Optical and Near-IR Observations of the Faint and Fast 2008ha-like Supernova 2010ae
M. D. Stritzinger, E. Hsiao, S. Valenti +21
A comprehensive set of optical and near-infrared (NIR) photometry and spectroscopy is presented for the faint and fast 2008ha-like supernova (SN) 2010ae. Contingent on the adopted…
Persistent C II Absorption in the Normal Type Ia Supernova 2002fk
Régis Cartier, Mario Hamuy, Giuliano Pignata +16
We present well-sampled photometry of SN 2002fk starting 12 days before maximum light through 122 days after peak brightness, along with a series of 15 optical spectra f…
SN 2009N: Linking normal and subluminous type II-P SNe
K. Takáts, M. L. Pumo, N. Elias-Rosa +31
We present ultraviolet, optical, near-infrared photometry and spectroscopy of SN 2009N in NGC 4487. This object is a type II-P supernova with spectra resembling those of subluminou…
On the Source of the Dust Extinction in Type Ia Supernovae and the Discovery of Anomalously Strong Na I Absorption
M. M. Phillips, Joshua D. Simon, Nidia Morrell +28
High-dispersion observations of the Na I D 5890, 5896 and K I 7665, 7699 interstellar lines, and the diffuse interstellar band at 5780 Angstroms in the spectra of 32 Type Ia supern…
Properties of Newly Formed Dust Grains in The Luminous Type IIn Supernova 2010jl
K. Maeda, T. Nozawa, D. K. Sahu +15
Supernovae (SNe) have been proposed to be the main production sites of dust grains in the Universe. Our knowledge on their importance to dust production is, however, limited by obs…
Spectroscopy of Type Ia Supernovae by the Carnegie Supernova Project
Gastón Folatelli, Nidia Morrell, Mark M. Phillips +27
This is the first release of optical spectroscopic data of low-redshift Type Ia supernovae (SNe Ia) by the Carnegie Supernova Project including 604 previously unpublished spectra o…
