Failed jet breakout in the metal-poor broad-lined type Ic supernova 2026gzf

Antonio Martin-Carrillo, Christina C. Thöne, James K. Leung, Gregory Corcoran et autres

A long-standing question in the death of massive stars is the role of relativistic jets. While many gamma-ray bursts and some fast X-ray transients seem to be associated with broad-lined type Ic supernovae, the opposite is not true. The lack of observable …

The History Goes On: Century Long Study of Romano’s Star

Olga Maryeva, Roberto F. Viotti, Gloria Koenigsberger, Massimo Calabresi et autres

GR 290 (M 33 V0532 = Romano’s Star) is a unique variable star in the M33 galaxy, which simultaneously displays variability typical for luminous blue variable (LBV) stars and physical parameters typical for nitrogen-rich Wolf-Rayet (WR) stars (WN). As of now, GR …

Total eclipse of the heart: the AM CVn Gaia14aae/ASSASN-14cn

Heather C. Campbell, Thomas R. Marsh, M. Fraser, S. T. Hodgkin et autres

We report the discovery and characterization of a deeply eclipsing AM CVn-system, Gaia14aae (=ASSASN-14cn). Gaia14aae was identified independently by the All-Sky Automated Survey for Supernovae (ASAS-SN; Shappee et al.) and by the Gaia Science Alerts project, during two separate outbursts. A third …
