Characterising TOI-732 b and c: New insights into the M-dwarf radius and density valley

A. Bonfanti, M. Brady, T. G. Wilson +88

TOI-732 is an M dwarf hosting two transiting planets that are located on the two opposite sides of the radius valley. By doubling the number of available space-based observations a…

A resonant sextuplet of sub-Neptunes transiting the bright star HD 110067

R. Luque, H. P. Osborn, A. Leleu +149

Planets with radii between that of the Earth and Neptune (hereafter referred to as sub-Neptunes) are found in close-in orbits around more than half of all Sun-like stars. Yet, thei…

A compact multi-planet system transiting HIP 29442 (TOI-469) discovered by TESS and ESPRESSO. Radial velocities lead to the detection of transits with low signal-to-noise ratio

M. Damasso, J. Rodrigues, A. Castro-González +52

We followed-up with ESPRESSO the K0V star HIP 29442 (TOI-469), already known to host a validated sub-Neptune companion TOI-469.01. We aim to verify the planetary nature of TOI-469.…

Refining the properties of the TOI-178 system with CHEOPS and TESS

L. Delrez, A. Leleu, A. Brandeker +84

The TOI-178 system consists of a nearby late K-dwarf transited by six planets in the super-Earth to mini-Neptune regime, with orbital periods between 1.9 and 20.7 days. All planets…

CHEOPS and TESS view of the ultra-short period super-Earth TOI-561 b

J. A. Patel, J. A. Egger, T. G. Wilson +75

Ultra-short period planets (USPs) are a unique class of super-Earths with an orbital period of less than a day and hence subject to intense radiation from their host star. While mo…

Company for the ultra-high density, ultra-short period sub-Earth GJ 367 b: discovery of two additional low-mass planets at 11.5 and 34 days

Elisa Goffo, Davide Gandolfi, Jo Ann Egger +38

GJ 367 is a bright (V 10.2) M1 V star that has been recently found to host a transiting ultra-short period sub-Earth on a 7.7 hr orbit. With the aim of improving the plan…

Refined parameters of the HD 22946 planetary system and the true orbital period of planet d

Z. Garai, H. P. Osborn, D. Gandolfi +85

Multi-planet systems are important sources of information regarding the evolution of planets. However, the long-period planets in these systems often escape detection. HD 22946 is…

Two Warm Neptunes transiting HIP 9618 revealed by TESS & Cheops

Hugh P. Osborn, Grzegorz Nowak, Guillaume Hébrard +126

HIP 9618 (HD 12572, TOI-1471, TIC 306263608) is a bright ( mag) solar analogue. TESS photometry revealed the star to have two candidate planets with radii of …

TOI-5678 b: A 48-day transiting Neptune-mass planet characterized with CHEOPS and HARPS

S. Ulmer-Moll, H. P. Osborn, A. Tuson +92

A large sample of long-period giant planets has been discovered thanks to long-term radial velocity surveys, but only a few dozen of these planets have a precise radius measurement…

TOI-1055 b: Neptunian planet characterised with HARPS, TESS, and CHEOPS

A. Bonfanti, D. Gandolfi, J. A. Egger +89

TOI-1055 is a Sun-like star known to host a transiting Neptune-sized planet on a 17.5-day orbit (TOI-1055 b). Radial velocity (RV) analyses carried out by two independent groups us…
