Journal ArticleDOI
Deflagrations in hybrid CONe white dwarfs: a route to explain the faint Type Iax supernova 2008ha
M. Kromer,Sebastian T. Ohlmann,Sebastian T. Ohlmann,Ruediger Pakmor,Ashley J. Ruiter,Wolfgang Hillebrandt,Kai Marquardt,Kai Marquardt,Friedrich K. Röpke,Friedrich K. Röpke,Ivo R. Seitenzahl,Stuart A. Sim,S. Taubenberger +12 more
TL;DR: In this paper, an off-centre deflagration in a near-M-Ch hybrid white dwarfs was investigated under the assumption that nuclear burning only occurs in carbon-rich material.
Journal ArticleDOI
Three-dimensional simulations of the interaction between Type Ia supernova ejecta and their main sequence companions
Zheng-Wei Liu,Ruediger Pakmor,Friedrich K. Roepke,P. V. F. Edelmann,Bo Wang,M. Kromer,Wolfgang Hillebrandt,Zhong-Tao Han +7 more
TL;DR: In this article, the impact of the SN blast wave on these companion stars is followed in three-dimensional hydrodynamic simulations employing the SPH code GADGET3, and the stripped masses range from 0.11 to 0.18 M_sun.
Journal ArticleDOI
No trace of a single-degenerate companion in late spectra of SNe 2011fe and 2014J
Peter Lundqvist,A. Nyholm,F. Taddia,Jesper Sollerman,Joel Johansson,Cecilia Kozma,Natalia Lundqvist,Claes Fransson,P. M. Garnavich,M. Kromer,Benjamin J. Shappee,Ariel Goobar +11 more
TL;DR: In this paper, the spectral lines sought for are H-alpha, [O I] 6300 and [Ca II] 7291,7324, and the expected width of these lines is about 1000 km/s.

No trace of a single-degenerate companion in late spectra of supernovae 2011fe and 2014J
Peter Lundqvist,Anders Nyholm,Francesco Taddia,Jesper Sollerman,Joel Johansson,Cecilia Kozma,Natalia Lundqvist,Claes Fransson,Peter M. Garnavich,M. Kromer,Benjamin J. Shappee,Ariel Goobar +11 more
TL;DR: In this paper, the spectral lines sought for are H, [O I] 6300, and [Ca II] 7291,7324, and the expected width of these lines is 1000 km s 1, which in the case of the [Ca I] lines blend to a broader feature.
Journal ArticleDOI
The Earliest Near-infrared Time-series Spectroscopy of a Type Ia Supernova

TL;DR: In this article, the authors presented ten medium-resolution, high signal-to-noise ratio near-infrared (NIR) spectra of SN 2011fe from SpeX on the NASA Infrared Telescope Facility (IRTF) and Gemini Near-Infrared Spectrograph (GNIRS) on Gemini North, obtained as part of the Carnegie Supernova Project.
