Evidence for the Strong Effect of Gas Removal on the Internal Dynamics of Young Stellar Clusters [PDF]
, 2006 We present detailed luminosity profiles of the young massive clusters M82-F, NGC 1569-A, and NGC 1705-1 which show significant departures from equilibrium (King and EFF) profiles.

THE IMPACT OF GAS STRIPPING AND STELLAR MASS LOSS ON SATELLITE GALAXY EVOLUTION [PDF]
, 2010 Current semi-analytic models of galaxy formation overpredict the fraction of passive small late-type satellite galaxies in dense environments by a factor of two to three.

Pulsation Period Change & Classical Cepheids: Probing the Details of Stellar Evolution
, 2014 Measurements of secular period change probe real-time stellar evolution of classical Cepheids making these measurements powerful constraints for stellar evolution models, especially when coupled with interferometric measurements. In this work, we present

Reaction of Massive Clusters to Gas Expulsion - The cluster density dependence [PDF]
, 2013 The expulsion of the unconverted gas at the end of the star formation process potentially leads to the expansion of the just formed stellar cluster and membership loss.

The transition mass-loss rate: Calibrating the role of line-driven winds in massive star evolution
, 2012 A debate has arisen regarding the importance of stationary versus eruptive mass loss for massive star evolution. The reason is that stellar winds have been found to be clumped, which results in the reduction of unclumped empirical mass-loss rates.

Stellar mass loss, rotation and the chemical enrichment of early-type galaxies [PDF]
, 2009 We present a comparison between the [Ca,C,N/Fe]-mass relations observed in local spheroids and the results of a chemical evolution model which already successfully reproduces the [Mg/Fe]-mass and the [Fe/H]-mass relations in these systems.

The Impact of Hot Jupiters on the Spin-down of their Host Stars [PDF]
, 2010 We present a numerical Magnetohydrodynamic (MHD) study of the dependence of stellar mass and angular momentum- loss rates on the orbital distance to close-in giant planets.

OB STARS AND STELLAR BOW SHOCKS IN CYGNUS-X: A NOVEL LABORATORY ESTIMATING STELLAR MASS LOSS RATES [PDF]
, 2009 We use mid-infrared images from the Spitzer Space Telescope Cygnus X Legacy Survey to search for stellar bow shocks (BSs), a signature of early-type “runaway” stars with high space velocities.

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 ...
