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…
Catalog for the ESPRESSO blind radial velocity exoplanet survey
S. Hojjatpanah, P. Figueira, N. C. Santos +19
One of the main scientific drivers for ESPRESSO,Échelle SPectrograph, is the detection and characterization of Earth-class exoplanets. With this goal in mind, the ESPRESSO Guarante…
On the iron ionization balance of cool stars
M. Tsantaki, N. C. Santos, S. G. Sousa +3
High-resolution spectroscopic studies of solar-type stars have revealed higher iron abundances derived from singly ionized species compared to neutral, violating the ionization equ…
