A massive, energetic model for the luminous transitional Type Ib/IIb SN 2020cpg

Autor: J Teffs, P A Mazzali, K Medler, S Hachinger

Publikováno v: Monthly Notices of the Royal Astronomical Society. 517:5678-5686

Using a combined spectral and light-curve modelling approach, we fit a massive and energetic explosion model to the luminous Type Ib/IIb SN 2020cpg. This model has an ejected mass of ∼(7 ± 2) M⊙ with a final explosion energy of ∼(6 ± 1) × 10

How much H and He is ‘hidden’ in SNe Ib/c? – II. Intermediate-mass objects: a 22 M⊙ progenitor case study

Stripped envelope supernovae are a sub-class of core collapse supernovae showing several stages of H/He shell stripping that determines the class: H-free/He-poor SNe are classified as Type Ic, H-poor/He-rich are Type Ib, and H/He-rich are Type IIb. S

Observations and Spectral Modelling of the Narrow-Lined Type Ic SN 2017ein

Autor: S. J. Prentice, J. Teffs, C. Ashall, Paolo A. Mazzali

SN 2017ein is a narrow-lined Type Ic SN that was found to share a location with a point-like source in the face on spiral galaxy NGC 3938 in pre-supernova images, making SN 2017ein the first credible detection of a Type Ic progenitor. Results in the
