The soft X-ray transient GS2000 + 25. I - an 8.3-hr modulation during outburst
Optical spectroscopy of the X-ray transient, GS2000 + 25 during its 1988 outburst shows that this system is similar to A0620 - 00 but at a greater distance (greater than 2 kpc). Photometry from La Palma and Russia is presented that reveals a 0.1-mag modulation at a period of 8.33 hr, associated with the orbital period. It is proposed that the
