According to new modeling, New Horizons’s crater counts on Pluto’s moon Charon match the frequencies expected from collisional cascades of solids with bulk strength intermediate between weak and normal ice.

New 3D simulations show that large black holes ejected from galactic nuclei could be spotted by ALMA and other facilities as the black holes wander the outskirts of galaxies, slowly accreting matter.

A new study of abundances indicates that, in general, plankton, Earth, and Mars are phosphorous-rich compared with nearby stars, but there’s a dearth of phosphorous abundance data, making it difficult to draw conclusions.

The light curves of 1000 TESS objects of interest reveal 163 targets with rotation signatures, 131 of which have unambiguous rotation periods; this sample allows us to better understand stellar rotation.

The superoutburst duration of SDSS J080710+485259 exceeds the ~2 month viscous time of its accretion disk by a factor of about 5, but irradiation of the donor star might explain this unusual behavior.
Jayanta Dutta et al 2020 ApJ 901 16
Modeling suggests that certain population III protostars ejected from their host clusters early in the universe’s evolution may survive to the present day on the main sequence, and could even be found in the Milky Way.
