Panchromatic JWST Observations and Models of the Dim Type Iax Supernova 2024vjm at 200 days

E Baron, J. M. DerKacy, C. Ashall +23

We report JWST spectra and photometry of the underluminous SN Iax 2024vjm obtained 202.8 restframe days post-explosion. The spectrum exhibits a rich set of forbidden lines from low…

SN 2025aico: Early observations of a faint Type IIb supernova with a low-mass envelope

J. -W. Zhao, A. Pastorello, B. Kumar +45

We aimed to investigate the physical properties and the underlying explosion mechanisms of the Type IIb SN 2025aico. Through a comprehensive analysis of early-phase optical light c…

The type Ia supernova 2023vjh: a peculiar 1991bg-like SN with unusually faint light curves

M. Kopsacheili, L. Galbany, G. Folatelli +32

We present observations of the 1991bg-like type Ia supernova (SN) 2023vjh, associated with the elliptical galaxy MCG+04-10-013. Its light-curve shape parameters ($Δm_{15}(B)=1.89…

JWST Medium-Resolution Infrared Spectroscopy of SN 2022acko: Tracing Molecule Formation in the Nebular Phase

K. Medler, T. Mera, C. Ashall +28

The Type II supernova (SN II) SN 2022acko was the first to be spectroscopically observed by the James Webb Space Telescope (). Here, we analyze SN 2022acko's second…

The local ultraviolet signature of Type Ia supernova environments from HST and MUSE

Lluís Galbany, Lluís Galbany, Cullen Abelson +22

The local environment of a Type Ia supernova (SN~Ia) traces the local stellar-population age (a statistical proxy for the progenitor age), star formation, dust, and chemical enrich…

Decadal pre-explosion activity and circumstellar interaction in a supernova

Ting-Wan Chen, Amar Aryan, Sheng Yang +52

When a massive star explodes as a supernova, crucial information about its immediate environment is lost within hours. Here we report rapid optical observations from Lulin Observat…
