Abstract:
We present our observations of SN 2010mb, a Type Ic supernova (SN)
lacking spectroscopic signatures of H and He. SN 2010mb has a slowly
declining light curve (LC) (∼600 days) that cannot be powered by
56Ni/56Co radioactivity, the common energy source for Type Ic SNe.
We detect signatures of interaction with hydrogen-free circumstellar
material including a blue quasi-continuum and, uniquely, narrow oxygen
emission lines that require high densities (∼109/cm3). From the
observed spectra and LC, we estimate that the amount of material
involved in the interaction was ∼3 M☉. Our observations are in
agreement with models of pulsational pair-instability SNe described in
the literature.
Description:
Photometry of SN 2010mb was obtained by the P48 (Law et al.
2009PASP..121.1395L 2009PASP..121.1395L; Rau et al. 2009PASP..121.1334R 2009PASP..121.1334R), the gamma-ray
burst camera (Cenko et al. 2006PASP..118.1396C 2006PASP..118.1396C) mounted on the Palomar
60" telescope (P60), the Large Format Camera mounted on the Palomar
200" Hale telescope (P200), and the Low Resolution Imaging
Spectrograph (LRIS) mounted on the 10 m Keck-I telescope (Oke et al.
1995PASP..107..375O 1995PASP..107..375O). Data were reduced using the MKDIFFLC photometry
routine (Gal-Yam et al. 2004ApJ...609L..59G 2004ApJ...609L..59G; 2008ApJ...680..550G 2008ApJ...680..550G),
except for P48 data reduced using point-spread function (PSF) photometry
on image subtractions. The PTF data processing is discussed in Laher
(2014PASP..126..674L 2014PASP..126..674L), while the photometric calibration is discussed
in Ofek et al. (2012PASP..124...62O 2012PASP..124...62O; 2012PASP..124..854O 2012PASP..124..854O, Cat. II/313).
