A transiting rocky super-Earth and a non-transiting sub-Neptune orbiting the M dwarf TOI-771
G. Lacedelli, E. Pallé, Y. T. Davis +24
The origin and evolution of the sub-Neptune population is a highly debated topic in the exoplanet community. With the advent of JWST, atmospheric studies can now put unprecedented…
Titanium chemistry of WASP-121 b with ESPRESSO in 4-UT mode
B. Prinoth, J. V. Seidel, H. J. Hoeijmakers +15
Transit spectroscopy usually relies on the integration of one or several transits to achieve the S/N necessary to resolve spectral features. Consequently, high-S/N observations of…
The obliquity and atmosphere of the hot Jupiter WASP-122b (KELT-14b) with ESPRESSO: An aligned orbit and no sign of atomic or molecular absorption
M. Stangret, E. Palle, E. Esparza-Borges +21
Thanks to their short orbital periods and hot extended atmospheres, hot Jupiters are ideal candidates for atmosphere studies with high-resolution spectroscopy. New stable spectrogr…
A sub-Earth-mass planet orbiting Barnard's star
J. I. Gonzalez Hernandez, A. Suarez Mascareno, A. M. Silva +37
Barnard's star is a primary target within the ESPRESSO guaranteed time observations (GTO) as it is the second closest neighbour to our Sun after the Centauri stellar system. We…
Characterisation of TOI-406 as showcase of the THIRSTEE program: A 2-planet system straddling the M-dwarf density gap
G. Lacedelli, E. Pallè, R. Luque +31
The exoplanet sub-Neptune population currently poses a conundrum, as to whether small-size planets are volatile-rich cores without an atmosphere, or rocky cores surrounded by a H-H…
TESS and ESPRESSO discover a super-Earth and a mini-Neptune orbiting the K-dwarf TOI-238
A. Suárez Mascareño, V. M. Passegger, J. I. González Hernández +53
The number of super-Earth and mini-Neptune planet discoveries has increased significantly in the last two decades thanks to transit and radial velocity surveys. When it is possible…
CARMENES input catalog of M dwarfs: VII. New rotation periods for the survey stars and their correlations with stellar activity
Yutong Shan, Daniel Revilla, Sebastian L. Skrzypinski +40
Abridged: We measured photometric and spectroscopic for a large sample of nearby bright M dwarfs with spectral types from M0 to M9, as part of our continual effort to…
The CARMENES search for exoplanets around M dwarfs. A long-period planet around GJ 1151 measured with CARMENES and HARPS-N data
J. Blanco-Pozo, M. Perger, M. Damasso +37
Detecting a planetary companion in a short-period orbit through radio emission from the interaction with its host star is a new prospect in exoplanet science. Recently, a tantalisi…
HD22496b: the first ESPRESSO standalone planet discovery
J. Lillo-Box, J. P. Faria, A. Suárez Mascareño +32
The ESPRESSO spectrograph is a new powerful tool to detect and characterize extrasolar planets. Its design allows unprecedented radial velocity precision (down to a few tens of cm/…
Strong H emission in the young planetary mass companion 2MASS J0249-0557 c
P. Chinchilla, V. J. S. Béjar, N. Lodieu +2
Aims: Our objective is the optical and near-infrared spectroscopic characterisation of 2MASS J0249-0557 c, a recently discovered young planetary mass companion to the Pictoris…
Broadband transmission spectroscopy of HD209458b with ESPRESSO: Evidence for Na, TiO, or both
N. C. Santos, E. Cristo, O. Demangeon +42
The detection and characterization of exoplanet atmospheres is currently one of the main drivers pushing the development of new observing facilities. In this context, high-resoluti…
WASP-127b: A misaligned planet with a partly cloudy atmosphere and tenuous sodium signature seen by ESPRESSO
R. Allart, L. Pino, C. Lovis +45
The study of exoplanet atmospheres is essential to understand the formation, evolution and composition of exoplanets. The transmission spectroscopy technique is playing a significa…
HORuS transmission spectroscopy of 55 Cnc e
H. M. Tabernero, C. Allende Prieto, M. R. Zapatero Osorio +16
The High Optical Resolution Spectrograph (HORuS) is a new high-resolution echelle spectrograph available on the 10.4 m Gran Telescopio Canarias (GTC). We report on the first HORuS…
Discriminating between hazy and clear hot-Jupiter atmospheres with CARMENES
A. Sánchez-López, M. López-Puertas, I. A. G. Snellen +20
Context: Relatively large radii of some hot Jupiters observed in the ultraviolet (UV) and blue-optical are generally interpreted to be due to Rayleigh scattering by high-altitude h…
The CARMENES search for exoplanets around M dwarfs. Two planets on the opposite sides of the radius gap transiting the nearby M dwarf LTT 3780
G. Nowak, R. Luque, H. Parviainen +97
We present the discovery and characterisation of two transiting planets observed by the Transiting Exoplanet Survey Satellite (TESS) orbiting the nearby (d ~ 22 pc), bright (J ~ 9…
The CARMENES search for exoplanets around M dwarfs: Different roads to radii and masses of the target stars
Andreas Schweitzer, V. M. Passegger, C. Cifuentes +28
We determine the radii and masses of 293 nearby, bright M dwarfs of the CARMENES survey. This is the first time that such a large and homogeneous high-resolution (R>80 000) spectro…
