Structure and Evolution of Pre-Main Sequence Stars
Norbert S. Schulz, Glenn Allen, Mark W. Bautz +28
Low-mass pre-main sequence (PMS) stars are strong and variable X-ray emitters, as has been well established by EINSTEIN and ROSAT observatories. It was originally believed that thi…
Understanding Mass-Loss and the late Evolution of Intermediate Mass Stars: Jets, Disks, Binarity, Dust and Magnetic Fields
Raghvendra Sahai, Bruce Balick, Eric Blackman +7
Almost all stars in the 1-8 Msun range evolve through the Asymptotic Giant Branch (AGB), preplanetary nebula (PPN) and planetary nebula (PN) evolutionary phases. Most stars that le…
The X-Ray Spectrum of a Planetary Nebula at High Resolution: Chandra Gratings Spectroscopy of BD+30 3639
Young Sam Yu, Raanan Nordon, Joel H. Kastner +3
We present the results of the first X-ray gratings spectroscopy observations of a planetary nebula (PN), the X-ray-bright, young BD+30 3639. We observed BD+30 3639 for a total of 3…
The LMC's Top 250: Classification of the Most Luminous Compact 8 micron Sources in the Large Magellanic Cloud
Joel H. Kastner, Stephen L. Thorndike, Paul A. Romanczyk +4
To ascertain the nature of the brightest compact mid-infrared sources in the Large Magellanic Cloud (LMC), we have applied an updated version of the Buchanan et al. (2006) 2MASS-MS…
XMM-NEWTON Detection of X-ray Emission from the Compact Steep Spectrum Radio Galaxy 3C303.1
C. O'Dea, B. Mu, D. Worrall +3
Using XMM we detect faint unresolved X-ray emission from the Compact Steep Spectrum radio galaxy 3C303.1. We detect a thermal component at kT = 0.8 keV which seems likely to be pro…
