ADC_Keywords: Stars, variable ; Radial velocities Keywords: instrumentation: spectrographs - methods: observational - techniques: radial velocities - planetary systems - stars: individual: BD+20 1790 - stars: activity Abstract: The young active star BD +20 1790 has been inferred to host a substellar companion from radial-velocity measurements that detected the reflex motion induced on the parent star. We attempt to completely characterize the radial-velocity signal in order to assess its nature. Description: We used the CORALIE spectrograph to obtain precise (∼10m/s) radial-velocity measurements of this active star, while characterizing the bisector span variations. We took particular care to correctly sample both the proposed planetary orbital period, of 7.8 days, and the stellar rotation period, of 2.4 days. ************************************************************************** * * * Sorry, but the author(s) never supplied the tabular material * * (radial velocity data) as announced in the paper. * * The image of the radial velocity curve only is available here. * * * ************************************************************************** Objects: ---------------------------------------------------- RA (2000) DE Designation(s) ---------------------------------------------------- 07 23 43.6 +20 24 59 BD+20 1790 = TYC 1355-214-1 ---------------------------------------------------- File Summary:

Note on img7.png: CORALIE RV measurements for BD+20 1270. The measured RVs are plotted as a function of time (top pannel) and phase-folded on the orbit announced by Hernan-Obispo et al. (2010, Cat. J/A+A/512/A45), (bottom panel). The published RV measurements and error bars are presented as well (square symbols).
