Stellar Evolution in Early Phases of Gravitational Contraction

Publications of the Astronomical Society of Japan, 1961
Abstract The surface condition for red giant stars worked out in the previous paper indicates that stars lie in the low luminosity and low temperature region of the H-R diagram cannot be in equilibrium so that the evolutional path of contracting stars in this region will be different from that calculated by HENYEY et al. The age of these

Episodic Phenomena in Early Stellar Evolution

1991
The outbursts of FU Orionis objects axe apparently caused by a rapid increase in mass accretion through a protostellar disk onto a T Tauri star. Accretion rates during outbursts are very large, ≳ 10−-4 M*yr−1. Event statistics indicate that many, if not most, low-mass stars undergo multiple Fuor events, ultimately accreting at least 5% to 10% of the ...

New perspectives on the formation and early evolution of stellar clusters

We present a collection of works which use and build upon the coupled magnetohydrodynamical, N-body dynamics, and stellar evolution framework Torch. First, we investigate the effects of early-forming massive stars on the star cluster formation and assembly processes.

Depicting the Early Evolution of Globular Clusters Through the Lens of Multiple Stellar Populations

2014
A major paradigm shift has recently revolutionized the classical picture depicting globular star clusters (GC) as simple systems of coeval stars born out of homogeneous material. Indeed, detailed spectroscopic studies of GC long-lived low-mass stars performed with 8–10 m class telescopes, together with high-precision photometry of Galactic GCs obtained
