Stellar impact on exoplanetary atmospheric evolution and habitability
AntÃgona Segura, Manuel Güdel, Konstantin Herbst +4
The paper reviews how stellar irradiation, evolution, and activity affect atmospheric escape, climate, and habitability of exoplanets.
JWST/MIRI Detection of Molecular H Winds from an Edge-on Class II Source HV Tau C
Vinod Chandra Pathak, P. Manoj, Himanshu Tyagi +14
The paper uses JWST/MIRI mid‑infrared spectroscopy to detect and characterize a wide‑angled molecular hydrogen wind from the edge‑on Class II protoplanetary disk HV Tau C, measurin…
An Ultra-Short Period Super-Earth and a Sub-Neptune Orbiting the K dwarf TOI-4311
Yoshi Nike Emilia Eschen, Thomas G. Wilson, Andrew Collier Cameron +95
We report the discovery and characterisation of the multi-planetary system around TOI-4311, a K dwarf kinematically between the Galactic thick disk and Hercules stream. TOI-4311 ho…
The impact of electron precipitation on Earth's thermospheric NO production and the drag of LEO satellites
M. Scherf, S. Krauss, G. Tsurikov +6
We investigate the response of space weather events on Earth's upper atmosphere over the polar regions by studying their effect on the drag of the CHAMP and GRACE satellites. Incre…
Gas-depleted planet formation occurred in the four-planet system around the red dwarf LHS 1903
Thomas G. Wilson, Anna M. Simpson, Andrew Collier Cameron +173
Small exoplanet radii show two populations, referred to as super-Earths and sub-Neptunes, separated by a gap known as the radius valley. This may be produced by the removal of atmo…
Is the high-energy environment of K2-18b special?
S. Rukdee, M. Güdel, I. ViloviÄ +7
K2-18b lies near the radius valley that separates super-Earths and sub-Neptunes, marking a key transitional regime in planetary and atmospheric composition. The system offers a val…
