Constraining the Stellar Mass Function in the Galactic Center via Mass Loss from Stellar Collisions [PDF]
Advances in Astronomy, 2011 The dense concentration of stars and high-velocity dispersions in the Galactic center imply that stellar collisions frequently occur. Stellar collisions could therefore result in significant mass loss rates.

Stellar Streams Reveal the Mass Loss of Globular Clusters
The Astrophysical Journal LettersGlobular cluster (GC) streams, debris of stars tidally stripped from their progenitor GCs, have densities that correlate positively with the GC mass-loss rate.

The Astrophysical Journal, 2023 Eta Carinae ( η Car) exhibits a unique set of P Cygni profiles with both broad and narrow components. Over many decades, the spectrum has changed—there has been an increase in observed continuum fluxes and a decrease in Fe ii and H i emission-line ...

Stellar coronal mass ejections [PDF]
Serbian Astronomical Journal, 2022 Stellar coronal mass ejections (CMEs) are a growing research field, especially during the past decade. The large number of so far detected exoplanets raises the open question for the CME activity of stars, as CMEs may strongly affect ...

Radio observations of stellar mass loss [PDF]
Symposium - International Astronomical Union, 1979 A program to search for steady-state thermal emissions from stars has been in progress for several years in Canada (Purton 1976). In this program we have specifically excluded flaring objects (such as β Lyr or HR1099) where non-thermal emission is probably responsible.

The Astrophysical Journal, 2023 Stellar coronal mass ejections (CMEs) have recently received much attention for their impacts on exoplanets and stellar evolution. Detecting prominence eruptions, the initial phase of CMEs, as the blueshifted excess component of Balmer lines is a ...

Critical Rates of Stellar Mass Loss [PDF]
Symposium - International Astronomical Union, 1979 Many of the effects of mass loss on OB stars have now been explored. Mass loss will cause a star to be overluminous for its mass (though less luminous than a star of its original mass) and, for moderate mass-loss rates, the luminosity decreases at the same rate as the mass contained in the convective core decreases causing the main sequence lifetime to

Mass loss in 2D rotating stellar models [PDF]
Proceedings of the International Astronomical Union, 2010 AbstractRadiatively driven mass loss is an important factor in the evolution of massive stars. The mass loss rates depend on a number of stellar parameters, including the effective temperature and luminosity. Massive stars are also often rapidly rotating, which affects their structure and evolution.

Stellar mass loss and galactic chemical evolution [PDF]
International Astronomical Union Colloquium, 1981 We summarize here some of the results that we have obtained from chemical evolution models. In particular, we discuss those aspects related to stellar mass loss, helium production, a varying heavy element yield and the very light stars.The observed value of the helium to heavy element abundance ratio ΔY/ΔZ is about 3 (e.g. Lequeux et al. 1979).
