Hydrogen-Poor Circumstellar Shells from Pulsational Pair-Instability Supernovae with Rapidly Rotating Progenitors
E. Chatzopoulos, J. Craig Wheeler
In certain mass ranges, massive stars can undergo a violent pulsation triggered by the electron/positron pair instability that ejects matter, but does not totally disrupt the star.…
Self-shielding of Soft X-rays in SN Ia Progenitors
J. Craig Wheeler, David A. Pooley
There are insufficient super soft (~ 0.1 keV) X-ray sources in either spiral or elliptical galaxies to account for the rate of explosion of Type Ia supernovae in either the single…
Testing SNe Ia distance measurement methods with SN 2011fe
J. Vinko, K. Sarneczky, K. Takats +17
The nearby, bright, almost completely unreddened Type Ia supernova 2011fe in M101 provides a unique opportunity to test both the precision and the accuracy of the extragalactic dis…
The Very Young Type Ia Supernova 2012cg: Discovery and Early-Time Follow-Up Observations
Jeffrey M. Silverman, Mohan Ganeshalingam, S. Bradley Cenko +15
On 2012 May 17.2 UT, only 1.5 +/- 0.2 d after explosion, we discovered SN 2012cg, a Type Ia supernova (SN Ia) in NGC 4424 (d ~ 15 Mpc). As a result of the newly modified strategy e…
Effects of Rotationally-Induced Mixing in Compact Binary Systems with Low-Mass Secondaries and in Single Solar-Type Stars
Emmanouil Chatzopoulos, Edward L. Robinson, J. Craig Wheeler
Many population synthesis and stellar evolution studies have addressed the evolution of close binary systems in which the primary is a compact remnant and the secondary is filling…
VLT Spectropolarimetry of the Type Ia SN2005ke - A step towards understanding subluminous events
F. Patat, P. Hoeflich, D. Baade +3
We performed optical spectropolarimetric observations of the subluminous Type Ia SN2005ke at 3 epochs (days -8, -7, and +76). The explosion properties are derived by comparing the…
