The Gaia–Kepler Stellar Properties Catalog. II. Planet Radius Demographics as a Function of Stellar Mass and Age [PDF]
Astronomical Journal, 2020 Studies of exoplanet demographics require large samples and precise constraints on exoplanet host stars. Using the homogeneous Kepler stellar properties derived using the Gaia Data Release 2 by Berger et al., we recompute Kepler planet radii and incident

A GRID OF MHD MODELS FOR STELLAR MASS LOSS AND SPIN-DOWN RATES OF SOLAR ANALOGS [PDF]
, 2013 Stellar winds are believed to be the dominant factor in the spin-down of stars over time. However, stellar winds of solar analogs are poorly constrained due to observational challenges.

The Astrophysical Journal, 2023 The magnetic activity of a star—which modulates the stellar wind outflow—shapes the immediate environments of orbiting (exo)planets and induces atmospheric loss, thereby impacting their habitability.

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.

Theory and Diagnostics of Hot Star Mass Loss [PDF]
Annual Review of Astronomy and Astrophysics, 2021 Massive stars have strong stellar winds that direct their evolution through the upper Hertzsprung–Russell diagram and determine the black hole mass function.

Stellar coronal mass ejections – I. Estimating occurrence frequencies and mass-loss rates [PDF]
, 2017 Stellar coronal mass ejections (CMEs) may play an important role in mass- and angular momentum loss of young Sun-like stars. If occurring frequently, they may also have a strong effect on planetary evolution by increasing atmospheric erosion.

The Fluctuation Theory of the Stellar Mass Loss [PDF]
International Astronomical Union Colloquium, 1981 That we cannot give a justification – or sufficient reasons – for our guesses does not mean that we may not have guessed the truth.K.R. PopperIf studied in detail, the mass flows from the stars appear to be variable. “Mere inspection of solar wind data reveals large variations on a time scale of several days” (Hundhausen, 1972).

Shock-powered light curves of luminous red novae as signatures of pre-dynamical mass loss in stellar mergers [PDF]
, 2017 Luminous red novae (LRN) are a class of optical transients believed to originate from the mergers of binary stars, or "common envelope" events. Their light curves often show secondary maxima, which cannot be explained in the previous models of thermal ...
