Description
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
