SN 2020bij and a Possible Slow-Rise High-Velocity Subclass of Type IIP Supernovae
Sondos Mohsen-Tanev, Iair Arcavi, Shahar Bracha +17
Mapping how the explosion properties of Type II supernovae (SNe II) relate to the properties of their progenitors can provide strong constraints for understanding the final evoluti…
SN 2024gy: Multi-epoch Spectroscopic Features Suggestive of Delayed Detonation in a Type Ia Supernova
Liping Li, Zhenyu Wang, Jialian Liu +28
We present photometric and spectroscopic observations of SN 2024gy, a Type Ia supernova (SN Ia) exhibiting high-velocity features (HVFs) in its early-time spectra. This SN reaches…
A long-lasting eruption heralds SN 2023ldh, a clone of SN 2009ip
A. Pastorello, A. Reguitti, L. Tartaglia +46
We discuss the results of the spectroscopic and photometric monitoring of the type IIn supernova (SN) 2023ldh. Survey archive data show that the SN progenitor experienced some erra…
SN 2021hpr: A Normal Type Ia Supernova Showing Excess Emission in the Early Rising Phase
Abdusamatjan Iskandar, Xiaofeng Wang, Ali Esamdin +37
We present extensive optical observations of a nearby Type Ia supernova (SN Ia), SN 2021hpr, located in the spiral galaxy NGC 3147 at a distance of 45 Mpc. Our observations…
Evidence of weak circumstellar medium interaction in the Type II SN 2023axu
Manisha Shrestha, Jeniveve Pearson, Samuel Wyatt +34
We present high-cadence photometric and spectroscopic observations of SN~2023axu, a classical Type II supernova with an absolute -band peak magnitude of mag. SN~…
The Early Light Curve of SN 2023bee: Constraining Type Ia Supernova Progenitors the Apian Way
Griffin Hosseinzadeh, David J. Sand, Sumit K. Sarbadhicary +39
We present very early photometric and spectroscopic observations of the Type Ia supernova (SN Ia) 2023bee, starting about 8 hr after the explosion, which reveal a strong excess in…
Short-Lived Circumstellar Interaction in the Low-Luminosity Type IIP SN 2016bkv
Griffin Hosseinzadeh, Stefano Valenti, Curtis McCully +12
While interaction with circumstellar material is known to play an important role in Type IIn supernovae (SNe), analyses of the more common SNe IIP and IIL have not traditionally in…
iPTF15eqv: Multi-wavelength Exposé of a Peculiar Calcium-rich Transient
D. Milisavljevic, D. Patnaude, J. Raymond +15
The progenitor systems of the class of "Ca-rich transients" is a key open issue in time domain astrophysics. These intriguing objects exhibit unusually strong calcium line emission…
