12 M92 variables Photographic observations

Listed in IVOA Registry (Virtual Observatory)

The periods and the light curves of 12 variable stars of the globular cluster M92 have been studied analyzing 176 plates obtained with the 60 cm reflector of Bologna Observatory from 1964 to 1966.

Description

Combining the results of the present observations with Hachenberg's (1925, 1933, 1934) and Nassau's (1936), the periods were improved and the O-C diagrams for 9 variables were traced. A parabola well represents the residuals of the variables No. 3, 8 and 11.

Variable 9 is likely not strictly periodic.
