A Massive Progenitor of the Luminous Type IIn Supernova 2010jl
Nathan Smith, Weidong Li, Adam A. Miller +6
The bright, nearby, recently discovered supernova SN2010jl is a member of the rare class of relatively luminous Type~IIn events. Here we report archival HST observations of its hos…
PTF10nvg: An Outbursting Class I Protostar in the Pelican/North American Nebula
Kevin R. Covey, Lynne A. Hillenbrand, Adam A. Miller +28
During a synoptic survey of the North American Nebula region, the Palomar Transient Factory (PTF) detected an optical outburst (dubbed PTF10nvg) associated with the previously unst…
Evidence for an FU Orionis-like Outburst from a Classical T Tauri Star
Adam A. Miller, Lynne A. Hillenbrand, Kevin R. Covey +26
We present pre- and post-outburst observations of the new FU Orionis-like young stellar object PTF 10qpf (also known as LkHa 188-G4 and HBC 722). Prior to this outburst, LkHa 188-G…
PTF10fqs: A Luminous Red Nova in the Spiral Galaxy Messier 99
Mansi M. Kasliwal, S. R. Kulkarni, Iair Arcavi +38
The Palomar Transient Factory (PTF) is systematically charting the optical transient and variable sky. A primary science driver of PTF is building a complete inventory of transient…
Fourteen Months of Observations of the Possible Super-Chandrasekhar Mass Type Ia Supernova 2009dc
Jeffrey M. Silverman, Mohan Ganeshalingam, Weidong Li +3
In this paper, we present and analyse optical photometry and spectra of the extremely luminous and slowly evolving Type Ia supernova (SN Ia) 2009dc, and offer evidence that it is a…
