    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 ...

    Interaction Between the Broad-Lined Type Ic Supernova 2012ap and Carriers of Diffuse Interstellar Bands 

    Milisavljevic, Dan; Margutti, Raffaella; Crabtree, Kyle N.; Foster, Jonathan B.; Soderberg, Alicia M.; Fesen, Robert A.; Parrent, Jerod T.; Sanders, Nathan E.; Drout, Maria R.; Kamble, Atish; Chakraborti, Sayan; Pickering, Timothy E.; Cenko, S. Bradley; Silverman, Jeffrey M.; Filippenko, Alexei V.; Kirshner, Robert P.; Mazzali, Paolo; Maeda, Keiichi; Marion, G. H. Howie; Vinko, Jozsef; Wheeler, J. Craig (2014-02)
    Diffuse interstellar bands (DIBs) are absorption features observed in optical and near-infrared spectra that are thought to be associated with carbon-rich polyatomic molecules in interstellar gas. However, because the ...

    Modeling The Light Curve Of The Transient Scp06F6 

    Chatzopoulos, Emmanouil; Wheeler, J. Craig; Vinko, Jozsef (2009-10)
    We consider simple models based on core collapse or pair-formation supernovae (SNe) to account for the light curve of the transient SCP06F6. A radioactive decay diffusion model provides estimates of the mass of the required ...

    The Shape Of Cas A 

    Wheeler, J. Craig; Maund, Justyn R.; Couch, Sean M. (2008-04)
    On the basis of optical, IR, and X-ray studies of CasA, we propose a geometry for the remnant based on a " jet-induced'' scenario with significant systematic departures from axial symmetry. In this model, the main jet axis ...

    SN 2008In-Bridging The Gap Between Normal And Faint Supernovae Of Type IIp 

    Roy, Rupak; Kumar, Brijesh; Benetti, Stefano; Pastorello, Andrea; Yuan, Fang; Brown, Peter J.; Immler, Stefan; Fatkhullin, Timur A.; Moskvitin, Alexander S.; Maund, Justyn; Akerlof, Carl W.; Wheeler, J. Craig; Sokolov, Vladimir V.; Quimby, Rorbert M.; Bufano, Filomena; Kumar, Brajesh; Misra, Kuntal; Pandey, S. B.; Elias-Rosa, Nancy; Roming, Peter W. A.; Sagar, Ram (2011-08)
    We present optical photometric and low-resolution spectroscopic observations of the Type II plateau supernova (SN) 2008in, which occurred in the outskirts of the nearly face-on spiral galaxy M61. Photometric data in the ...

    The Unusually Luminous Extragalactic Nova SN 2010U 

    Czekala, Ian; Berger, E.; Chornock, Ryan; Pastorello, A.; Marion, G. H.; Margutti, R.; Botticella, M. T.; Challis, Peter; Ergon, M.; Smartt, S.; Sollerman, Jesper; Vinko, Jozsef; Wheeler, J. Craig (2013-03)
    We present observations of the unusual optical transient SN 2010U, including spectra taken 1.03 days to 15.3 days after maximum light that identify it as a fast and luminous Fe II type nova. Our multi-band light curve ...

    Hydrogen-Poor Circumstellar Shells From Pulsational Pair-Instability Supernovae With Rapidly Rotating Progenitors 

    Chatzopoulos, Emmanouil; Wheeler, J. Craig (2012-12)
    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. After one or more of these pulsations, ...

    Discovery Of The Ultra-Bright Type II-L Supernova 2008es 

    Gezari, S.; Halpern, J. P.; Grupe, D.; Yuan, F.; Quimby, Robert; McKay, T.; Chamarro, D.; Sisson, M. D.; Akerlof, C.; Wheeler, J. Craig; Brown, Peter J.; Cenko, S. Bradley; Rau, A.; Djordjevic, J. O.; Terndrup, D. M. (2009-01)
    We report the discovery by the Robotic Optical Transient Search Experiment (ROTSE-IIIb) telescope of SN 2008es, an overluminous supernova (SN) at z = 0.205 with a peak visual magnitude of -22.2. We present multiwavelength ...
