Effects Of Rotationally Induced Mixing In Compact Binary Systems With Low-Mass Secondaries And In Single Solar-Type Stars

Chatzopoulos, Emmanouil; Robinson, Edward L.; Wheeler, J. Craig (2012-08)

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 its Roche lobe, thus triggering mass ...

Effects Of Rotation On The Minimum Mass Of Primordial Progenitors Of Pair-Instability Supernovae

Chatzopoulos, Emmanouil; Wheeler, J. Craig (2012-03)

The issue of which stars may reach the conditions of electron/positron pair-formation instability is of importance to understand the final evolution both of the first stars and of contemporary stars. The criterion to enter ...

We present follow-up observations of an optical transient (OT) discovered by ROTSE on 2009 January 21. Photometric monitoring was carried out with ROTSE-IIIb in the optical and Swift in the UV up to +70 days after discovery. ...

Aspherical Core-Collapse Supernovae In Red Supergiants Powered By Nonrelativistic Jets

Couch, Sean M.; Wheeler, J. Craig; Milosavljevic, Milos (2009-05)

We explore the observational characteristics of jet-driven supernovae (SNe) by simulating bipolar-jet-driven explosions in a red supergiant (RSG) progenitor. We present results of four models in which we hold the injected ...
