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.

    Spectral library of age-benchmark low-mass stars and brown dwmarfs
    In recent years, some extremely red brown dwarfs have been discovered. They were believed to have a low surface gravity, but many of their spectral...

    Spectral properties of asteroids in cometary orbits
    Aims: In this paper we analyze the spectra of a sample of asteroids in cometary orbits (ACOs) in order to understand the relationship between them, the Jupiter...

    Spectral properties of near-Earth objects with low-Jovian Tisserand invariant
    The near-Earth objects with low-Jovian Tisserand invariant (T J) represent about 9 per cent of the known objects orbiting in the near-Earth space, being subject...

    Spectral Rotational Characterization of the Didymos System prior to the DART Impact
    The smallest member of the Didymos binary near-Earth object system (Dimorphos) is the target of the DART/LICIACube mission, the first attempt to change the...

    Spectrally blue hydrated parent body of asteroid (162173) Ryugu
    Ryugu is a carbonaceous rubble-pile asteroid visited by the Hayabusa2 spacecraft. Small rubble pile asteroids record the thermal evolution of their much larger...

    Spectroscopic and dynamical properties of comet C/2018 F4, likely a true average former member of the Oort cloud
    Context. The population of comets hosted by the Oort cloud is heterogeneous. Most studies in this area have focused on highly active objects, those with small...

    Spectroscopic follow-up of L- and T-type proper-motion member candidates in the Pleiades
    We report on the near-infrared (JHK-bands) low-resolution spectroscopy and red optical (Z-band) photometry of seven proper-motion, very low-mass substellar...
