On the fate of the secondary white dwarf in double-degenerate double-detonation Type Ia supernovae -- II. 3D synthetic observables
J. M. Pollin, S. A. Sim, R. Pakmor +5
A leading model for Type Ia supernovae involves the double-detonation of a sub-Chandrasekhar mass white dwarf. Double-detonations arise when a surface helium shell detonation gener…
SN 2021dbg: A Luminous Type IIP-IIL Supernova Exploding from a Massive Star with a Layered Shell
Zeyi Zhao, Jujia Zhang, Liping Li +9
We present extensive observations and analysis of supernova (SN) 2021dbg, utilizing optical photometry and spectroscopy. For approximately 385 days following the explosion, SN 2021…
Discovery and Extensive Follow-Up of SN 2024ggi, a nearby type IIP supernova in NGC 3621
Ting-Wan Chen, Sheng Yang, Shubham Srivastav +45
We present the discovery and early observations of the nearby Type II supernova (SN) 2024ggi in NGC 3621 at 6.64 +/- 0.3 Mpc. The SN was caught 5.8 (+1.9 -2.9) hours after its expl…
Including a Luminous Central Remnant in Radiative Transfer Simulations for Type Iax Supernovae
F. P. Callan, S. A. Sim, C. E. Collins +6
Type Iax supernovae (SNe Iax) are proposed to arise from deflagrations of Chandrasekhar mass white dwarfs (WDs). Previous deflagration simulations have achieved good agreement with…
The metamorphosis of the Type Ib SN 2019yvr: late-time interaction
Lucía Ferrari, Gastón Folatelli, Hanindyo Kuncarayakti +32
We present observational evidence of late-time interaction between the ejecta of the hydrogen-poor Type Ib supernova (SN) 2019yvr and hydrogen-rich circumstellar material (CSM), si…
SN 2020udy: A new piece of the homogeneous bright group in the diverse Iax subclass
Mridweeka Singh, Devendra K. Sahu, Barnabas Barna +23
We present optical observations and analysis of a bright type Iax SN~2020udy hosted by NGC 0812. The light curve evolution of SN~2020udy is similar to other bright Iax SNe. Analyti…
