The rotational broadening and the mass of the donor star of GRS 1915+105
The rotational broadening and the mass of the donor star of GRS 1915+105
The binary parameters of the microquasar GRS 1915+105 have been determined by the detection of Doppler-shifted 12CO and 13CO lines in its K-band spectrum (Greiner et al. [CITE]). Here, we present further analysis of the same K-band VLT spectra and we derive a rotational broadening of the donor star of …
