TOI-1333Ab is on a well-aligned orbit. An aligned hot Jupiter around an F-type star with a mutually inclined stellar companion

E. Knudstrup, M. L. Marcussen, S. H. Albrecht +2

Spin-orbit obliquity measurements of hot-Jupiter systems constrain giant planet migration and tidal evolution. In binary systems, combining stellar obliquities with the orbit-orbit…

A JWST/MIRI analysis of the ice distribution and PAH emission in the protoplanetary disk HH 48 NE

J. A. Sturm, M. K. McClure, D. Harsono +18

Ice-coated dust grains provide the main reservoir of volatiles that play an important role in planet formation processes and may become incorporated into planetary atmospheres. How…

Ejected Particles after Impact Splash on Mars: Aggregates and Aerodynamics

Tim Becker, Jens Teiser, Teresa Jardiel +6

Our earlier laboratory measurements showed that low-velocity sand impacts release fine <5 μm dust from a Martian simulant soil. This dust will become airborne in the Martian atmosp…

Company for the ultra-high density, ultra-short period sub-Earth GJ 367 b: discovery of two additional low-mass planets at 11.5 and 34 days

Elisa Goffo, Davide Gandolfi, Jo Ann Egger +38

GJ 367 is a bright (V 10.2) M1 V star that has been recently found to host a transiting ultra-short period sub-Earth on a 7.7 hr orbit. With the aim of improving the plan…
