SN 2022oqm: A Bright and Multi-peaked Calcium-rich Transient
S. Karthik Yadavalli, V. Ashley Villar, Luca Izzo +60
We present the photometric and spectroscopic evolution of SN 2022oqm, a nearby multi-peaked hydrogen- and helium-weak calcium-rich transient (CaRT). SN 2022oqm was detected 13.1 kp…
Type II-P Supernova Progenitor Star Initial Masses and SN 2020jfo: Direct Detection, Light Curve Properties, Nebular Spectroscopy, and Local Environment
Charles D. Kilpatrick, Luca Izzo, Rory O. Bentley +23
We present optical, ultraviolet, and infrared data of the type II supernova (SN II) 2020jfo at 14.5 Mpc. This wealth of multiwavelength data allows to compare different metrics com…
An Asymmetric Double-Degenerate Type Ia Supernova Explosion with a Surviving Companion Star
Matthew R. Siebert, Ryan J. Foley, Yossef Zenati +6
We present nebular spectroscopy of SN 2020hvf, a Type Ia supernova (SN Ia) with an early bump in its light curve. SN 2020hvf shares many spectroscopic and photometric similarities…
Observational properties of a bright type Iax SN 2018cni and a faint type Iax SN 2020kyg
Mridweeka Singh, Devendra. K. Sahu, Raya Dastidar +29
We present the optical photometric and spectroscopic analysis of two type Iax SNe 2018cni and 2020kyg. SN 2018cni is a bright type Iax SN (M = 17.810.21 mag) whe…
Flight of the Bumblebee: the Early Excess Flux of Type Ia Supernova 2023bee revealed by , and Young Supernova Experiment Observations
Qinan Wang, Armin Rest, Georgios Dimitriadis +41
We present high-cadence ultraviolet through near-infrared observations of the Type Ia supernova (SN Ia) 2023bee in NGC~2708 ( Mpc), finding excess flux in the first d…
The Renovated Thacher Observatory and First Science Results
Jonathan J. Swift, Karina Andersen, Toby Arculli +38
Located on the campus of the Thacher School in Southern California, the Thacher Observatory has a legacy of astronomy research and education that dates back to the late 1950's. In…
Weak Mass Loss from the Red Supergiant Progenitor of the Type II SN 2021yja
Griffin Hosseinzadeh, Charles D. Kilpatrick, Yize Dong +56
We present high-cadence optical, ultraviolet (UV), and near-infrared data of the nearby ( Mpc) Type II supernova (SN) 2021yja. Many Type II SNe show signs of interactio…
