Query: Numerical Modeling of the Early Light Curves of Type IIP Supernovae   The early rise of Type IIP supernovae (SN IIP) provides important information
for constraining the properties of their progenitors. This can in turn be
compared to pre-explosion imaging constraints and stellar models to develop a
more complete picture of how massive stars evolve and end their lives. Using
the SuperNova Explosion Code (SNEC), we model the first 40 days of SNe IIP to
better understand what constraints can be derived from their early light
curves. We use two sets of red supergiant progenitor models with zero-age main
sequence masses in the range between 9 Msol and 20 Msol. We find that the early
properties of the light curve depend most sensitively on the radius of the
progenitor, and thus provide a relation between the g-band rise time and the
radius at the time of explosion. This relation will be useful for deriving
constraints on progenitors from future observations, especially in cases where
detailed modeling of the entire rise is not practical. When comparing to
observed rise times, the radii we find are a factor of a few larger than
previous semi-analytic derivations and generally in better agreement with what
is found with current stellar evolution calculations.
