Understanding eccentric temperate giants: an in-depth study of the architecture and stellar obliquity of the TOI-2134 system

Federica Rescigno, Manu Stalport, Ancy Anna John +28

We revisit the TOI-2134 planetary system with three new high-cadence TESS sectors and 98 more spectra. This new analysis confirms the two orbiting planets by simultaneously modelli…

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. Zieliński +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…

A decade of monitoring the HIP 41378's planetary system

S. Grouffal, A. Santerne, X. Dumusque +32

Multi-planetary systems provide key constraints on planet formation and evolution, as their architecture encodes the dynamical history of planets formed within a common protoplanet…

The RoPES project with HARPS and HARPS-N III. Two candidate planets orbiting the G-type star HD 161098

N. Nari, A. Suárez Mascareño, J. I. González Hernández +9

Context. The development of refined instruments and techniques for a detailed analysis of the radial velocities (RVs) of stars other than the Sun allows the presence of planetary s…

Modelling solar radial velocities and photometric variability with SOAPv4

Alba Barka, Eduardo Cristo, Ângela R. G. Santos +5

Stellar activity remains one of the main limitations in the detection of Earth-like planets using radial velocity (RV) measurements. The Sun, as the only star for which surface fea…

The RoPES project with HARPS and HARPS-N II. A third planet in the multi-planet system HD 176986

N. Nari, A. Suárez Mascareño, J. I. González Hernández +7

Earth-like planets orbiting in the habitable zone of K- to G-type stars create an RV effect in amplitude of less than 1 \si{\meter\per\second} and have orbital periods of hundreds…
