Abstract:
Accurate and densely populated BVRcIc lightcurves of supernovae SN
2011fe in M101, SN 2012aw in M95 and SN 2012cg in NGC 4424 are
presented and discussed. The SN 2011fe lightcurves span a total range
of 342 days, from 17 days pre- to 325 days post-maximum. The
observations of both SN 2012aw and SN 2012cg were stopped by solar
conjunction, when the objects were still bright. The lightcurve for SN
2012aw covers 92 days, that of SN 2012cg spans 44 days. Time and
brightness of maxima are measured, and from the lightcurve shapes and
decline rates the absolute magnitudes are obtained, and the derived
distances are compared to that of the parent galaxies. The color
evolution and the bolometric lightcurves are evaluated in comparison
with those of other well observed supernovae, showing no significant
deviations.
Description:
BVRcIc photometry of the three program supernovae was obtained
with several robotic, remotely or manually controlled telescopes
operated by ANS Collaboration. Technical details of this network of
telescopes running since 2005, their operational procedures and sample
results are presented by Munari et al. (2012BaltA..21...13M 2012BaltA..21...13M). Detailed
analysis of the photometric performances and measurements of the
actual transmission profiles for all the photometric filter sets in
use is presented by Munari and Moretti (2012BaltA..21...13M 2012BaltA..21...13M).
Additional BVRcIc measurements of SN 2011fe and SN 2012aw were
obtained at the Astrokolkhoz Observatory in New Mexico with K35, a
35cm remotely operated telescope which houses a set of Astrodon
BVRcIc multi-layer dielectric filters.
