Mass-Losing Semiregular Variable Stars in Baade's Windows [PDF]

, 2001
By cross-correlating the results of two recent large-scale surveys, the general properties of a well defined sample of semi-regular variable stars have been determined.

Atmospheric Mass Loss During Planet Formation: The Importance of Planetesimal Impacts [PDF]

, 2014
We quantify the atmospheric mass loss during planet formation by examining the contributions to atmospheric loss from both giant impacts and planetesimal accretion. Giant impacts cause global motion of the ground.

Mass loss and stellar superwinds [PDF]

Philosophical 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.

Cepheid Mass-loss and the Pulsation -- Evolutionary Mass Discrepancy

, 2008
I investigate the discrepancy between the evolution and pulsation masses for Cepheid variables. A number of recent works have proposed that non-canonical mass-loss can account for the mass discrepancy.

Radio emission from the massive stars in the Galactic Super Star Cluster Westerlund 1 [PDF]

, 2009
Current mass-loss rate estimates imply that main sequence winds are not sufficient to strip away the H-rich envelope to yield Wolf-Rayet (WR) stars. The rich transitional population of Westerlund 1 (Wd 1) provides an ideal laboratory to observe mass-loss

Mass-Loss from Spinning Stars [PDF]

Highlights of Astronomy, 1980
AbstractThe effects of mass-loss and angular momentum loss on the evolution of massive stars are discussed bringing out the main results as well as the limitations of recent studies. It is pointed out that an acceptable theory of stellar winds in early as well as late type stars is needed as well as a satisfactory assessment of a number of ...
