cds-question@unistra.frspectroscopic-binary-starsradial-velocityspectroscopyWe announce the star HD 34700 to be a double-lined spectroscopic binary, and find it to be a weak-line T Tauri object. The spectra of both components are very similar and both show the Li I feature at 6708{AA}. Strong arguments in favour of the binary nature of the star as opposed to other possibilities are offered. It is very likely that the companion is also a T Tauri star of similar mass. We present, in Table 2, a list of the lines identified and the radial velocities of the two components for three epochs.2003A&A...408L..29Ahttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/408/L29CatalogResearchIsServedByTAP VizieR generic servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/408/L29https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/408/L29http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/408/L29https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/408/L29https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/408/L29http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/408/L29GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticaldefaultJ/A+A/408/L29/table2Identified double lines in the spectrum of HD 34700recnoRecord number assigned by the VizieR team.
