Low-Luminosity Type IIP Supernovae from the Zwicky Transient Facility Census of the Local Universe. I: Luminosity Function, Volumetric Rate

Kaustav K. Das, Mansi M. Kasliwal, Christoffer Fremling +51

We present the luminosity function and volumetric rate of a sample of Type IIP supernovae (SNe) from the Zwicky Transient Facility Census of the Local Universe survey (CLU). This i…

Disappearance of a massive star in the Andromeda Galaxy due to formation of a black hole

Kishalay De, Morgan MacLeod, Jacob E. Jencson +11

When a massive star reaches the end of its lifetime, its core collapses and releases neutrinos that drive a shock into the outer layers (stellar envelope). A sufficiently strong sh…

Revealing a main-sequence star that consumed a planet with JWST

Ryan M. Lau, Jacob E. Jencson, Colette Salyk +8

The subluminous red nova (SLRN) ZTF SLRN-2020 is the most compelling direct detection of a planet being consumed by its host star, a scenario known as a planetary engulfment event.…
