Giant Outer Transiting Exoplanet Mass (GOTEM) Survey.VII. TOI-6041: a multi-planet system including a warm Neptune exhibiting strong TTVs

N. Heidari, A. Alnajjarine, H. P. Osborn +101

We present the characterization of the TOI-6041 system, a bright () G7-type star hosting at least two planets. The inner planet, TOI-6041b, is a warm Neptune wit…

HARPS-N, TESS, and CHEOPS discover a transiting sub-Neptune and two outer companions around the bright solar analogue HD 85426

F. Lienhard, A. Mortier, A. Collier Cameron +96

We provide a detailed characterisation of the planetary system orbiting HD 85426 (TOI-1774). This bright G-type star (: 0.99 ; : 1.13 $\text{R…

Transit Timing Variations in HIP 41378: CHEOPS and TESS confirm a non-transiting sixth planet in the system

P. Leonardi, L. Borsato, L. Pagliaro +89

In multiple-planet systems, gravitational interactions of exoplanets could lead to transit timing variations (TTVs), whose amplitude becomes significantly enhanced when planets are…

Architecture of planetary systems with and without outer giant planets I. Inner planet detections around HD 23079, HD 196067, and HD 86226

J. -B. Delisle, J. P. Faria, D. Ségransan +22

Understanding the link between outer giant planets (OGPs) and inner light planets (ILPs) is key to understanding planetary system formation and architecture. The correlation betwee…

Detection and characterisation of a 106-day transiting Jupiter : TOI-2449 b / NGTS-36 b

S. Ulmer-Moll, S. Gill, R. Brahm +64

Only a handful of transiting giant exoplanets with orbital periods longer than 100 days are known. These warm exoplanets are valuable objects as their radius and mass can be measur…

A four-planet system orbiting the old thick disk star TOI-1203

D. Gandolfi, A. Alnajjarine, L. M. Serrano +120

TOI-1203 is a bright (V=8.6) G3 V star known to host a transiting warm sub-Neptune on a 25.5 d orbit. Here we report on an intensive high-precision radial velocity and photometric…
