Upside down: GJ3090 b the first retrograde exoplanet around an M dwarf detected with NIRPS

Y. Carteret, V. Bourrier, L. Parc +57

The angle between stellar spin axis and planetary orbital plane can provide key insights into the formation and dynamical evolution of planetary systems. In particular, this measur…

Kilometre-scale Jovian moon characterized for a potential JUICE flyby

Juan Luis Rizos, Jose Maria Gomez-Limon, Yucel Kilic +51

Jupiter's irregular satellites are thought to be relics of early Solar System planetesimals. However, their small sizes, large distances from Earth and close angular proximity to J…

Oxygen isotope fractionation in the Martian atmosphere induced by CO photolysis and O formation

Tatsuya Yoshida, Shohei Aoki, Hiromu Nakagawa +8

The enrichment of heavy isotopes of volatile elements in the Martian atmosphere indicates that Mars lost a large portion of its atmosphere through escape to space. Recent atmospher…

KRONOS I: The m JWST Transmission Spectrum of the 23 Myr V1298 Tau c

Matthew M. Murphy, Matthew C. Nixon, Adina D. Feinstein +16

While recent JWST observations of mature super-Earths and sub-Neptunes have frequently revealed featureless transmission spectra, their inflated progenitors offer a unique window i…

Dust and coma radicals in C/2024 E1 (Wierzchos): evolution of the activity

Irene Mariblanca-Escalona, Pedro J. Gutiérrez, Fernando Moreno +1

We present multi-epoch R-band imaging and long-slit spectroscopy of the dynamically new comet C/2024 E1 (Wierzchos) during its pre-perihelion phase, spanning heliocentric distances…
