The hydrogen-free circumstellar interaction in the Type Ib supernova 2021efd: A clue to the mechanism of the helium-layer stripping
N. Pyykkinen, T. Nagao, H. Kuncarayakti +27
Stripped-envelope supernovae (SESNe), including Type IIb, Ib, and Ic supernovae (SNe), originate from the explosions of massive stars whose outer envelopes have been largely remove…
The ANDICAM-SOFI Near-infrared and Optical type Ia Supernova (ASNOS) sample: Description and data release
Kim Phan, Lluís Galbany, Tomás E. Müller-Bravo +13
Type Ia supernovae (SNe Ia) provide the most robust means of measuring extragalactic distances. While most of the effort has focused on increasing the number of SNe Ia observed in…
The broad-lined type Ic supernova 2020lao experienced an energetic explosion with no central-engine signatures
M. D. Stritzinger, T. J. Moriya, S. Bose +18
We present infant-phase observations of the SN Ic-BL 2020lao, including optical spectroscopy beginning 48 hrs after explosion. The explosion time was constrained by power-law fits…
The Type Ia Supernova 2021hem: A 2003fg-like Event in an Apparently Hostless Environment
Subhash Bose, M. D. Stritzinger, A. Malmgaard +25
We report observations of Type Ia SN 2021hem, located in an apparently hostless environment. With a peak absolute B-band magnitude of -19.96 mag, and a lack of secondary maximum in…
Massive stars exploding in a He-rich circumstellar medium XII. SN 2024acyl: A fast, linearly declining Type Ibn supernova with early flash-ionisation features
Y. -Z. Cai, A. Pastorello, K. Maeda +63
We present a photometric and spectroscopic analysis of the Type Ibn supernova (SN) 2024acyl. It rises to an absolute magnitude peak of about -17.58 mag in 10.6 days, and displays a…
SN 2018is: a low-luminosity Type IIP supernova with narrow hydrogen emission lines at early phases
R. Dastidar, K. Misra, S. Valenti +31
We present a comprehensive photometric and spectroscopic study of the Type IIP SN 2018is. The -band luminosity and the expansion velocity at 50 days post-explosion are 15.1$\…
Expanding the parameter space of 2002es-like type Ia supernovae: on the underluminous ASASSN-20jq / SN 2020qxp
Subhash Bose, Maximilian D. Stritzinger, Chris Ashall +23
We present optical photometric and spectroscopic observations of the peculiar Type Ia supernova ASASSN-20jq/SN 2020qxp. It is a low-luminosity object with a peak absolute magnitude…
