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…

Mind the Companion : Demographics of Transiting S-type Exoplanets

Lina Y. Messamah, François Bouchy, Julia Venturini +2

Exoplanet demographic studies rely on large and homogeneous catalogues, yet stellar multiplicity remains incompletely characterised in many planet samples. We update the PlanetS ca…

NGTS-39 b: A 58 d transiting warm Jupiter in an eccentric orbit

Ioannis Apergis, Daniel Bayliss, Solène Ulmer-Moll +53

We report the discovery and characterisation of NGTS-39 b (TIC 453147896 b), a warm Jupiter transiting a Sun-like star on a 58.2 day, eccentric (e = 0.386 +/- 0.019) orbit. NGTS-39…

ASTEP confirmation of a pair of long-period Jupiter-sized planets with extremely low densities transiting TOI-791

Georgina Dransfield, Antoine C. Petit, Amaury H. M. J. Triaud +45

Gas giant planets with periods orbiting Sun-like stars are a relatively uncommon outcome of planetary formation, and key questions about the nature and form…

The breaking of cold traps and onset of titanium in ultra-hot Jupiter atmospheres: WASP-189b in context

Stefan Pelletier, Romain Allart, Valentina Vaulato +56

Condensates are ubiquitous to all Solar System planets with significant (10mbar) atmospheres. The same is true for most exoplanets with characterised atmospheres, with even ultr…

The small transiting planet population revealed by ESPRESSO with extreme precision radial velocities

M. J. Hobson, B. Lavie, F. Bouchy +35

Small planets are extremely common in the Galaxy, including planets with masses and radii between those of Earth and Neptune. Characterizing these planets' masses requires ultra-pr…
