CHEOPS photometry from 2024 reveals a reversal in the transit-timing variations of AU Mic c
Z. Garai, Gy. M. Szabó, D. Gandolfi +90
We present new CHEOPS transit observations of AU Mic b and AU Mic c obtained between June and September 2024, extending the baseline of transit-timing measurements of this young pl…
HD 148797: A bright F-type star with two moderate-period low-density sub-Jovian planets. Compact multi-planet architectures are common in the Neptunian savanna
J. M. Almenara, A. Castro-González, R. Mardling +26
We report the confirmation and characterisation of two moderate-period sub-Jovian planets transiting the bright F-type star HD 148797 (G=9.4 mag, Teff=6441 +/- 51 K). Using photome…
CORALIE radial-velocity search for companions around evolved stars (CASCADES) V. Three planetary companions and achievable precision
P. Figueira, E. Fontanet, J. P. Faria +9
Aims. We expand the planetary census around massive stellar hosts through a long-term campaign of high-precision radial velocity (RV) measurements on evolved stars. Methods. We ana…
Two inner dust clumps in PDS 70. A third protoplanet traced by trojan material or a substructured inner disk?
O. Balsalobre-Ruza, V. Christiaens, N. Huélamo +21
The PDS 70 cavity hosts two confirmed directly imaged protoplanets and a third inner planet candidate at 13au, labeled PDS 70 d. Despite its Keplerian motion, its unusually blue sp…
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 multi-planet system TOI-5624: Four transiting sub-Neptunes with an outer companion revealed by transit-timing variations
A. Bonfanti, D. Gandolfi, P. Leonardi +96
Following the 2022 alert of a TESS object of interest transiting TOI-5624 (a G7 V star 100 pc away), a CHEOPS campaign in 2023 detected four planetary signals at $P_b\approx3…
