Inferring planet occurrence rates from radial velocities
J. P. Faria, J. -B. Delisle, D. Ségransan
We introduce a new method to infer the posterior distribution for planet occurrence rates from radial-velocity (RV) observations. The approach combines posterior samples from the a…
PoET: the Paranal solar ESPRESSO Telescope
Nuno C. Santos, Alexandre Cabral, Inês Leite +42
The detection and characterisation of other "Earths", orbiting other suns, is a bold objective of present-day astrophysics. However, this quest is severely challenged by astrophysi…
ANDES, the high resolution spectrograph for the ELT: science goals, project overview and future developments
A. Marconi, M. Abreu, V. Adibekyan +286
The first generation of ELT instruments includes an optical-infrared high-resolution spectrograph, indicated as ELT-HIRES and recently christened ANDES (ArmazoNes high Dispersion E…
Probing the small scale structure of the Inter-Galactic Medium with ESPRESSO: spectroscopy of the lensed QSO UM673
Stefano Cristiani, Guido Cupani, Andrea Trost +20
The gravitationally lensed quasar J014516.6-094517 at z=2.719 has been observed with the ESPRESSO instrument at the ESO VLT to obtain high-fidelity spectra of the two images A and…
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…
Planetary system LHS 1140 revisited with ESPRESSO and TESS
J. Lillo-Box, P. Figueira, A. Leleu +17
LHS 1140 is an M dwarf known to host two known transiting planets at orbital periods of 3.77 and 24.7 days. The external planet (LHS 1140 b) is a rocky super-Earth that is located…
Benchmark stars, benchmark spectrographs: Detailed spectroscopic comparison of ESPRESSO, PEPSI, and HARPS data for Gaia benchmark stars
V. Adibekyan, S. G. Sousa, N. C. Santos +14
Gaia benchmark stars are selected to be calibration stars for different spectroscopic surveys. Very high-quality and homogeneous spectroscopic data for these stars are therefore re…
Beyond the exoplanet mass-radius relation
S. Ulmer-Moll, N. C. Santos, P. Figueira +2
Mass and radius are two fundamental properties for characterising exoplanets, but only for a relatively small fraction of exoplanets are they both available. Mass is often derived…
Understanding stellar activity-induced radial velocity jitter using simultaneous K2 photometry and HARPS RV measurements
M. Oshagh, N. C. Santos, P. Figueira +15
One of the best ways to improve our understanding of the stellar activity-induced signal in radial velocity (RV) measurements is through simultaneous high-precision photometric and…
BGLS: A Bayesian formalism for the generalised Lomb-Scargle periodogram
A. Mortier, J. P. Faria, C. M. Correia +2
Context. Frequency analyses are very important in astronomy today, not least in the ever-growing field of exoplanets, where short-period signals in stellar radial velocity data are…
