Abstract:
The luminous Type IIn SN 2010jl shows strong signs of interaction
between the SN ejecta and dense circumstellar material. Dust may be
present in the unshocked ejecta; the cool, dense shell (CDS) between
the shocks in the interaction region; or in the circumstellar medium
(CSM). We present and model new optical and infrared photometry and
spectroscopy of SN 2010jl from 82 to 1367 days since explosion. We
evaluate the photometric and spectroscopic evolution using the
radiative transfer codes MOCASSIN and DAMOCLES, respectively. We
propose an interaction scenario and investigate the resulting dust
formation scenarios and dust masses. We find that SN 2010jl has been
continuously forming dust based on the evolution of its infrared
emission and optical spectra. There is evidence for preexisting dust
in the CSM as well as new dust formation in the CDS and/or ejecta. We
estimate that 0.005-0.01M☉ of predominantly carbon dust grains
has formed in SN 2010jl by ∼1400 days post-outburst.
Description:
The first detection of SN 2010jl was from prediscovery images obtained
on 2010 October 9.6 (Stoll+ 2011ApJ...730...34S 2011ApJ...730...34S). For this paper, we
adopt an explosion date of 2010 October 10.
New images and spectra of SN 2010jl were obtained over five epochs
with Gemini/GMOS-S (GS-2012A-Q-79, GS-2013A-Q-93, GS-2014A-Q-70,
GN-2016A-Q-85-31).
