Exoplanetary Systems & Solar System (SEYSS)
The area of planetary and solar systems involves several research groups working on Exoplanets, Solar System and Cultural Astronomy.Our main objectives are:
The detection and characterization of giant and rocky planets around nearby stars using the most advanced instruments (CARMENES, ESPRESSO, HARPS Norte y Sur, SONG, LCO, MUSCAT2) and space missions (CoRoT, Kepler K2, CHEOPS, TESS and PLATO). The group is particularly interested in the study of terrestrial planets in the habitable zone of their host stars where water can be in liquid form.
The characterization of the atmospheres of planets to know their structure and composition, both by transits and direct imaging, using ground-based telescopes such as GTC and space missions such as CHEOPS.
Investigate the formation of exoplanet systems by studying the chemical composition of planet host stars, and the dynamical evolution of exoplanets at their early stages of formation.
Study the physical properties of different families of minor bodies of the Solar System (asteroids, comets, trans-neptunian objects, etc.) to understand the origin and evolution of Solar System with GTC and space missions such as OSIRIS-REx.
The study of ancient cosmologies through cultural astronomy and the defense of cultural heritage through the astronomy.
Thermophysical properties of near-Earth asteroid (341843) 2008 EV5 from WISE data
Aims: We derive the thermal inertia of 2008 EV5, the baseline target for the Marco Polo-R mission proposal, and infer information about the size of the...
Three Long-period Transiting Giant Planets from TESS
We report the discovery and orbital characterization of three new transiting warm giant planets. These systems were initially identified as presenting single...
Three planets transiting the evolved star EPIC 249893012: a hot 8.8-M<SUB>⊕</SUB> super-Earth and two warm 14.7 and 10.2-M<SUB>⊕</SUB> sub-Neptunes
We report the discovery of a new planetary system with three transiting planets, one super-Earth and two sub-Neptunes, that orbit EPIC 249893012, a G8 IV-V...
We present three giant stars from the ongoing Penn State–Toruń Planet Search with the Hobby–Eberly Telescope, which exhibit radial velocity (RV) variations that...
Three Red Suns in the Sky: A Transiting, Terrestrial Planet in a Triple M-dwarf System at 6.9 pc
We present the discovery from Transiting Exoplanet Survey Satellite (TESS) data of LTT 1445Ab. At a distance of 6.9 pc, it is the second nearest transiting...
Three short-period Jupiters from TESS. HIP 65Ab, TOI-157b, and TOI-169b
We report the confirmation and mass determination of three hot Jupiters discovered by the Transiting Exoplanet Survey Satellite (TESS) mission: HIP 65Ab (TOI...
We present the discovery of three small planets transiting K2-136 (LP 358 348, EPIC 247589423), a late K dwarf in the Hyades. The planets have orbital periods...
