La estrella peculiar 17 Leporis
Red spectra taken at Mount Wilson and at Lick confirm Widing's conclusion that 17 Leporis is a binary system and that the secondary component is a late type star. Widing's tentative period has been improved to 258.2 days, and values of K₂= 22.5 km/sec and f(M₂) =0.30 Mₒ have been derived....

| description |
Red spectra taken at Mount Wilson and at Lick confirm Widing's conclusion that 17 Leporis is a binary system and that the secondary component is a late type star. Widing's tentative period has been improved to 258.2 days, and values of K₂= 22.5 km/sec and f(M₂) =0.30 Mₒ have been derived. The primary star's velocity curve will have to be derived from the Mg II λ 4481 line but the presently available material in the photographic region is not sufficient for the purpose. Struve's earliest Yerkes radial velocities from Mg II λ 4481 seem to confirm the period but nothing is suggested in regard to the value of K₁. |
