SN 2020bij and four other Type IIP SNe with slow-rising light curves and high velocities are modeled with weak to no CSM interaction, suggesting a new subclass linked to confined CSM.

abstract
Gaia is the cornerstone mission of the European Space Agency. From late 2013 it will start collecting superb astrometric, photometric and spectroscopic data for around a billion of stars of our Galaxy. While surveying the whole sky down to V=20mag Gaia will be detecting transients and anomalous behaviour of objects, providing near-real-time alerts to the entire astronomical community. Gaia should detected about 6000 supernovae, 1000 microlensing events and many other interesting types of transients. Thanks to its on-board low-dispersion spectrograph the classification of transients will be robust, assuring low false-alert rate. We describe the operation of the Photometric Science Alerts system, outline the scientific possibilities and conclude with an invitation to collaborate in the ground-based follow-up Gaia alerts during the early months of the mission when the outcome of the alerting pipeline needs to be verified.

SN 2020bij and a Possible Slow-Rise High-Velocity Subclass of Type IIP Supernovae
SN 2020bij and four other Type IIP SNe with slow-rising light curves and high velocities are modeled with weak to no CSM interaction, suggesting a new subclass linked to confined CSM.
