Dust Without Na I D Trace: The Case of Highly Attenuated Type Ib SN 2024vjc
Javier Silva-Farfán, Keiichi Maeda, Andrea Pastorello +19
Understanding dust attenuation toward extragalactic transients is critical for recovering their intrinsic properties and probing the local environments of distant galaxies. A popul…
Late-time evolution of the interacting stripped-envelope supernova 2017dio
C. Humina, C. P. Gutiérrez, H. Kuncarayakti +14
The discovery of stripped-envelope supernovae (SNe) interacting with dense circumstellar medium (CSM) challenges our current understanding of massive star evolution. We present lat…
The local ultraviolet signature of Type Ia supernova environments from HST and MUSE
LluÃs Galbany, Cullen Abelson, Alaa Alburai +17
(Abridged.) The local environment of a Type Ia supernova (SN Ia) encodes information on progenitor age, star formation, dust, and chemical enrichment that may influence both its li…
Decadal pre-explosion activity and circumstellar interaction in a supernova
Ting-Wan Chen, Amar Aryan, Sheng Yang +52
When a massive star explodes as a supernova, crucial information about its immediate environment is lost within hours. Here we report rapid optical observations from Lulin Observat…
The SOXS Spectrograph Instrument Control Software
Davide Ricci, Bernardo Salasnich, Andrea Baruffolo +51
SOXS (Son Of X-Shooter) is a new spectrograph for the European Southern Observatory (ESO), recently installed at the New Technology Telescope (NTT) at the La Silla Observatory, Chi…
Massive stars exploding in a He-rich circumstellar medium XII. SN 2024acyl: A fast, linearly declining Type Ibn supernova with early flash-ionisation features
Y. -Z. Cai, A. Pastorello, K. Maeda +63
We present a photometric and spectroscopic analysis of the Type Ibn supernova (SN) 2024acyl. It rises to an absolute magnitude peak of about -17.58 mag in 10.6 days, and displays a…
