Mapping the core of the Tarantula Nebula with VLT-MUSE II. The spectroscopic Hertzsprung-Russell diagram of OB stars in NGC 2070
N. Castro, P. A. Crowther, C. J. Evans +7
We present the spectroscopic analysis of 333 OB-type stars extracted from VLT-MUSE observations of the central 30 x 30 pc of NGC 2070 in the Tarantula Nebula on the Large Magellani…
Walking along Cosmic History: Metal-poor Massive Stars
M. Garcia, C. J. Evans, A. Wofford +7
Multiple generations of massive stars have lived and died during Cosmic History, invigorating host galaxies with ionizing photons, kinetic energy, fresh material and stellar-size b…
The low-luminosity accretion disc wind of the black hole transient V4641 Sagittarii
Teo Muñoz-Darias, Manuel A. P. Torres, Michael R. Garcia
We present an optical spectroscopic study of the black hole X-ray transient V4641 Sgr (=SAX J1819.3-2525) covering the 1999, 2002 and 2004 outbursts. The spectra were taken over 22…
EG Andromedae: A New Orbit and Additional Evidence for a Photoionized Wind
Scott J. Kenyon, Michael R. Garcia
We analyze a roughly 20 yr set of spectroscopic observations for the symbiotic binary EG And. Radial velocities derived from echelle spectra are best-fit with a circular orbit havi…
Around 200 new X-ray binary IDs from 13 years of Chandra observations of the M31 center
R. Barnard, M. R. Garcia, F. Primini +3
We have created 0.3--10 keV, 13 year, unabsorbed luminosity lightcurves for 528 X-ray sources in the central 20' of M31. We have 174 Chandra observations spaced at ~1 month interva…
The second ULX transient in M31: Chandra, HST and XMM observations, and evidence for an extended corona
R. Barnard, M. Garcia, S. S. Murray
XMM J004243.6+412519 is a transient X-ray source in M31, first discovered 2012 January 15. Different approaches to fitting the brightest follow-up observation gave luminosities 1.3…
