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…
The Disappearance of the Red Supergiant Progenitor of Supernova 2008bk
Seppo Mattila, Stephen Smartt, Justyn Maund +2
Massive stars end their lives in spectacular supernova explosions. Identifying the progenitor star is a test of stellar evolution and explosion models. Here we show that the progen…
Ultra-bright optical transients are linked with type Ic supernovae
A. Pastorello, S. J. Smartt, M. T. Botticella +41
Recent searches by unbiased, wide-field surveys have uncovered a group of extremely luminous optical transients. The initial discoveries of SN 2005ap by the Texas Supernova Search…
GJ 841B - The Second DQ White Dwarf with Polarized CH Molecular Bands
Tommi Vornanen, Svetlana Berdyugina, Andrei Berdyugin +1
We report a discovery of the circularly polarized CH and molecular bands in the spectrum of the DQ white dwarf GJ 841B. This is only the second such obje…
SDSS J0926+3624: The shortest period eclipsing binary star
C. M. Copperwheat, T. R. Marsh, S. P. Littlefair +12
With orbital periods of the order of tens of minutes or less, the AM Canum Venaticorum stars are ultracompact, hydrogen deficient binaries with the shortest periods of any binary s…
The continuous period search method and its application to the young solar analogue HD 116956
J. Lehtinen, L. Jetsu, T. Hackman +2
We formulate an improved time series analysis method for the analysis of photometry of active stars. This new Continuous Period Search (CPS) method is applied to 12 years of V band…
Multiple Major Outbursts from a Restless Luminous Blue Variable in NGC 3432
A. Pastorello, M. T. Botticella, C. Trundle +16
We present new photometric and spectroscopic observations of an unusual luminous blue variable (LBV) in NGC 3432, covering three major outbursts in October 2008, April 2009 and Nov…
Revisiting Delta Y/Delta Z from multiple main sequences in Globular Clusters: insight from nearby stars
Laura Portinari, Luca Casagrande, Chris Flynn
For nearby K dwarfs, the broadening of the observed Main Sequence at low metallicities is much narrower than expected from isochrones with the standard helium-to-metal enrichment r…
Abundances and density structure of the inner circumstellar ring around SN 1987A
Seppo Mattila, Peter Lundqvist, Per Groeningsson +4
We present optical spectroscopic data of the inner circumstellar ring around SN 1987A from the Anglo-Australian Telescope (AAT) and the Very Large Telescope (VLT) between ~1400 and…
