A Survey for hot Central Stars of Planetary Nebulae I. Methods and First Results

Graham C. Kanarek, Michael M. Shara, Jacqueline K. Faherty +2

We present the results of initial spectrographic followup with the Very Large Telescope (UT3, Melipal) for Galactic plane CIV emission-line candidates in the near-infr…

The spin rates of O stars in WR + O binaries. I. Motivation, methodology and first results from SALT

Michael M. Shara, Steven M. Crawford, Dany Vanbeveren +3

The black holes (BH) in merging BH-BH binaries are likely progeny of binary O stars. Their properties, including their spins, will be strongly influenced by the evolution of their…

Late-Time Photometry of Type Ia Supernova SN 2012cg Reveals the Radioactive Decay of Co

Or Graur, David Zurek, Michael M. Shara +3

Seitenzahl et al. (2009) have predicted that roughly three years after its explosion, the light we receive from a Type Ia supernova (SN Ia) will come mostly from reprocessing of el…

HST Images Flash Ionization of Old Ejecta by the 2011 Eruption of Recurrent Nova T Pyxidis

Michael M. Shara, David Zurek, Bradley E. Schaefer +8

T Pyxidis is the only recurrent nova surrounded by knots of material ejected in previous outbursts. Following the eruption that began on 2011 April 14.29, we obtained seven epochs…
