SN 2009bb: a Peculiar Broad-Lined Type Ic Supernova
Giuliano Pignata, Maximilian Stritzinger, Alicia Soderberg +23
Ultraviolet, optical, and near-infrared photometry and optical spectroscopy of the broad-lined Type Ic supernova (SN) 2009bb are presented, following the flux evolution from -10 to…
SN 2009md: Another faint supernova from a low mass progenitor
M. Fraser, M. Ergon, J. J. Eldridge +21
We present adaptive optics imaging of the core collapse supernova (SN) 2009md, which we use together with archival \emph{Hubble Space Telescope} data to identify a coincident proge…
Supernova 2008bk and Its Red Supergiant Progenitor
Schuyler D. Van Dyk, Tim J. Davidge, Nancy Elias-Rosa +8
We have obtained limited photometric and spectroscopic data for Supernova (SN) 2008bk in NGC 7793, primarily at >~ 150 d after explosion. We find that it is a Type II-Plateau (II-P…
Accretion Disks in Evolved Cataclysmic Variables
Sergey Zharikov, Gaghik Tovmassian, Andres Aviles +2
We explore conditions and structure of accretion disks in short-period Cata- clysmic Variables (CVs), which have evolved beyond the period minimum. We show that accretion discs in…
Early Results from the Galactic O-Star Spectroscopic Survey: C III Emission Lines in Of Spectra
Nolan R. Walborn, Alfredo Sota, Jesus Maiz Apellaniz +5
On the basis of an extensive new spectroscopic survey of Galactic O stars, we introduce the Ofc category, which consists of normal spectra with C III λ\lambda4647-4650-4652 emissio…
The Onfp Class in the Magellanic Clouds
Nolan R. Walborn, Ian D. Howarth, Christopher J. Evans +8
The Onfp class of rotationally broadened, hot spectra was defined some time ago in the Galaxy, where its membership to date numbers only eight. The principal defining characteristi…
