The review papers in this volume provide an in-depth examination of complex astrophysical phenomena of star formation via multi-wavelength observations and modeling. Among the fundamental issues discussed in the book are: The role of gravity and magnetized turbulence in the formation and evolution of molecular clouds The stellar feedback (supernovae, HII regions, winds, cosmic rays) in regulating star formation The origin of the stellar initial mass function and its universality across various environments Jets, magnetic fields and high energy particles in stellar clusters The origin of the first stars and black holes The goal of these papers is to review the major processes governing star formation and to investigate how they are interlinked. In doing so, they provide an in-depth look at the tremendous theoretical and observational progress that has been made in the recent past and also outline future perspectives. Previously published in Space Science Reviews in the Topical Collection "Star Formation"

The cataclysmic stellar explosion Supernova 1987A, visible to the naked eye, was the nearest and brightest supernova witnessed since the invention of the telescope four centuries ago. This volume deals with supernovae and their remnants, in terms of exceptional phenomena that produce and release high-energy nuclei and particles. Marking the thirtieth anniversary of SN 1987A, the proceedings of IAU Symposium 331 introduce the accumulating knowledge on these central sources in many active fields of investigation: stellar evolution and the diversity of supernova progenitors and their properties, explosive nucleosynthesis and particle acceleration in the most extreme environments known to physics, and the long-standing issues about the origins of heavy nuclei in the Universe and of cosmic rays. Through its interdisciplinary approach, this volume also sheds light on the open issues related to these topics and emphasizes topics of future interest with upcoming multi-wavelength and multi-messenger facilities.
