We present the results of an Hα monitoring campaign on the BeXRB and microquasar system LS I +61 303. We use radial velocity measurements of He I lines in our spectra to re-evaluate the orbital elements and to better establish the time of periastron. We list equivalent widths and other parameters for the Hα emission line and discuss the orbital phase(More)
We present results from new optical and UV spectroscopy of the unusual binary system SS 433, and we discuss the relationship of the particular spectral components we observe to the properties of the binary. These spectral components include: (1) The continuum spectrum which we associate with flux from the super-Eddington accretion disk and the dense part of(More)
