We find the star HD 34700 to be a double-lined spectroscopic binary.
We also identify it as a weak-line T Tauri object.
The spectra of both components are very similar and both show the Li I
feature at 6708 Å. 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.
A projected rotational velocity, , of 25 and 23 km s-1 has been estimated for the blue and red components.
We present a list of the lines identified and the radial velocities of the two
components on three spectra obtained on consecutive nights.
Key words: spectroscopic binaries / T Tauri stars
