EC Ostriker, CG Kim - The Astrophysical Journal, 2022‏ - iopscience.iop.org
The star formation rate (SFR) in galactic disks depends on both the quantity of the available
interstellar medium (ISM) gas and its physical state. Conversely, the ISM's physical state …

Momentum injection by supernovae in the interstellar medium

CG Kim, EC Ostriker - The Astrophysical Journal, 2015‏ - iopscience.iop.org

Formation of molecular clouds and global conditions for star formation

CL Dobbs, MR Krumholz… - … and Planets VI, 2014‏ - books.google.com
Giant molecular clouds (GMCs) are the primary reservoirs of cold, star-forming molecular
gas in the Milky Way and similar galaxies, and thus any understanding of star formation must …

Star formation in disk galaxies. I. Formation and evolution of giant molecular clouds via gravitational instability and cloud collisions
