J/A+A/408/L29       Line identification of HD 34700      (Arellano Ferro+, 2003)

The new T Tauri double-lined spectroscopic binary HD 34700. Arellano Ferro A., Giridhar S. <Astron. Astrophys. 408, L29 (2003)> =2003A&A...408L..29A
ADC_Keywords: Binaries, spectroscopic ; Radial velocities ; Spectroscopy Keywords: Spectroscopic binaries - T Tauri stars Abstract: We 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 6708Å. 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. Description: Identified double lines in the spectrum of HD 34700. Only lines radial velocities of both the blue and the red components are listed. Only those lines which have both the components clearly identified and unaffected by the neighbouring lines are included. The table also contains the lower excitation potentials and the ratios of line strengths of the two components, which are consistently of similar strengths.
