What's happening around Herbig Ae stars?: investigating circumstellar activity in young intermediate mass stars with optical and near-infrared spectroscopy
(2001)We have investigated the optical and near-infrared spectral behavior of the intermediate mass, pre-main sequence Herbig Ae stars, with particular emphasis on variability and evolution. The evolutionary state of Herbig Ae ... -
X-ray Binary Evolution and the Connection to Star Formation in Nearby Galaxies with the Chandra Local Volume Survey
(2014-02-24)X-ray binaries, especially those with a massive stellar companion, provide a unique probe through which one can study the end-points of high-mass stellar evolution while simultaneously tracing recent star formation. In ... -
X-ray Insights into Massive Star Evolution: the X-ray Source Population of M33 as seen by XMM-Newton, Chandra, and the Hubble Space Telescope
Massive stars are key drivers in the cycle of star formation and overall galactic chemical evolution, but many aspects of the evolution of high-mass stars, in particular the end stages of their lifetimes, are difficult to ...
