Correlated X-ray and optical variability in the O-type supergiant zeta Puppis
Joy S. Nichols, Yael Naze, David P. Huenemoerder +11
Analysis of the recent long exposure Chandra X-ray observation of the early-type O star zeta Pup shows clear variability with a period previously reported in optical photometric st…
An extensive spectroscopic time series of three Wolf-Rayet stars -- II. A search for wind asymmetries in the dust-forming WC7 binary WR137
N. St-Louis, C. Piaulet, N. D. Richardson +39
We present the results of a four-month, spectroscopic campaign of the Wolf-Rayet dust-making binary, WR137. We detect only small-amplitude, random variability in the CIII5696 emiss…
A Deep Exposure in High Resolution X-Rays Reveals the Hottest Plasma in the Puppis Wind
David P. Huenemoerder, Richard Ignace, Nathan A. Miller +9
We have obtained a very deep exposure (813 ks) of Puppis (O4 supergiant) with the Chandra/HETG Spectrometer. Here we report on analysis of the 1-9 Å region, especially well su…
CO, Water, and Possible Methanol in Eta Carinae Approaching Periastron
Patrick W. Morris, Steven B. Charnley, Michael Corcoran +12
In circumstellar gas, the complex organic molecule methanol has been found almost exclusively around young stellar objects, and is thus regarded as a signpost of recent star format…
International observational campaign of the 2014 eclipse of EE Cep
D. Pieńkowski, C. Gałan, T. Tomov +64
Context. EE Cep is one of few eclipsing binary systems with a dark, dusty disk around an invisible object similar to ε Aur. The system is characterized by grey and asymmetric eclip…
