A spectral and spatial analysis of eta Carinae's diffuse X-ray emission using CHANDRA
Kerstin Weis, Michael F. Corcoran, Dominik J. Bomans +1
The luminous unstable star (star system) eta Carinae is surrounded by an optically bright bipolar nebula, the Homunculus and a fainter but much larger nebula, the so-called outer e…
Chandra Observations of a Young Embedded Magnetic B Star in the rho Ophiuchus Cloud
Kenji Hamaguchi, Michael F. Corcoran, Kensuke Imanishi
This paper reports on an analysis of two Chandra X-ray observations of the young magnetic B star rho Ophiuchus S1. X-ray emission from the star was detected in both observations. T…
Cosmic Ray Acceleration by Stellar Associations? The Case of Cygnus OB2
Yousaf Butt, Paula Benaglia, Jorge Combi +10
The origins of all extra-solar cosmic rays -- both the ultra high-energy and lower energy Galactic variety -- remain unclear. It has been argued that the large scale shocks and tur…
Chandra Grating Spectroscopy of the X-ray Binary 4U 1700-37 in a Flaring State
B. Boroson, S. Vrtilek, T. Kallman +1
Chandra X-ray Observatory grating spectra of the supergiant X-ray Binary 4U 1700-37 reveal emission lines from hydrogen and helium-like S, Si, Mg, and Ne in the 4-13 A range. The s…
CHANDRA/VLA Follow-up of TeV J2032+4131, the Only Unidentified TeV Gamma-ray Source
Yousaf Butt, Paula Benaglia, Jorge Combi +10
The HEGRA Cherenkov telescope array group recently reported a steady and extended unidentified TeV gamma-ray source lying at the outskirts of Cygnus OB2. This is the most massive s…
