Spectroscopy, MOST Photometry, and Interferometry of MWC 314: Is it an LBV or an interacting binary?
Noel D. Richardson, Anthony F. J. Moffat, Raphaël Maltais-Tariant +34
MWC 314 is a bright candidate luminous blue variable that resides in a fairly close binary system, with an orbital period of 60.7530.003 d. We observed MWC 314 with a combinat…
The X-ray Lightcurve of the Supermassive star eta Carinae, 1996--2014
M. F. Corcoran, K. Hamaguchi, J. K. Liburd +9
Eta Carinae is the nearest example of a supermassive, superluminous, unstable star. Mass loss from the system is critical in shaping its circumstellar medium and in determining its…
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…
HST/STIS Ultraviolet Spectroscopy of the Components of the Massive Triple Star delta Ori A
Noel D. Richardson, Anthony F. J. Moffat, Theodore R. Gull +4
The multiple star system of delta Orionis is one of the closest examples of a system containing a luminous O-type, bright giant star (component Aa1). It is often used as a spectral…
A Coordinated X-ray and Optical Campaign of the Nearest Massive Eclipsing Binary, delta Orionis Aa: III. Analysis of Optical Photometric MOST and Spectroscopic (Ground Based) Variations
Herbert Pablo, Noel D. Richardson, Anthony F. J. Moffat +44
We report on both high-precision photometry from the MOST space telescope and ground-based spectroscopy of the triple system delta Ori A consisting of a binary O9.5II+early-B (Aa1…
A coordinated X-ray and Optical Campaign of the Nearest Massive Eclipsing Binary, Orionis Aa: IV. A multiwavelength, non-LTE spectroscopic analysis
T. Shenar, L. Oskinova, W. -R. Hamann +13
Eclipsing systems of massive stars allow one to explore the properties of their components in great detail. We perform a multi-wavelength, non-LTE analysis of the three components…
