Query: Photometric and polarimetric observations of fast declining Type II
  supernovae 2013hj and 2014G   We present broadband photometric and polarimetric observations of two type II
supernovae (SNe) 2013hj and 2014G. SN 2014G is a spectroscopically classified
type IIL event, which we also confirm photometrically as its light curve show
characteristic features (plateau slope of 2.55 mag (100 d)$ ^{-1} $ in V-band
and duration of $ \sim77 $d) of a generic IIL SN. On the other hand SN 2013hj
also shows high plateau decline rate of $ 1.5 $ mag (100 d)$ ^{-1} $ in V-band,
similar to SNe IIL, but marginally lower than SNe IIL template light curves.
Our high cadence photometric observations of SNe 2013hj and 2014G enables us to
cover all characteristic phases up to radioactive tail of optical light curves.
Broadband polarimetric observations reveal some polarization in SN 2013hj with
subtle enhancement as SN evolves towards plateau end, however the polarization
angle remains constant throughout the evolution. This characteristic is
consistent with the idea that the evolving SN with recombining hydrogen
envelope is slowly revealing more asymmetric central region of explosion.
Modelling of bolometric light curve yields a progenitor mass of $ \sim11
$M$_{\odot}$ with a radius of $ \sim700 $R$_{\odot}$ for SN 2013hj, while for
SN 2014G model estimated progenitor mass is $ \sim9 $M$_{\odot}$ with a radius
of $ \sim630 $R$_{\odot}$, both having a typical energy budget of $
\sim2\times10^{51} $ erg.
