Violent star formation : from 30 Doradus to QSOs : proceedings of the first IAC-RGO meeting, held in Puerto Naos La Palma, Spain, November 8-12, 1993

This volume deals with the most recent theories of violent star formation. It covers the formation and evolution of new stellar clusters, and explores all the possible consequences in a wide variety of objects where massive stellar bursts have occurred. It thus presents an alternative model to that which suggests supermassive black holes are the power houses of active glactic nuclei. In addition, it analyzes the impact of Wolf-Rayet stars, stellar winds and supernovae on their host galaxy, and provides evidence of massive superassociations and of supersonic velocity dispersions that result from photo-ionization by violent star formation. This book gives a valuable overview and a timely update on all aspects of violent star formation for graduate students and researchers in the field.
