The Explosion of Helium Stars Evolved with Mass Loss [PDF]
The Astrophysical Journal, 2020 Abstract Light curves, explosion energies, and remnant masses are calculated for a grid of supernovae resulting from massive helium stars that have been evolved including mass loss. These presupernova stars should approximate the results of binary evolution for stars in interacting systems that lose their envelopes close to the time of ...

A new mass-loss rate prescription for red supergiants [PDF]
Monthly Notices of the Royal Astronomical Society, 2020 Evolutionary models have shown the substantial effect that strong mass-loss rates ($\dot{M}$s) can have on the fate of massive stars. Red supergiant (RSG) mass-loss is poorly understood theoretically, and so stellar models rely on purely empirical ...

THE SEARCH FOR SIGNATURES OF TRANSIENT MASS LOSS IN ACTIVE STARS [PDF]
The Astrophysical Journal, 2016 ABSTRACT The habitability of an exoplanet depends on many factors. One such factor is the impact of stellar eruptive events on nearby exoplanets. Currently this is poorly constrained due to heavy reliance on solar scaling relationships and a lack of experimental evidence.

Integrated mass loss of evolved stars in M4 using asteroseismology [PDF]
Monthly notices of the Royal Astronomical Society, 2022 Mass loss remains a major uncertainty in stellar modelling. In low-mass stars, mass loss is most significant on the red giant branch (RGB), and will impact the star’s evolutionary path and final stellar remnant.

New predictions for radiation-driven, steady-state mass-loss and wind-momentum from hot, massive stars [PDF]
Astronomy & Astrophysics, 2020 Context. Reliable predictions of mass-loss rates are important for massive-star evolution computations. Aims. We aim to provide predictions for mass-loss rates and wind-momentum rates of O-type stars, while carefully studying the behaviour of these winds

Adiabatic Mass Loss in Binary Stars. III. From the Base of the Red Giant Branch to the Tip of the Asymptotic Giant Branch [PDF]
Astrophysical Journal, 2020 The distinguishing feature of the evolution of close binary stars is the role played by the mass exchange between the component stars. Whether or not the mass transfer is dynamically stable is one of the essential questions in binary evolution.

Evolution and Mass Loss of Cool Aging Stars: A Daedalean Story [PDF]
Annual Review of Astronomy and Astrophysics, 2020 A multitude of phenomena—such as the chemical enrichment of the Universe, the mass spectrum of planetary nebulae, white dwarfs and gravitational wave progenitors, the frequency distribution of supernovae, the fate of exoplanets, etc.—are highly regulated

The VLT-FLAMES survey of massive stars: mass loss and rotation of early-type stars in the SMC [PDF]
, 2006 We have studied the optical spectra of a sample of 31 O- and early B-type stars in the Small Magellanic Cloud, 21 of which are associated with the young massive cluster NGC 346.

Circumstellar molecular line emission from S-type AGB stars: Mass-loss rates and SiO abundances [PDF]
, 2009 Aims: The main aim is to derive reliable mass-loss rates and circumstellar SiO abundances for a sample of 40 S-type AGB stars based on new multi-transitional CO and SiO radio line observations.
