dc.description.abstract | New optical spectroscopy of the HMXB microquasar LSI +61 303 is presented. Eccentric orbital fits to our radial velocity measurements yield updated orbital parameters in good agreement with previous work. Our orbital solution indicates that the periastron passage occurs at radio phase 0.23 and the X-ray/radio outbursts are triggered 2.5--4 days after the compact star passage. The spectrum of the optical star is consistent with a B0 V spectral type and contributes ~65 percent of the total light, the remaining due to emission by a circumstellar disc. We also measure the projected rotational velocity to be v sin i = 113 km/s. | - |
