| Abstract: | From 44 spectra obtained at Asiagno in 1969–1971, we infer the orbital elements of the double lines system LY Aur. The mass-functions indicate rather massive components, with mass ratio 0.58±0.03. This is in good agreement with a contact photometric solution found by Eaton (1978). Combination of spectroscopic and photometric data yields the following absolute elements:m
1=13,m
2=22, separation 34.5,R
1=11,R
2=15, in solar units.A short comment on the large number of massive contact systems is given. |
