Abstract:
We study PTF11mnb, a He-poor supernova (SN) whose light curves
resemble those of SN 2005bf, a peculiar double-peaked
stripped-envelope (SE) SN, until the declining phase after the main
peak. We investigate the mechanism powering its light curve and the
nature of its progenitor star.
Optical photometry and spectroscopy of PTF11mnb are presented. We
compared light curves, colors and spectral properties to those of SN
2005bf and normal SE SNe. We built a bolometric light curve and
modeled this light curve with the SuperNova Explosion Code (SNEC)
hydrodynamical code explosion of a MESA progenitor star and
semi-analytic models.
Description:
The Palomar Transient Factory first detected PTF11mnb at
RA=00:34:13.25 and DE=+02:48:31.4 (J2000.0) on JD 2455804.857
(Aug. 31 2011) (g = 21:07±0.31mag ) using the 48-inch Samuel Oschin
telescope (P48) at Palomar Observatory, equipped with the 96 Mpixel
mosaic camera CFH12K.
PTF11mnb was observed with P48 in the g band until ∼60d and until
∼50-days in the r band.
We also made use of the Palomar 60-inch telescope (P60), with which we
observed the SN in Bgri bands, starting at ∼20d with the r band
(Bgi band coverage started from ∼40d).
The SN was detected for the last time at ∼140-days with P60.
