SN 2011fu: A type IIb Supernova with a luminous double-peaked light curve
A. Morales-Garoffolo, N. Elias-Rosa, M. Bersten +17
We present optical and near infrared observations of the type IIb supernova (SN) 2011fu from a few days to d after explosion. The SN presents a double-peaked light curve…
The Progenitor of the Type IIb SN 2008ax Revisited
Gastón Folatelli, Melina C. Bersten, Hanindyo Kuncarayakti +3
Hubble Space Telescope observations of the site of the supernova (SN) 2008ax obtained in 2011 and 2013 reveal that the possible progenitor object detected in pre-explosion images w…
The Rise-Time of Type II Supernovae
Santiago Gonzalez-Gaitan, N. Tominaga, J. Molina +14
We investigate the early-time light-curves of a large sample of 223 type II supernovae (SNe) from the Sloan Digital Sky Survey and the Supernova Legacy Survey. Having a cadence of…
Nebular phase observations of the type-Ib supernova iPTF13bvn favour a binary progenitor
H. Kuncarayakti, K. Maeda, M. C. Bersten +9
Aims. We present and analyse late-time observations of the type-Ib supernova with possible pre-supernova progenitor detection, iPTF13bvn, taken at 300 days after the explosio…
Massive stars exploding in a He-rich circumstellar medium. V. Observations of the slow-evolving SN Ibn OGLE-2012-SN-006
A. Pastorello, L. Wyrzykowski, S. Valenti +36
We present optical observations of the peculiar Type Ibn supernova (SN Ibn) OGLE-2012-SN-006, discovered and monitored by the OGLE-IV survey, and spectroscopically followed by PESS…
