Existing observations appear to be in agreement with a model involving a rapidly rotating massive neutron star that launches a jet and an equatorial outflow that remains hidden for several years.
How CUTE — a cubesat has generated a new near-ultraviolet spectrum of the hottest known exoplanet, providing results consistent with those for other ultrahot Jupiters.
Modeling finds that dense crusts on small bodies are resilient against the Rayleigh–Taylor instability, suggesting that such crusts are likely to be common in our solar system.

A new catalog has led to the discovery of new asteroid families in the main asteroid belt; the total number of families in the asteroid belt now sits at 274.
Modeling suggests that the spectrum of NGC 5907 ULX1 is shaped by a magnetosphere with an asymmetric shape around the magnetic axis and hotter regions close to the magnetic pole.
New research disfavors the possibility that the gravitational wave event GW 190425 is associated with the fast radio burst FRB 20190425A, which was recently found to have arisen from the galaxy UGC 10667.
