Copernicus - X-ray observations of 3U 9759-49.
Abstract
Possible associations between the weak X-ray source 3U 0750-49 and bright variable stars are investigated using X-ray data from the Copernicus satellite on V Pup and HD 64740, two bright variable stars within the Uhuru error box for 3U 0750-49. Analysis of the data indicates that the X-ray source is almost certainly closer to V Pup than to HD 64740, and the latter object is completely ruled out as a possible candidate. An error box is derived which is perpendicular to the Uhuru error box and of similar dimensions. Based on both error boxes, the variable stars most likely to be the X-ray source are found to be V Pup, CN Pup, and CSV 1199.
