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…
Distribution and Structure of Matter in and around Galaxies
Norbert S. Schulz, Glenn Allen, Mark W. Bautz +24
Understanding the origins and distribution of matter in the Universe is one of the most important quests in physics and astronomy. Themes range from astro-particle physics to chemi…
The SMC SNR 1E0102.2-7219 as a Calibration Standard for X-ray Astronomy in the 0.3-2.5 keV Bandpass
Paul P. Plucinsky, Frank Haberl, Daniel Dewey +8
The flight calibration of the spectral response of CCD instruments below 1.5 keV is difficult in general because of the lack of strong lines in the on-board calibration sources typ…
The Orbital Period of the Wolf-Rayet Binary IC 10 X-1; Dynamic Evidence that the Compact Object is a Black Hole
A. H. Prestwich, R. Kilgard, P. A. Crowther +6
IC 10 X-1 is a bright (Lx=10^38 ergs/s) variable X-ray source in the local group starburst galaxy IC 10. The most plausible optical counterpart is a luminous Wolf-Rayet star, makin…
An ultraluminous supersoft source with a 4 hour modulation in NGC 4631
S. Carpano, A. M. T. Pollock, A. R. King +2
Context. Supersoft X-ray sources (SSSs) are characterised by very low temperatures (< 100 eV). Classical SSSs have bolometric luminosities in the range of 10^36-10^38 erg/s and are…
On the optical counterpart of NGC300 X-1 and the global Wolf-Rayet content of NGC300
Paul A Crowther, S. Carpano, L. J. Hadfield +1
(Conext:) Surveys of Wolf-Rayet (WR) populations in nearby galaxies provide tests of evolutionary models plus Type Ib/c supernova progenitors. This spectroscopic study complements…
