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…

Precise mass and radius determination for two new and one known Neptune-sized planets around G Dwarf hosts

Ilaria Carleo, Grzegorz Nowak, Felipe Murgas +56

As part of the KESPRINT collaboration, we present the discovery and characterization of three exoplanets in the sub-Neptune to super-Neptune regime, spanning key regions of the exo…

Exploring the Neptunian Desert: Insights from a Homogeneous Planetary Sample

Lauren Doyle, David J. Armstrong, Lorena Acuña +26

In this paper, we present a homogeneous analysis of close-in Neptune planets. To do this, we compile a sample of TESS-observed planets using a ranking criterion which takes into ac…

Two neighbours of the ultra-short-period Earth-sized planet K2-157 b in the warm Neptunian savanna

A. Castro-González, F. Bouchy, A. C. M. Correia +30

The formation and evolution of ultra-short-period (USP) planets is poorly understood. However, it is widely thought that these planets migrated inwards through interactions with ou…

Revisiting the multi-planetary system of the nearby star HD 20794: Confirmation of a low-mass planet in the habitable zone of a nearby G-dwarf

N. Nari, X. Dumusque, N. C. Hara +44

Close-by Earth analogs and super-Earths are of primary importance because they will be preferential targets for the next generation of direct imaging instruments. Bright and close-…

TOI-6038 A b: A dense sub-Saturn in the transition regime between the Neptunian ridge and savanna

Sanjay Baliwal, Rishikesh Sharma, Abhijit Chakraborty +13

We present the discovery and characterization of a sub-Saturn exoplanet, TOI-6038~A~b, using the PARAS-2 spectrograph. The planet orbits a bright (), metal-rich late F-typ…

A sub-Earth-mass planet orbiting Barnard's star: No evidence of transits in TESS photometry

A. K. Stefanov, J. I. González Hernández, A. Suárez Mascareño +8

A sub-Earth-mass planet orbiting Barnard's star, designated as Barnard b, has been recently announced. At almost the same time, the first photometric data of Barnard's star by the…

Three super-Earths and a possible water world from TESS and ESPRESSO

M. J. Hobson, F. Bouchy, B. Lavie +51

Since 2018, the ESPRESSO spectrograph at the VLT has been hunting for planets in the Southern skies via the RV method. One of its goals is to follow up candidate planets from trans…

The compact multi-planet system GJ 9827 revisited with ESPRESSO

V. M. Passegger, A. Suárez Mascareño, R. Allart +36

GJ 9827 is a bright, nearby K7V star orbited by two super-Earths and one mini-Neptune on close-in orbits. The system was first discovered using K2 data and then further characteriz…

Two super-Earths at the edge of the habitable zone of the nearby M dwarf TOI-2095

F. Murgas, A. Castro-González, E. Pallé +41

The main scientific goal of TESS is to find planets smaller than Neptune around stars that are bright enough to allow for further characterization studies. Given our current instru…

37 New Validated Planets in Overlapping K2 Campaigns

J. P. de Leon, J. Livingston, M. Endl +24

We analysed 68 candidate planetary systems first identified during Campaigns 5 and 6 (C5 and C6) of the NASA \textit{K2} mission. We set out to validate these systems by using a su…
