A resonant sextuplet of sub-Neptunes transiting the bright star HD 110067
R. Luque, H. P. Osborn, A. Leleu +149
Planets with radii between that of the Earth and Neptune (hereafter referred to as sub-Neptunes) are found in close-in orbits around more than half of all Sun-like stars. Yet, thei…
Ground-breaking Exoplanet Science with the ANDES spectrograph at the ELT
Enric Palle, Katia Biazzo, Emeline Bolmont +56
In the past decade the study of exoplanet atmospheres at high-spectral resolution, via transmission/emission spectroscopy and cross-correlation techniques for atomic/molecular mapp…
Confirmation of TiO absorption and tentative detection of MgH and CrH in the atmosphere of HAT-P-41b
C. Jiang, G. Chen, F. Murgas +3
Understanding the role of optical absorbers is critical for linking the properties of the day-side and terminator atmospheres of hot Jupiters. This study aims to identify the signa…
The GAPS Programme at TNG L -- TOI-4515 b: An eccentric warm Jupiter orbiting a 1.2 Gyr-old G-star
I. Carleo, L. Malavolta, S. Desidera +68
Context. Different theories have been developed to explain the origins and properties of close-in giant planets, but none of them alone can explain all of the properties of the war…
Spright: a probabilistic mass-density-radius relation for small planets
Hannu Parviainen, Rafael Luque, Enric Palle
We present Spright, a Python package that implements a fast and lightweight mass-density-radius relation for small planets. The relation represents the joint planetary radius and b…
TOI-1801 b: A temperate mini-Neptune around a young M0.5 dwarf
M. Mallorquín, E. Goffo, E. Pallé +79
We report the discovery, mass, and radius determination of TOI-1801 b, a temperate mini-Neptune around a young M dwarf. TOI-1801 b was observed in TESS sectors 22 and 49, and the a…
Transit Timing Variations in the three-planet system: TOI-270
Laurel Kaye, Shreyas Vissapragada, Maximilian N. Gunther +69
We present ground and space-based photometric observations of TOI-270 (L231-32), a system of three transiting planets consisting of one super-Earth and two sub-Neptunes discovered…
Confirmation of an He I evaporating atmosphere around the 650-Myr-old sub-Neptune HD235088 b (TOI-1430 b) with CARMENES
J. Orell-Miquel, M. Lampón, M. López-Puertas +31
HD235088 (TOI-1430) is a young star known to host a sub-Neptune-sized planet candidate. We validated the planetary nature of HD235088 b with multiband photometry, refined its plane…
TOI 4201 b and TOI 5344 b: Discovery of Two Transiting Giant Planets Around M Dwarf Stars and Revised Parameters for Three Others
J. D. Hartman, G. Á. Bakos, Z. Csubry +62
We present the discovery from the TESS mission of two giant planets transiting M dwarf stars: TOI 4201 b and TOI 5344 b. We also provide precise radial velocity measurements and up…
Featureless transmission spectra of 12 giant exoplanets observed by GTC/OSIRIS
C. Jiang, G. Chen, E. Pallé +3
Exoplanet atmospheres are the key to understanding the nature of exoplanets. To this end, transit spectrophotometry provides us opportunities to investigate the physical properties…
TOI-1416: A system with a super-Earth planet with a 1.07d period
H. J. Deeg, I. Y. Georgieva, G. Nowak +49
TOI 1416 (BD+42 2504, HIP 70705) is a V=10 late G or early K-type dwarf star with transits detected by TESS. Radial velocities verify the presence of the transiting planet TOI-1416…
Discovery of a substellar companion in the TESS light curve of the Scuti/ Doradus hybrid pulsator HD 31221
Sz. Kálmán, A. Derekas, Sz. Csizmadia +9
Close-in, sub-stellar companions to Scuti type stars present a highly suitable testbed for examining how planetary-mass objects can influence stellar pulsations. We aim to cons…
The mass determination of TOI-519 b: a close-in giant planet transiting a metal-rich mid-M dwarf
Taiki Kagetani, Norio Narita, Tadahiro Kimura +33
We report the mass determination of TOI-519 b, a transiting substellar object around a mid-M dwarf. We carried out radial velocity measurements using Subaru / InfraRed Doppler (IRD…
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…
Temporal albedo variability in the phase curve of KELT-1b
Hannu Parviainen
The dayside brightness spectrum of a highly irradiated transiting brown dwarf KELT-1b has been shown to be challenging to explain with the current brown dwarf atmosphere models. Th…
