Revisiting TOI-4438 and TOI-442 planetary systems with new observations from SPIRou and TESS

J. Serrano Bell, G. Hébrard, E. Martioli +26

The study re‑examines two M‑dwarf planetary systems, TOI‑4438 and TOI‑442, using new TESS transit data and high‑resolution near‑infrared spectroscopy from SPIRou, refining the plan…

Origin and characterization of super-Earths and sub-Neptunes

Léna Parc, Julia Venturini, François Bouchy +6

Super-Earths and sub-Neptunes represent the most common class of exoplanets discovered to date in our galaxy, yet they have no direct analogues in the Solar System. Since 2014, res…

The GAPS Programme at TNG. LXXIII. Confirmation of the hot sub-Neptune TOI-4602 b (HD 25295 b), a key target for future atmospheric characterization

C. Di Maio, S. Benatti, D. Locci +25

Precise mass and radius measurements of small, transitional exoplanets, such as super-Earths and sub-Neptunes, are essential to constrain their bulk density and formation history,…

Super-Earth masses and stellar abundances from NIRPS reveal tentative evidence for water-rich formation around M dwarfs

Drew Weisserman, Nicole Gromek, Ryan Cloutier +98

Tracing the compositional link between terrestrial super-Earths and their host stars provides clues to their dominant formation pathway. By constraining the stellar abundances of r…

The GAPS programme at TNG LXXI. A sub-Neptune suitable for atmospheric characterization in a multiplanet and mutually inclined system orbiting the bright K dwarf TOI-5789 (HIP 99452)

A. S. Bonomo, L. Naponiello, A. Sozzetti +37

Sub-Neptunes with planetary radii of are the most common planets around solar-type stars in short-period ( d) orbits. It is still unclear, howe…

A 34.6-day transiting sub-Neptune in the TOI-1422 planetary system

L. Naponiello, P. Leonardi, M. Damasso +9

TOI-1422 is a G2 V star ( mag) known to host a warm Neptune-sized planet, TOI-1422 b, with a mass and radius of about and , on a circular orbit…
