Laboratory studies show that salt deliquescence — the process of something becoming a liquid — is likely slow on Mars, which suggests that only small amounts of brines on the planet’s surface could form this way.

New calculations predict the luminosity and spectrum that result from a shock wave crossing the edge of a star, as might occur during a supernova explosion.

Colin Littlefield et al 2023 ApJL 943 L24

Researchers have discovered a highly magnetized white dwarf that, despite theoretical predictions otherwise, has not synchronized its rotational frequency to the orbital frequency of the binary system it belongs to.

Chemically peculiar barium stars, first discovered in the 1950s, show enhanced abundances of s-process (slow neutron capture) elements, which might result from pollution from a binary companion.

The X-ray and radio emission characteristics of a young magnetar — a highly magnetized neutron star — can tell us about the object’s neighborhood, including the diffuse supernova remnant that surrounds it.

Ryoko Ishioka et al 2023 ApJS 265 18

A survey of 92 unclassified objects turned up 42 young stellar objects and 50 protoplanetary nebulae, evolved stars, and dust-shrouded stars, plus a few objects that still defy classification.
