Maggiori informazioni sul libro

The book explores the formation of high-mass stars through innovative radiation-hydrodynamic simulations, detailing the gravitational collapse of massive molecular clouds and the development of surrounding accretion disks. It reveals how intense UV radiation interacts with infalling material, demonstrating that ionization feedback does not hinder protostellar mass growth or fragmentation. Additionally, it provides a comprehensive understanding of H II regions, addressing their morphology, time variability, and age, effectively resolving the long-standing lifetime problem in astrophysics.
