Mass loss and stellar superwinds [PDF]

open access: yesPhilosophical Transactions Series A, Mathematical, Physical, and Engineering Sciences, 2017
Mass loss bridges the gap between massive stars and supernovae (SNe) in two major ways: (i) theoretically, it is the amount of mass lost that determines the mass of the star prior to explosion and (ii) observations of the circumstellar material around SNe may teach us the type of progenitor that made the SN.

Mass loss in 2D rotating stellar models [PDF]

open access: yesProceedings 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.

Constraining the Stellar Mass Function in the Galactic Center via Mass Loss from Stellar Collisions [PDF]

open access: yesAdvances 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.

The Dynamical Evolution of Globular Clusters with Stellar Mass Loss [PDF]

open access: yesJournal of Astronomy and Space Sciences, 1991
The dynamical evolution of globular clusters is studied using the orbit-averaged multicomponent Fokker-Planck equation. The original code developed by Cohn(1980) is modified to include the effect of stellar evolutions.

Stellar Streams Reveal the Mass Loss of Globular Clusters

open access: yesThe Astrophysical Journal Letters
Globular cluster (GC) streams, debris of stars tidally stripped from their progenitor GCs, have densities that correlate positively with the GC mass-loss rate.

The Long-term Spectral Changes of Eta Carinae: Are they Caused by a Dissipating Occulter as Indicated by cmfgen Models?

open access: yesThe 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 ...

Radio observations of stellar mass loss [PDF]

open access: yesSymposium - 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.

Detection of a High-velocity Prominence Eruption Leading to a CME Associated with a Superflare on the RS CVn-type Star V1355 Orionis

open access: yesThe 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]

open access: yesSymposium - 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
