Spin-Orbit Geometry of AU Mic b and c from Back-to-Back Transits Observed Contemporaneously with Magellan PFS, LCOGT, and CHEOPS
Zitao Lin, Gyula M. Szabó, Krzysztof Sz. ZieliÅski +37
Young planets offer a unique window into the early stages of planetary evolution. AU Mic is one of the nearest (9.8 pc) pre-main sequence stars (~20 Myr), hosting two transiting Ne…
The GAPS programme at TNG: LXXVI. TOI-1533: a compact system hosting a super-Neptune-mass pair with disparate radii
G. Mantovan, V. Nascimbeni, S. Desidera +49
The present-day architecture of planetary systems contains information about their formation and migration histories. The origin of hot Jupiters (HJs, P 10 d, $R_{\rm p}…
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 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…
The GAPS Programme at the TNG: LXX. TOI-5734b: A hot sub-Neptune orbiting a relatively young K dwarf with an Earth-like density
S. Filomeno, T. Trifonov, M. Damasso +40
Increasing interest in young exoplanets is leading to a growing effort to understand the formation and evolutionary processes responsible for their different architectures. One int…
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…
