Researchers have detected SO and SO2 for the first time in an early-type evolved star; these results suggest that B[e]supergiants could be useful for studying sulfur chemistry under extreme radiation conditions.

Some systems in the Habitable Worlds Observatory (HWO) Exoplanet Exploration Program (ExEP) Mission Star List have more than a 50% chance of hosting a temperate terrestrial exoplanet.

More than half of solar magnetic flux appears to emerge in three bands, two of which rotate faster than the Carrington rate; this finding suggests a connection between surface flux and interior dynamical processes.

Researchers have identified six new candidate circumbinary disk systems, potentially greatly increasing the number of known systems of this type; these system exhibit deep and prolonged dimming episodes.

Ultra-hot Jupiter KELT-9b possesses an outflow with a mass-loss rate above 1013 g s-1 — one of the highest mass-loss rates measured for a gaseous exoplanet — and a diagnostic hydrogen Balmer line from its dayside.
