Competitive X-ray and Optical Cooling in the Collisionless Shocks of WR 140

A. M. T. Pollock, M. F. Corcoran, I. R. Stevens +9

WR 140 is a long-period, highly eccentric Wolf-Rayet star binary system with exceptionally well-determined orbital and stellar parameters. Bright, variable X-ray emission is genera…

A Coordinated X-ray and Optical Campaign of the Nearby Massive Binary Orionis Aa: II. X-ray Variability

J. S. Nichols, D. P. Huenemoerder, M. F. Corcoran +18

We present time-resolved and phase-resolved variability studies of an extensive X-ray high-resolution spectral dataset of the Orionis Aa binary system. The four observations, o…

The massive double-lined O-type binary HD 165052

J. I. Arias, N. I. Morrell, R. H. Barba +4

We present a new optical spectroscopic study of the O-type binary HD 165052 based on high- and intermediate-resolution CCD observations. We re-investigated the spectral classificat…

Optical spectroscopy of X-MEGA targets I. CPD -59 2635: A New Double-Lined O type Binary in the Carina Nebula

J. F. Albacete Colombo, N. I. Morrell, V. S. Niemela +1

Optical spectroscopy of CPD -59 2635, one of the O-type stars in the open cluster Trumpler 16 in the Carina Nebula, reveals this star to be a double-lined binary system. We have ob…

Optical spectroscopy of X-Mega targets in the Carina Nebula. II. The massive double-lined O-type binary HD 93205

N. I. Morrell, R. H. Barba, V. S. Niemela +8

A new high-quality set of orbital parameters for the O-type spectroscopic binary HD93205 has been obtained combining echelle and coude CCD observations. The radial velocity orbits…
