Stellar mass-loss near the Eddington limit. Tracing the sub-photospheric layers of classical Wolf-Rayet stars [PDF]
Context. Towards the end of their evolution, hot massive stars develop strong stellar winds and appear as emission line stars, such as Wolf-Rayet (WR) stars or luminous blue variables (LBVs).

CONSTRAINING SATELLITE GALAXY STELLAR MASS LOSS AND PREDICTING INTRAHALO LIGHT. I. FRAMEWORK AND RESULTS AT LOW REDSHIFT [PDF]
We introduce a new technique that uses galaxy clustering to constrain how satellite galaxies lose stellar mass and contribute to the diffuse “intrahalo light” (IHL).

Dynamical effects of stellar mass-loss on a Kuiper-like belt [PDF]
A quarter of DA white dwarfs are metal polluted, yet elements heavier than helium sink down through the stellar atmosphere on time-scales of days. Hence, these white dwarfs must be the currently accreting material containing heavy elements.

A Clumping-independent Diagnostic of Stellar Mass-Loss Rates: Rapid Clump Destruction in Adiabatic Colliding Winds [PDF]
Clumping in hot star winds can significantly affect estimates of mass-loss rates, the inferred evolution of the star, and the environmental impact of the wind.

An exoplanet's response to anisotropic stellar mass loss during birth and death [PDF]
The birth and death of planets may be affected by mass outflows from their parent stars during the T-Tauri or post-main-sequence phases of stellar evolution. These outflows are often modelled to be isotropic, but this assumption is not realistic for fast

Tracers of stellar mass loss - I. Optical and near-IR colours and surface brightness fluctuations [PDF]
We present optical and infrared (IR) integrated colours and surface brightness fluctuation (SBF) magnitudes, computed from stellar population synthesis models that include emission from the dusty envelopes surrounding thermally pulsing asymptotic giant ...

Stellar coronal mass ejections [PDF]
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 ...

The California-Kepler Survey. X. The Radius Gap as a Function of Stellar Mass, Metallicity, and Age [PDF]
In 2017, the California-Kepler Survey (CKS) published its first data release (DR1) of high-resolution optical spectra of 1305 planet hosts. Refined CKS planet radii revealed that small planets are bifurcated into two distinct populations, super-Earths ...
