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…
