A hot mini-Neptune and a temperate, highly eccentric sub-Saturn around the bright K-dwarf TOI-2134
F. Rescigno, G. Hébrard, A. Vanderburg +64
We present the characterisation of an inner mini-Neptune in a 9.22920050.0000063 day orbit and an outer mono-transiting sub-Saturn planet in a 95.50 day orbi…
TOI-4860 b, a short-period giant planet transiting an M3.5 dwarf
J. M. Almenara, X. Bonfils, E. M. Bryant +47
We report the discovery and characterisation of a giant transiting planet orbiting a nearby M3.5V dwarf (d = 80.4 pc, = 15.1 mag, =11.2 mag, R = 0.358 0.015 R$…
Homogeneous search for helium in the atmosphere of 11 gas giant exoplanets with SPIRou
R. Allart, P. -B. Lemée-Joliecoeur, A. Y. Jaziri +31
The metastable helium triplet in the near-infrared (10833Å) is among the most important probes of exoplanet atmospheres. It can trace their extended outer layers and constrain mass…
Two Warm Neptunes transiting HIP 9618 revealed by TESS & Cheops
Hugh P. Osborn, Grzegorz Nowak, Guillaume Hébrard +126
HIP 9618 (HD 12572, TOI-1471, TIC 306263608) is a bright ( mag) solar analogue. TESS photometry revealed the star to have two candidate planets with radii of …
: a data-driven approach to correct for systematics in RV data -- Application to SPIRou data of the planet-hosting M dwarf GJ 251
M. Ould-Elhkim, C. Moutou, J-F. Donati +18
Context: Recent advances in the development of precise radial velocity (RV) instruments in the near-infrared (nIR) domain, such as SPIRou, have facilitated the study of M-type star…
The SOPHIE search for northern extrasolar planets. XIV. A temperate ( K) super-earth around the nearby star Gliese 411
R. F. Díaz, X. Delfosse, M. J. Hobson +33
Periodic radial velocity variations in the nearby M-dwarf star Gl411 are reported, based on measurements with the SOPHIE spectrograph. Current data do not allow us to distinguish b…
