SN 2024cld: unveiling the complex mass-loss histories of evolved supergiant progenitors to core collapse supernovae

T. L. Killestein, M. Pursiainen, R. Kotak +52

Pre-explosion mass loss in supernova (SN) progenitors is a crucial unknown factor in stellar evolution, yet has been illuminated recently by the diverse zoo of interacting transien…

SN 2024hpj: A perspective on SN 2009ip-like events

I. Salmaso, A. Pastorello, E. Borsato +25

Supernovae (SNe) IIn are terminal explosions of massive stars that are surrounded by a dense circumstellar medium (CSM). Among SNe IIn, a notable subset is the SN 2009ip-like, whic…

SVOM GRB 250314A at z 7.3: an exploding star in the era of reionization

B. Cordier, J. Y. Wei, N. R. Tanvir +103

Most long Gamma-ray bursts originate from a rare type of massive stellar explosion. Their afterglows, while rapidly fading, can be initially extremely luminous at optical/near-infr…

On the diversity of strongly-interacting Type IIn supernovae

I. Salmaso, E. Cappellaro, L. Tartaglia +29

Massive stars experience strong mass-loss, producing a dense, H-rich circumstellar medium (CSM). After the explosion, the collision and continued interaction of the supernova (SN)…
