Abstract

EM Boo is a relatively bright (V = 8.98 mag.) and short orbital period (P⁓2.45 days) binary star member of the

multiple system WDS J14485+2445AB. There is neither photometric nor spectroscopic study of the system in the

literature. In this work, we obtained spectroscopic orbital parameters of the system from new high resolution

spectroscopic observations made with échelle spectrograph attached to UBT60 telescope of Akdeniz University. The

spectroscopic solution yielded the values K1 = 100.7±2.6 km/s, K2 = 120.1±2.6 km/s and Vγ = -14.6±3.1 km/s, and thus

the mass ratio of the system q = 0.838±0.064.
