(EDP Sciences, 2017)We report the discovery of a substellar companion around the giant star HIP 67537. Based on precision radial velocity measurements from CHIRON and FEROS high-resolution spectroscopic data, we derived the following orbital ...

(EDP Sciences, 2015)Context. Precision radial velocities are required to discover and characterize exoplanets. Optical spectra that exhibit many hundreds of absorption lines can allow the m s(-1) precision levels required for this work. After ...

(BLACKWELL, 2006-02-01)We have measured the rotational velocities (v sin i) of the mass donors in a number of D'-type symbiotic stars (SSs), using the cross-correlation function method. Four out of five D' SSs with known v sin i appeared to be ...

(EDP SCIENCES S A, 2006-12)We report results from a high-resolution optical spectroscopic survey aimed to search for nearby young associations and young stars among optical counterparts of ROSAT All-Sky Survey X-ray sources in the Southern Hemisphere. ...
