Formation and Diagnostic Use of Carbon Lines in Stripped-Envelope Supernovae
Stan Barmentloo, Anders Jerkstrand
Carbon is one of the main end products of nucleosynthesis in massive stars. In this work, we study the emission signatures of carbon in spectra of stripped envelope supernovae (SES…

Luminous Type II Short-Plateau SN 2023ufx: Asymmetric Explosion of a Partially-Stripped Massive Progenitor
Aravind P. Ravi, Stefano Valenti, Yize Dong +34
We present supernova (SN) 2023ufx, a unique Type IIP SN with the shortest known plateau duration ( 47 days), a luminous V-band peak ( = 18.42 0…
