Soft X-rays from the intermediate-age open cluster NGC 752.
BELLONI T. and VERBUNT F.
Abstract (from CDS):
A ROSAT PSPC observation of NGC 752 detects 49 sources. Seven sources are tentatively identified with optical cluster members, of which three are short-period binaries, one is a blue straggler, and one a rapid rotator. The eclipsing binary DS And - also a cluster member - is probably detected as well. The X-ray properties of these sources are similar to those of RS CVn binaries with the same absolute magnitude and colour in the galactic disk.
