The Longest-period Young Transiting Exoplanets. A Duo of Puffy Giants inside a Debris Disk

Carlos del Burgo, Alejandro Suárez Mascareño, Ana Heras Pastor +35

We identify two large-radius planets around the F-type star HD 114082 as the longest-period young transiting exoplanets known. From the first transit, detected by NASA's Transiting…

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…

TOI-3288 b and TOI-4666 b: two gas giants transiting low-mass stars characterised by NIRPS

Yolanda G. C. Frensch, François Bouchy, Gaspare Lo Curto +62

Gas giant planets orbiting low-mass stars are uncommon outcomes of planet formation. Increasing the sample of well-characterised giants around early M dwarfs will enable population…

Possible Evidence for the Presence of Volatiles on the Warm Super-Earth TOI-270 b

Louis-Philippe Coulombe, Björn Benneke, Joshua Krissansen-Totton +25

The search for atmospheres on rocky exoplanets is a crucial step in understanding the processes driving atmosphere formation, retention, and loss. Past studies have revealed the ex…

A systematic bias in template-based RV extraction algorithms

André M. Silva, N. C. Santos, J. P. Faria +30

In this paper we identify and explore a previously unidentified, multi meter-per-second, systematic correlation between time and RVs inferred through TM and LBL methods. We evaluat…

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…

ESPRESSO reveals blueshifted neutral iron emission lines on the dayside of WASP-76 b

A. R. Costa Silva, O. D. S. Demangeon, N. C. Santos +34

Ultra hot Jupiters (gas giants, Teq>2000 K) are intriguing exoplanets due to their extreme atmospheres. Their torrid daysides can be characterised using ground-based high-resolutio…

New Mass and Radius Constraints on the LHS 1140 Planets -- LHS 1140 b is Either a Temperate Mini-Neptune or a Water World

Charles Cadieux, Mykhaylo Plotnykov, René Doyon +43

The two-planet transiting system LHS 1140 has been extensively observed since its discovery in 2017, notably with , HST, TESS, and ESPRESSO, placing strong constraints on…

Nightside condensation of iron in an ultra-hot giant exoplanet

David Ehrenreich, Christophe Lovis, Romain Allart +94

Ultra-hot giant exoplanets receive thousands of times Earth's insolation. Their high-temperature atmospheres (>2,000 K) are ideal laboratories for studying extreme planetary climat…

The transiting multi-planet system HD3167: a 5.7 MEarth Super-Earth and a 8.3 MEarth mini-Neptune

Davide Gandolfi, Oscar Barragán, Artie P. Hatzes +42

HD3167 is a bright (V=8.9 mag) K0V star observed by the NASA's K2 space mission during its Campaign 8. It has been recently found to host two small transiting planets, namely, HD31…
