The origin and impact of Wolf-Rayet-type mass loss
Andreas A. C. Sander, Jorick S. Vink, Erin R. Higgins +3
Classical Wolf-Rayet (WR) stars mark an important stage in the late evolution of massive stars. As hydrogen-poor massive stars, these objects have lost their outer layers, while st…
Discovery of O stars in the tidal Magellanic Bridge: Stellar parameters, abundances, and feedback of the nearest metal-poor massive stars and their implication for the Magellanic System ecology
Varsha Ramachandran, L. M. Oskinova, W. -R. Hamann
The Magellanic Bridge stretching between the SMC and LMC is the nearest tidally stripped intergalactic environment and has a low average metallicity of . Here we re…
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…
The cooling-down central star of the planetary nebula SwSt\,1: a late thermal pulse in a massive post-AGB star?
Marcin Hajduk, Helge Todt, Wolf-Rainer Hamann +3
SwSt 1 (PN G001.5-06.7) is a bright and compact planetary nebula containing a late [WC]-type central star. Previous studies suggested that the nebular and stellar lines are slowly…
Phase-dependent study of near-infrared disk emission lines in LB-1
Jifeng Liu, Zheng Zheng, Roberto Soria +19
The mass, origin and evolutionary stage of the binary system LB-1 has been the subject of intense debate, following the claim that it hosts an 70 black hole, in st…
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…
