Scientific paper

We present new spectroscopic orbit for ρ Aurigae. Velocity observations secured over two years, in combination with archival data, have produced sufficiently good phase coverage to yield a well-defined orbit. Using 92 measurements of radial velocity the following orbital elements have been found: P=34.49321+/-0.00057days, K=39.8+/-0.8km/s, e=0.104+/-0.019, ω=3.4+/-12.0deg, T_maxRV_=47962.5+/-2.0 J.D., leading to f(m)=0.220Msun_ .
