The UV/optical spectra of the Type Ia supernova SN 2010jn: a bright supernova with outer layers rich in iron-group elements
S. Hachinger, P. A. Mazzali, M. Sullivan +19
Radiative transfer studies of Type Ia supernovae (SNe Ia) hold the promise of constraining both the time-dependent density profile of the SN ejecta and its stratification by elemen…
PTF11kx: A Type-Ia Supernova with a Symbiotic Nova Progenitor
B. Dilday, D. A. Howell, S. B. Cenko +32
There is a consensus that Type-Ia supernovae (SNe Ia) arise from the thermonuclear explosion of white dwarf stars that accrete matter from a binary companion. However, direct obser…
X-ray emission from supernovae in dense circumstellar matter environments: A search for collisionless shocks
E. O. Ofek, D. Fox, S. B. Cenko +21
(Abridged). The optical light curve of some SNe may be powered by the outward diffusion of the energy deposited by the explosion shock in optically thick circumstellar matter (CSM)…
Analysis of the Early-Time Optical Spectra of SN 2011fe in M101
J. T. Parrent, D. A. Howell, B. Friesen +35
The nearby Type Ia supernova SN 2011fe in M101 (cz=241 km s^-1) provides a unique opportunity to study the early evolution of a "normal" Type Ia supernova, its compositional struct…
Classical Novae in Andromeda: Light Curves from the Palomar Transient Factory and GALEX
Yi Cao, Mansi M. Kasliwal, James D. Neill +10
We present optical light curves of twenty-nine novae in M31 during the 2009 and 2010 observing seasons of the Palomar Transient Factory (PTF). The dynamic and rapid cadences in PTF…
Asteroid rotation periods from the Palomar Transient Factory survey
D. Polishook, E. O. Ofek, A. Waszczak +17
The Palomar Transient Factory (PTF) is a synoptic survey designed to explore the transient and variable sky in a wide variety of cadences. We use PTF observations of fields that we…
