TL;DR: The luminosity of the progenitor system (especially the companion star) is 10–100 times fainter than previous limits on other type Ia supernova progenitors systems, allowing us to rule out luminous red giants and almost all helium stars as the mass-donating companion to the exploding white dwarf.
Journal ArticleDOI

TL;DR: A temporal series of high-resolution optical spectra of the SN Ia PTF 11kx reveals a complex circumstellar environment that provides an unprecedentedly detailed view of the progenitor system.
Journal ArticleDOI
Evidence for a Spectroscopic Sequence among Type Ia Supernovae
TL;DR: In this paper, a spectral sequence among Type Ia supernovae (SN Ia's) is presented based on the systematic variation of several features seen in the near-maximum light spectrum.
Journal ArticleDOI

TL;DR: In this paper, photometric and spectroscopic observations of SN 2007if, an overluminous (M_V = −20.4), red (B-V = 0.16 at B-band maximum), slow-rising (t_(rise) = 24 days) type Ia supernova (SN Ia) in a very faint (m_g = −14.10) host galaxy.
Journal ArticleDOI
K-corrections and spectral templates of Type Ia supernovae
Eric Hsiao,A. Conley,D. A. Howell,Mark Sullivan,Christopher J. Pritchet,Raymond G. Carlberg,Peter Nugent,Mark M. Phillips +7 more
TL;DR: In this article, the diversity in spectral features of Type Ia supernova (SN Ia) surveys is considered and the authors present a template spectroscopic sequence near maximum light for further improvement on the K-correction estimate.
