Two extremely irradiated volatile-rich sub-Neptunes with companions in the TOI-426 and TOI-1839 systems: Insights into arrival and survival near the lower edge of the Neptunian desert

A. Castro-González, O. Barragán, D. J. Armstrong +26

Using TESS photometry and 147 HARPS radial velocities, we confirm two extremely irradiated, volatile-rich sub-Neptunes near the lower edge of the Neptunian desert: TOI-426 b and TO…

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…

Journey of complex organic molecules: Formation and transport in protoplanetary disks

T. Benest Couzinou, O. Mousis, G. Danger +3

Complex organic molecules serve as indicators of molecular diversity. Their detection on comets, planets, and moons has prompted inquiries into their origins, particularly the cond…

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…

A low-mass sub-Neptune planet transiting the bright active star HD 73344

S. Sulis, I. J. M. Crossfield, A. Santerne +33

Context. Planets with radii of between 2-4 RE closely orbiting solar-type stars are of significant importance for studying the transition from rocky to giant planets. Aims. Our goa…

An unusually low-density super-Earth transiting the bright early-type M-dwarf GJ 1018 (TOI-244)

A. Castro-González, O. D. S. Demangeon, J. Lillo-Box +34

Small planets located at the lower mode of the bimodal radius distribution are generally assumed to be composed of iron and silicates in a proportion similar to that of the Earth.…

TOI-969: a late-K dwarf with a hot mini-Neptune in the desert and an eccentric cold Jupiter

J. Lillo-Box, D. Gandolfi, D. J. Armstrong +60

The current architecture of a given multi-planetary system is a key fingerprint of its past formation and dynamical evolution history. Long-term follow-up observations are key to c…

TOI-2196 b: Rare planet in the hot Neptune desert transiting a G-type star

Carina M. Persson, Iskra Y. Georgieva, Davide Gandolfi +52

Highly irradiated planets in the hot Neptune desert are usually either small (R < 2 Rearth) and rocky or they are gas giants with radii of >1 Rjup. Here, we report on the intermedi…

TOI-220 : a warm sub-Neptune discovered by TESS

S. Hoyer, D. Gandolfi, D. J. Armstrong +77

In this paper we report the discovery of TOI-220 , a new sub-Neptune detected by the Transiting Exoplanet Survey Satellite (TESS) and confirmed by radial velocity follow-up obse…

An Earth-sized exoplanet with a Mercury-like composition

A. Santerne, B. Brugger, D. J. Armstrong +43

The Earth, Venus, Mars, and some extrasolar terrestrial planets have a mass and radius that is consistent with a mass fraction of about 30% metallic core and 70% silicate mantle. A…
