Ejecta masses in Type Ia Supernovae -- Implications for the Progenitor and the Explosion Scenario

Zsófia Bora, Réka Könyves-Tóth, József Vinkó +35

The progenitor system(s) as well as the explosion mechanism(s) of thermonuclear (Type Ia) supernovae are long-standing issues in astrophysics. Here we present ejecta masses and oth…

AT2023vto: An Exceptionally Luminous Helium Tidal Disruption Event from a Massive Star

Harsh Kumar, Edo Berger, Daichi Hiramatsu +10

We present optical/UV observations and the spectroscopic classification of the transient AT2023vto as a tidal disruption event (TDE) at z = 0.4846. The spectrum is dominated by a b…

The Type I Superluminous Supernova Catalog I: Light Curve Properties, Models, and Catalog Description

Sebastian Gomez, Matt Nicholl, Edo Berger +25

We present the most comprehensive catalog to date of Type I Superluminous Supernovae (SLSNe), a class of stripped envelope supernovae (SNe) characterized by exceptionally high lumi…

Final Moments II: Observational Properties and Physical Modeling of CSM-Interacting Type II Supernovae

W. V. Jacobson-Galán, L. Dessart, K. W. Davis +52

We present ultraviolet/optical/near-infrared observations and modeling of Type II supernovae (SNe II) whose early-time ( days) spectra show transient, narrow emission lines…

SN 2019nyk: A rapidly declining Type II supernova with early interaction signatures

Raya Dastidar, Giuliano Pignata, Naveen Dukiya +9

We present an optical photometric and spectroscopic analysis of the fast-declining hydrogen-rich Type II supernova (SN) 2019nyk. The light curve properties of SN 2019nyk align well…

A Robust Light-Curve Diagnostic for Electron-Capture Supernovae and Low-Mass Fe-Core-Collapse Supernovae

Masato Sato, Nozomu Tominaga, Sergei I. Blinnikov +3

Core-collapse supernovae (CCSNe) are the terminal explosions of massive stars. While most massive stars explode as iron-core-collapse supernovae (FeCCSNe), slightly less massive st…
