Abstract:
A field in the Sagittarian bright cloud in the direction of the Galactic
center is investigated by means of the B, V, and R Schmidt plates at the
ESO, and 1165 variable stars are reported. The position, R magnitudes,
epochs, and amplitudes of variation are given for each star, and the
surface density per square degree of variable stars increases from 1.7 to
65. The number of variables in the present field is similar to that for
field A, and variables of type L and/or M are more densely numerous toward
the center of the Galaxy than at other locations. Of the objects listed,
65 are given with potential classifications based on morphological data
from the B and R Schmidt plates. The preliminary observations suggest a
success rate of 42 percent on the precise prediction of the object types.
