Nowadays, low mass stars, and in particular M dwarf stars, are key targets towards achieving this goal. In this thesis, I focus on the study of the short-time domain of M dwarf stars with the aim of searching for short period planets, but also for the first detection of stellar pulsations on this spectral type. Both science goals are the primary objectives of the “Cool Tiny Beats” (CTB) survey, which has produced most of the data used in this thesis. CTB data consist in high-resolution and high-cadence spectroscopic Doppler measurements taken either with HARPS or HARPS-N spectrographs. 2017-02-15T08:47:38Z 2017-02-15T08:47:38Z 2016 2016-11-25 info:eu-repo/semantics/doctoralThesis Modroño Berdiñas, Z.
