Exploring the efficacy and limitations of shock-cooling models: new analysis of Type II supernovae observed by the Kepler mission
Adam Rubin, Avishay Gal-Yam
Modern transient surveys have begun discovering and following supernovae (SNe) shortly after first light---providing systematic measurements of the rise of Type II SNe. We explore…
On the early-time excess emission in hydrogen-poor superluminous supernovae
Paul M. Vreeswijk, Giorgos Leloudas, Avishay Gal-Yam +27
We present the light curves of the hydrogen-poor superluminous supernovae (SLSNe-I) PTF12dam and iPTF13dcc, discovered by the (intermediate) Palomar Transient Factory. Both show ex…
PTF 13efv - An outburst 500 days prior to the SNHunt 275 explosion and its radiative efficiency
E. O. Ofek, S. B. Cenko, N. J. Shaviv +15
The progenitors of some supernovae (SNe) exhibit outbursts with super-Eddington luminosities prior to their final explosions. This behavior is common among Type IIn SNe, but the dr…
The bolometric light curves and physical parameters of stripped-envelope supernovae
S. J. Prentice, P. A. Mazzali, E. Pian +14
The optical and optical/near-infrared pseudo-bolometric light curves of 85 stripped-envelope supernovae (SNe) are constructed using a consistent method and a standard cosmology. Th…
Metallicity from Type II Supernovae from the (i)PTF
F. Taddia, P. Moquist, J. Sollerman +13
Type IIP supernovae (SNe IIP) have recently been proposed as metallicity () probes. The spectral models of Dessart et al. (2014) showed that the pseudo-equivalent width of Fe II…
Unsupervised clustering of Type II supernova light curves
Adam Rubin, Avishay Gal-Yam
As new facilities come online, the astronomical community will be provided with extremely large datasets of well-sampled light curves (LCs) of transient objects. This motivates sys…
