Upside down: GJ3090 b the first retrograde exoplanet around an M dwarf detected with NIRPS

Y. Carteret, V. Bourrier, L. Parc +57

The angle between stellar spin axis and planetary orbital plane can provide key insights into the formation and dynamical evolution of planetary systems. In particular, this measur…

TOI-1080 b: a temperate, rocky planet orbiting a quiet M4V host

Y. Gómez Maqueo Chew, G. Dransfield, K. Barkaoui +41

We present the detection and validation of a small, temperate transiting exoplanet orbiting TOI-1080 every 3.9652482 days. The host is a quiet M4V star…

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…

Hydride ion continuum hides absorption signatures in the NIRPS near-infrared transmission spectrum of the ultra-hot gas giant WASP-189b

Valentina Vaulato, Stefan Pelletier, David Ehrenreich +77

Ultra-hot Jupiters showcase extreme atmospheric conditions, including molecular dissociation, ionisation, and significant day-to-night temperature contrasts. Their close proximity…

Search for giant planets in M67 V: a warm Jupiter orbiting the turn-off star S1429

Luis Thomas, Roberto Saglia, Luca Pasquini +9

Planets orbiting members of open or globular clusters offer a great opportunity to study exoplanet populations systematically as stars within clusters provide a mostly homogeneous…

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…

On the behaviour of spin-orbit connection of exoplanets

Bruno L. Canto Martins, Yuri S. Messias, Maria I. Arruda Gonçalves +5

Star-planet interactions play, among other things, a crucial role in planetary orbital configurations by circularizing orbits, aligning the star and planet spin and synchronizing s…

A dearth of close-in planets around rapidly rotating stars or a dearth of data?

Y. S. Messias, L. L. A. de Oliveira, R. L. Gomes +4

A dearth of close-in planets orbiting rapid rotators was reported almost a decade ago. According to this view only slowly spinning stars with rotation periods longer than 5-10 days…

TOI-269 b: An eccentric sub-Neptune transiting a M2 dwarf revisited with ExTrA

M. Cointepas, J. M. Almenara, X. Bonfils +59

We present the confirmation of a new sub-Neptune close to the transition between super-Earths and sub-Neptunes transiting the M2 dwarf TOI- 269 (TIC 220479565, V = 14.4 mag, J = 10…

A pair of TESS planets spanning the radius valley around the nearby mid-M dwarf LTT 3780

Ryan Cloutier, Jason D. Eastman, Joseph E. Rodriguez +84

We present the confirmation of two new planets transiting the nearby mid-M dwarf LTT 3780 (TIC 36724087, TOI-732, , , =0.374 R, =0.401 M$_{\…
