SN 2025coe: A Multiple-Peaked Calcium-Strong Transient from A White-Dwarf Progenitor
Chun Chen, Ning-Chen Sun, Qiang Xi +25
SN 2025coe is a calcium-strong transient located at an extremely large projected offset 39.3 kpc from the center of its host, the nearby early-type galaxy NGC 3277 at a dista…
SN 2024aecx: a fast-evolving Type IIb supernova with a prominent shock-cooling peak
Qiang Xi, Ning-Chen Sun, David Aguado +36
SN 2024aecx is a nearby (11 Mpc) Type IIb SN discovered within 1 d after explosion. In this paper we report high-cadence photometric (typically 0.51 day) and spec…
A late-time view of the progenitor candidates of the Type II-P SN 2009ib and SN 2012ec
Yi-Han Zhao, Xinyi Hong, Ning-Chen Sun +3
The progenitors of Type II-P supernovae (SNe) are generally considered to be red supergiants; however, the so-called "red supergiant problem" indicates that a deeper investigation…
An environmental analysis of supernova iPTF13bvn with HST and MUSE
Adam J. Singleton, Justyn R. Maund, Ning-Chen Sun
Searches for supernovae (SNe) progenitors have relied on a direct detection of the star in fortuitous pre-explosion images. We propose an alternative method, using a combination of…
Discovery of a variable yellow supergiant progenitor for the Type IIb SN 2024abfo
Zexi Niu, Ning-Chen Sun, Justyn R. Maund +4
We report the discovery of a progenitor candidate for the Type~IIb SN2024abfo using multi-epoch pre-explosion images from the Hubble Space Telescope and the Dark Energy Camera Lega…
