Abstract:
We present high-cadence UV, optical, and near-infrared data on the
luminous Type II-P supernova SN2017gmr from hours after discovery
through the first 180 days. SN 2017gmr does not show signs of narrow,
high-ionization emission lines in the early optical spectra, yet the
optical light-curve evolution suggests that an extra energy source
from circumstellar medium (CSM) interaction must be present for at
least 2 days after explosion. Modeling of the early light curve
indicates a ∼500R☉ progenitor radius, consistent with a rather
compact red supergiant, and late-time luminosities indicate that up to
0.130±0.026M☉ of 56Ni are present, if the light curve is
solely powered by radioactive decay, although the 56Ni mass may be
lower if CSM interaction contributes to the post-plateau luminosity.
Prominent multipeaked emission lines of Hα and [OI] emerge
after day 154, as a result of either an asymmetric explosion or
asymmetries in the CSM. The lack of narrow lines within the first 2
days of explosion in the likely presence of CSM interaction may be an
example of close, dense, asymmetric CSM that is quickly enveloped by
the spherical supernova ejecta.
Description:
A comprehensive optical and near-infrared (NIR) data set has been
collected on SN2017gmr, with several major Super Nova (SN)
collaborations contributing data. These include the Las Cumbres
Observatory's Global Supernova Project, the NOT (Nordic Optical
Telescope) Un-biased Transient Survey51 (NUTS), the Public ESO
Spectroscopic Survey for Transient Objects (ePESSTO), the Texas
Supernova Spectroscopic Survey (TS3), and the Tsinghua Supernova
Project.
The second section of the article briefly lists the
instruments/telescopes used in obtaining data for SN2017gmr.
