The TOI-1117 Multi-planetary System: 3 sub-Neptunes, 1 in both the Neptunian Desert and Radius Valley

Isobel S. Lockley, David J. Armstrong, Jorge Fernández Fernández +33

We present the discovery of three sub-Neptune planets around TOI-1117, a Sun-like star with mass , radius , age Gyr and ef…

TOI-5005 b: A super-Neptune in the savanna near the ridge

A. Castro-González, J. Lillo-Box, D. J. Armstrong +38

The Neptunian desert and savanna have recently been found to be separated by a ridge, an overdensity of planets in the period range of 3-5 days. These features are thought…

TOI-512: Super-Earth transiting a K-type star discovered by TESS and ESPRESSO

J. Rodrigues, S. C. Barros, N. C. Santos +38

One of the goals of the ESPRESSO guaranteed time observations (GTOs) at the ESO 8.2m telescope is to follow up on candidate planets from transit surveys such as the TESS mission. H…

The NCORES Program: Precise planetary masses, null results, and insight into the planet mass distribution near the radius gap

David J. Armstrong, Ares Osborn, Remo Burn +39

NCORES was a large observing program on the ESO HARPS spectrograph, dedicated to measuring the masses of Neptune-like and smaller transiting planets discovered by the TESS satellit…

KOBE-1: The first planetary system from the KOBE survey. Two planets likely residing in the sub-Neptune mass regime around a late K-dwarf

O. Balsalobre-Ruza, J. Lillo-Box, A. M. Silva +35

K-dwarf stars are promising targets in the exploration of potentially habitable planets. Their properties, falling between G and M dwarfs, provide an optimal trade-off between the…

Large Interferometer For Exoplanets (LIFE). XIV. Finding terrestrial protoplanets in the galactic neighborhood

Lorenzo Cesario, Tim Lichtenberg, Eleonora Alei +62

The increased brightness temperature of young rocky protoplanets during their magma ocean epoch makes them potentially amenable to atmospheric characterization to distances from th…
