SN2007ax : An Extremely Faint Type Ia Supernova
M. M. Kasliwal, E. O. Ofek, A. Gal-Yam +8
We present multi-band photometric and optical spectroscopic observations of SN2007ax, the faintest and reddest Type Ia supernova (SNIa) yet observed. With M_B = -15.9 and (B-V)max…
The type IIb SN 2008ax: spectral and light curve evolution
A. Pastorello, M. M. Kasliwal, R. M. Crockett +12
We present spectroscopy and photometry of the He-rich supernova (SN) 2008ax. The early-time spectra show prominent P-Cygni H lines, which decrease with time and disappear completel…
Massive stars exploding in a He-rich circumstellar medium. I. Type Ibn (SN 2006jc-like) events
A. Pastorello, S. Mattila, L. Zampieri +26
We present new spectroscopic and photometric data of the type Ibn supernovae 2006jc, 2000er and 2002ao. We discuss the general properties of this recently proposed supernova family…
Supernovae in Low-Redshift Galaxy Clusters: Observations by the Wise Observatory Optical Transient Search (WOOTS)
Avishay Gal-Yam, Dan Maoz, Puragra Guhathakurta +1
We describe the Wise Observatory Optical Transient Search (WOOTS), a survey for supernovae (SNe) and other variable and transient objects in the fields of redshift 0.06-0.2 Abell g…
Constraints on Circumstellar Material Around the Type Ia Supernova 2007af
Joshua D. Simon, Avishay Gal-Yam, Bryan E. Penprase +9
Patat et al. recently inferred the existence of circumstellar material around a normal Type Ia supernova (SN) for the first time, finding time-variable Na I D absorption lines in t…
Upper limit for circumstellar gas around the Type Ia SN 2000cx
F. Patat, S. Benetti, S. Justham +8
The nature of the companion stars in Type Ia Supernova (SNe) progenitor systems remains unclear. One possible way to discriminate between different scenarios is the presence (or ab…
