SN 2023fyq: direct detection of a Type Ibn supernova progenitor and its multi-wavelength environmental constraints
Xinyi Hong, Ning-Chen Sun, Yali Shao +9
Context. Type Ibn supernovae (SNe) are characterized by narrow helium emission lines arising from ejecta-circumstellar medium interaction, yet their progenitors remain debated, wit…
A statistical study of the environmental age of core-collapse supernovae based on VLT/MUSE integral-field-unit spectroscopy
Qiang Xi, Ning-Chen Sun, Yihan Zhao +13
We aim to understand the progenitor channels of CCSNe via a statistical study of the ages of their environments. We compiled a large and minimally biased sample of 128 CCSNe discov…
Direct Detection of Type II-P Supernova Progenitors with the and CSST Surveys
Junjie Wu, Ning-Chen Sun, Zexi Niu +14
Identifying and characterizing supernova (SN) progenitor stars remains a central yet difficult goal in SN research, limited by archival images lacking sufficient depth or spatial r…
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…
Constraining the progenitor of the nearby Type II-P SN 2024ggi with environmental analysis
Xinyi Hong, Ning-Chen Sun, Zexi Niu +3
The progenitors of Type II-P supernovae (SN) have been confirmed to be red supergiants. However, the upper mass limit of the directly probed progenitors is much lower than that pre…
