Stellar Activity and Radial Velocities in M Dwarfs
(2024-07-17)Stellar activity is one of the principal obstacles to achieving sub 1 m/s radial velocity precision in exoplanet detection surveys. Understanding how stellar activity affects the stellar environment is crucial to mitigating ... -
Radial velocities in low mass stars: improving the wavelength solution of astronomical spectrographs and understanding stellar noise
(2017-11-10)The radial velocity method has been used to discover hundreds of extrasolar planets in the past two decades. The continuous improvements in radial velocity precision have revealed several rocky planets in the habitable ... -
Characterisation of star-planet systems
(2017-07-05)After the first confirmed detection of an exoplanet in 1995, their number has significantly increased to 3 557 confirmed planets around other stars (www.exoplanet.eu, Dec. 2016). The most successful techniques for planet ... -
Transmission spectra of highly irradiated extrasolar planet atmospheres
(2016-11-11)The ground-based facilities ESO/VLT+FORS2 (Very Large Telescope + FOcal Reducer and low dispersion Spectrograph) and GTC+OSIRIS (Gran Telescopio CANARIAS + Optical System for Imaging and low Resolution Integrated Spectroscopy) ... -
High-resolution spectroscopy of low-mass stars
(2015-03-23)High-resolution spectroscopy is employed to investigate a large sample of open cluster low-mass stars. The stellar rotation and magnetic activity of these stars are measured and their correlation is studied. I find in ...
