Line identification of HD 34700
Listed in IVOA Registry (Virtual Observatory)
We announce the star HD 34700 to be a double-lined spectroscopic binary, and find it to be a weak-line T Tauri object.
Description
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.
