Eta Carinae's 2014.6 Spectroscopic Event: The Extraordinary He II and N II Features
Kris Davidson, Andrea Mehner, Roberta Humphreys +2
Eta Carinae's spectroscopic events (periastron passages) in 2003, 2009, and 2014 differed progressively. He II 4687 and nearby N II multiplet 5 have special significance because th…
Spectroscopy of superluminous supernova host galaxies. A preference of hydrogen-poor events for extreme emission line galaxies
G. Leloudas, S. Schulze, T. Kruehler +16
Superluminous supernovae (SLSNe) are very bright explosions that were only discovered recently and that show a preference for occurring in faint dwarf galaxies. Understanding why s…
Binarity of the LBV HR Car
Th. Rivinius, H. M. J. Boffin, W. J. de Wit +4
VLTI/AMBER and VLTI/PIONIER observations of the LBV HR Car show an interferometric signature that could not possibly be explained by an extended wind, more or less symmetrically di…
The three-dimensional structure of the Eta Carinae Homunculus
W. Steffen, M. Teodoro, T. I. Madura +6
We investigate, using the modeling code SHAPE, the three-dimensional structure of the bipolar Homunculus nebula surrounding Eta Carinae, as mapped by new ESO VLT/X-Shooter observat…
Near-Infrared Evidence for a Sudden Temperature Increase in Eta Carinae
Andrea Mehner, Kazunori Ishibashi, Patricia Whitelock +4
Aims. Eta Car's ultra-violet, optical, and X-ray light curves and its spectrum suggest a physical change in its stellar wind over the last decade. It was proposed that the mass-los…
