A Few Tens au Scale Physical and Chemical Structures Around Young Low-Mass Protostars

A Few Tens au Scale Physical and Chemical Structures Around Young Low-Mass Protostars by Yoko Oya
English | EPUB (True) | 2022 | 219 Pages | ISBN : 9811917078 | 116.3 MB

This book characterizes the kinematic and chemical structures of disk-forming regions around low-mass protostellar sources and their interplay based on Atacama Large Millimeter/submillimeter Array (ALMA) observations. It describes the chemical evolution of molecules formed in an interstellar gas using the ALMA observations of 5 Sun-like protostars at a spatial resolution of a few tens au scale, which unveils the physical mechanism of star and planetary formation.

Millimeter and Submillimeter Studies on the Active Trinity of Gas, Stars, and Black Holes in Seyfert Galaxies By Takuma Izumi

This thesis focuses on understanding the growth and formation mechanism of supermassive black holes (SMBHs), an issue it addresses by investigating the dense interstellar medium that is assumed to be a crucial component of the fuel for SMBHs. The thesis also offers unique guidance on using the Atacama Large Millimeter/submillimeter Array (ALMA) in active galactic nuclei (AGN) research.
