Mass loss and stellar superwinds [PDF]

open access: yesPhilosophical Transactions of the Royal Society 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.

Continuous stellar mass-loss in N-body models of galaxies [PDF]

open access: yes, 2001
We present an N-body computer code - aimed at studies of galactic dynamics - with a CPU-efficient algorithm for a continuous (i.e. time-dependent) stellar mass-loss. First, we summarize available data on stellar mass-loss and derive the long-term (20 Gyr)

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

Boil-off of red supergiants: mass loss and type II-P supernovae [PDF]

open access: yesThe Open Journal of Astrophysics
The mass loss mechanism of red supergiant stars is not well understood, even though it has crucial consequences for their stellar evolution and the appearance of supernovae that occur upon core-collapse.

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.

Supernova Precursor Emission and the Origin of Pre-explosion Stellar Mass Loss [PDF]

open access: goldAstrophysical Journal, 2022
A growing number of core-collapse supernovae (SNe) that show evidence for interaction with dense circumstellar medium (CSM) are accompanied by “precursor” optical emission rising weeks to months prior to the explosion.

Stellar Mass Loss and Pulsation [PDF]

open access: yesInternational Astronomical Union Colloquium, 1989
AbstractMass loss at rates sufficient to alter the evolution of stars is known to occur during the pre-main sequence evolution of most stars, on the main sequence for massive stars, and during advanced evolutionary phases when the luminosity is high and the effective temperature is low.

Supernovae and Stellar Mass Loss [PDF]

open access: yesHighlights of Astronomy, 1986
AbstractType I supernovae can be modeled as the carbon deflagration of white dwarfs and Type II supernovae as the explosions of massive stars with hydrogen envelopes. The massive stars at the ends of their lives are expected to be red supergiants, which are observed to have slow, dense winds.

Signatures of the core-powered mass-loss mechanism in the exoplanet population: dependence on stellar properties and observational predictions [PDF]

open access: greenMonthly notices of the Royal Astronomical Society, 2020
Recent studies have shown that atmospheric mass-loss powered by the cooling luminosity of a planet’s core can explain the observed radius valley separating super-Earths and sub-Neptunes, even without photoevaporation.
