Planetary system around LTT 1445A unveiled by ESPRESSO: Multiple planets in a triple M-dwarf system
B. Lavie, F. Bouchy, C. Lovis +32
We present radial velocity follow-up obtained with ESPRESSO of the M-type star LTT 1445A (TOI-455), for which a transiting planet b with an orbital period of~5.4 days was detected…
Detection of barium in the atmospheres of the ultra-hot gas giants WASP-76b and WASP-121b
T. Azevedo Silva, O. D. S. Demangeon, N. C. Santos +33
High-resolution spectroscopy studies of ultra-hot Jupiters have been key in our understanding of exoplanet atmospheres. Observing into the atmospheres of these giant planets allows…
Espresso observations of HE 01075240 and other CEMP-no stars with
D. Aguado, P. Molaro, E. Caffau +22
HE 01075240 is a hyper metal-poor star with . We performed high-res observations with the ESPRESSO spectrograph at the VLT to constrain the kinematical propert…
AlH lines in the blue spectrum of Proxima Centauri
Yakiv V. Pavlenko, Jonathan Tennyson, Sergei N. Yurchenko +4
The recently-computed ExoMol line lists for isotopologues of AlH are used to analyse the blue spectrum (4000-4500 Å) of Proxima Cen (M5.5 V). Comparison of the observed and compute…
Automatic model-based telluric correction for the ESPRESSO data reduction software. Model description and application to radial velocity computation
R. Allart, C. Lovis, J. Faria +21
Ground-based high-resolution spectrographs are key instruments for several astrophysical domains. Unfortunately, the observed spectra are contaminated by the Earth's atmosphere. Wh…
Transmission spectroscopy of MASCARA-1b with ESPRESSO: Challenges of overlapping orbital and Doppler tracks
N. Casasayas-Barris, F. Borsa, E. Pallé +32
Atmospheric studies at high spectral resolution have shown the presence of molecules, neutral and ionised metals, and hydrogen in the transmission spectrum of ultra-hot Jupiters, a…
Fundamental physics with ESPRESSO: Constraints on Bekenstein and dark energy models from astrophysical and local probes
C. J. A. P. Martins, S. Cristiani, G. Cupani +21
Dynamical scalar fields in an effective four-dimensional field theory are naturally expected to couple to the rest of the theory's degrees of freedom, unless some new symmetry is p…
A novel framework for semi-Bayesian radial velocities through template matching
A. M. Silva, J. P. Faria, N. C. Santos +28
The detection and characterization of an increasing variety of exoplanets has been in part possible thanks to the continuous development of high-resolution, stable spectrographs, a…
A quarter century of spectroscopic monitoring of the nearby M dwarf Gl 514. A super-Earth on an eccentric orbit moving in and out of the habitable zone
M. Damasso, M. Perger, J. M. Almenara +31
We investigated the presence of planetary companions around the nearby (7.6 pc) and bright ( mag) early-type M dwarf Gl 514, analysing 540 radial velocities collected over nea…
Fundamental Physics with ESPRESSO, Constraining a simple parametrisation for varying
Vitor da Fonseca, Tiago Barreiro, Nelson J. Nunes +24
The spectrograph ESPRESSO recently obtained a limit on the variation of the fine-structure constant, , through measurements along the line of sight of a bright quasar with a pre…
HADES RV Programme with HARPS-N at TNG XV. Planetary occurrence rates around early-M dwarfs
M. Pinamonti, A. Sozzetti, J. Maldonado +28
We present the complete Bayesian statistical analysis of the HArps-n red Dwarf Exoplanet Survey (HADES), which monitored the radial velocities of a large sample of M dwarfs with HA…
A candidate short-period sub-Earth orbiting Proxima Centauri
J. P. Faria, A. Suárez Mascareño, P. Figueira +34
Proxima Centauri is the closest star to the Sun. This small, low-mass, mid M dwarf is known to host an Earth-mass exoplanet with an orbital period of 11.2 days within the habitable…
CaRM: Exploring the chromatic Rossiter-McLaughlin effect. The cases of HD 189733b and WASP-127b
E. Cristo, N. C. Santos, O. Demangeon +34
In this paper we introduce CaRM, a semi-automatic code for the retrieval of broadband transmission spectra of transiting planets through the chromatic Rossiter-McLaughlin method. W…
