Confirmation of the changing period of DL Cassiopeiae.

MEYERS C.J.E.

Abstract (from CDS):

An exteded O-C diagram of the Cepheid variable DL Cas confirms that the period has increased. The new parabolic elements are: JD(max)= 2437932.137 + 8.000536 E + 0.000000095 E2. The data do not, hovever, distinguish between the parabolic and other functional forms of the elements.
