Low-luminosity jets and winds from supernovae or tidal disruption events are the only remaining explanation for the Fermi/eROSITA bubbles, according to recent research.
Maria C. Schutte et al 2023 AJ 166 92
A new modeling method allows for researchers to determine the temperature of a starspot from just one passage of an exoplanet over the spot, as demonstrated by modeling of the K dwarf HAT-P-11.
S. J. Bromley et al 2023 ApJS 268 22
New calculations of collisional cross sections of certain elements can improve our molding and our understanding of kilonovae, the explosions caused by colliding neutron stars.
