Title: The Role of Outflows, Radiation Pressure, and Magnetic Fields in Massive Star Formation
Authors: Anna Rosen and Mark Krumholz
First Author’s Institution: Center for Astrophysics | Harvard & Smithsonian
Status: Accepted to ApJ
This newly formed star at the heart of the Orion Nebula is blowing a bubble that’s preventing further star formation around it. [NASA/SOFIA/Pabst et al.]Stellar physics is a broad field that touches on a range of phenomena from magnetic fields to radiative processes and thermonuclear fusion to plasmas. Stars form through the gravitational collapse of cold, dense, dusty protostellar cores, themselves embedded in thick molecular clouds or filaments. Massive stars, defined as those with a mass greater than 8 solar masses, are of key interest in star formation. Although they are extremely rare, comprising less than 1% of the total stellar population, they make their presence known by dominating the surrounding interstellar medium (ISM) with their powerful stellar ...
