RINGO3 polarimetry of very young ZTF supernovae
J. R. Maund, Y. Yang, I. A. Steele +13
The early phases of the observed evolution of the supernovae (SNe) are expected to be dominated by the shock breakout and ``flash" ionization of the surrounding circumstellar mediu…
A WC/WO star exploding within an expanding carbon-oxygen-neon nebula
A. Gal-Yam, R. Bruch, S. Schulze +46
The final explosive fate of massive stars, and the nature of the compact remnants they leave behind (black holes and neutron stars), are major open questions in astrophysics. Many…
A highly magnetised and rapidly rotating white dwarf as small as the Moon
Ilaria Caiazzo, Kevin B. Burdge, James Fuller +15
White dwarfs represent the last stage of evolution of stars with mass less than about eight times that of the Sun and, like other stars, are often found in binaries. If the orbital…
Discovery and confirmation of the shortest gamma ray burst from a collapsar
Tomas Ahumada, Leo P. Singer, Shreya Anand +54
Gamma-ray bursts (GRBs) are among the brightest and most energetic events in the universe. The duration and hardness distribution of GRBs has two clusters, now understood to reflec…
