We present photometric and spectroscopic observations of the nearby ( D ≈ 28 Mpc) interacting supernova (SN) 2019esa, discovered within hours of explosion and serendipitously observed by the Transiting Exoplanet Survey Satellite ( TESS ). Early, high cadence light curves from both TESS and the DLT40 survey tightly constrain the time of explosion, and show a 30 day rise to maximum light followed by a near constant linear decline in luminosity. Optical spectroscopy over the first 40 days revealed…

Hydrogen-Rich Core-Collapse Supernovae
Hydrogen-rich core collapse supernovae, known as “Type II” supernovae, are the most common type of explosion realized in nature. They are defined by the presence of prominent hydrogen lines in their
Observational and Physical Classification of Supernovae
This chapter describes the current classification scheme of supernovae (SNe). This scheme has evolved over many decades and now includes numerous SN Types and sub-types. Many of these are universally
