Abstract
All available photometric and spectroscopic observations were collected and used as the basis of a detailed analysis of the close binary IM Mon. The orbital period of the binary was refined to 1.19024249(14) d. IM Mon is classified to be a detached binary system in contrast to the contact configuration estimations in the literature. The absolute parameters of IM Mon were derived by the simultaneous solutions of light and radial velocity curves. ZAMS stars for the primary and secondary components respectively. The modelling of the high resolution spectra revealed the rotational velocities of the component stars. The photometric distance of 353(59) pc was found more precise and reliable than Hipparcos distance of 341(85) pc. The evolutionary age of 11.5(1.5) Myr was obtained for IM Mon. Kinematical and dynamical analysis support the membership of the young thin-disk population system IM Mon to the Ori OB1a association dynamically. Using the membership of IM Mon to Ori OB1a, we reached to the distance, age and metallicity information of Ori OB1a sub-group.
