Descripción
This work is part of the project CARMENES (Calar Alto search for high-Resolution M dwarfs With Exoearths With Near-infrared and optical Echelle spectrographs) searching for Earthlike exoplanets in M dwarf stars (Quirrenbach et al. 2014SPIE.9147E..1FQ). Our goal is to characterize the rotation periods of the M-type dwarf stars of CARMENES input catalog in order to distinguish variations in radial velocity produced by magnetic activity of those produced by possible exoplanets. These data will also allow us to study in detail the dependence of chromospheric activity with rotation in this type of stars. We are analyzing photometric series of our input stars obtained by surveys as MEarth, ASAS or K2 and doing our own observations at various telescopes in collaboration with amateur observatories. We are also developing and testing new photometric techniques based on intelligent modeling of atmospheric turbulence to improve rotation curves

    Study of basaltic asteroids through their phase curves
    Introduction Classified as type-V, the basaltic asteroids of the Main Belt (MB), for the most part, are connected to Vesta's dynamic family. However, since the discovery of the V-type asteroid (1459) Magnya in the outer MB, several new asteroids have been found in different regions, including V-types from inner regions not belonging to the Vesta
