内容記述 | We present the results of optical spectroscopic observations of the mass donor star in SS 433 with Subaru and Gemini. Subaru/FOCAS observations were performed on 4 nights of 2007 October, covering the orbital phase of phi nearly equal to 0. We calculate cross correlation function of these spectra with that of the reference star HD 9233 in spectral regions that are selected to avoid "strong" absorption lines accompanied with contaminating emission components. The same analysis is applied to the archive data of Gemini/GMOS by Hillwig and Gies (2008). From the Subaru and Gemini CCF results, the amplitude of radial velocity curve of the donor star is determined to be 56.7 +/- 3.7 km s(sup -1) with a systemic velocity of 61.3 +/- 2.5 km s(sup -1). Combining with the radial velocity of the compact object, we derive the mass of the donor star and compact object to be M(sub O) = 12.2(sup +2.3)(sub -2.1) solar mass and M(sub X) = 4.1(sup +0.8)(sub -0.7) solar mass, respectively. However, these values should be taken as upper limits if we consider the heating effects (Kubota et al. 2009). We conclude that the compact star in SS 433 is most likely a low mass black hole, although the possibility of a massive neutron star cannot be firmly ruled out. | |||||
