Kento Masuda, Hajime Kawahara, David W. Latham +4
The authors report the discovery of a 0.2 M⊙ white dwarf in a wide (≈1.3 au) eccentric orbit around a Sun-like star, identified through self‑lensing events in Kepler data and confi…
New Regimes in the Observation of Core-Collapse Supernovae
Maryam Modjaz, Claudia P. Gutierrez, Iair Arcavi
The paper reviews recent observational advances that enable large statistical studies and early-time measurements of core‑collapse supernovae, helping to link explosion types to pr…
Observational Properties of Thermonuclear Supernovae
Saurabh W. Jha, Kate Maguire, Mark Sullivan
The paper reviews the observed characteristics of thermonuclear supernovae, especially Type Ia events, highlighting their role as standardizable distance indicators, sources of iro…
Stellar Physics with High-Resolution UV Spectropolarimetry
Julien Morin, Jean-Claude Bouret, Coralie Neiner +26
