Time of Maxima for the SX Phe star XX Cyg
Listed in IVOA Registry (Virtual Observatory)
XX Cyg is a High Amplitude {delta} Scuti star which has been extensively studied because of its changing period.
Description
We present 64 new times of maxima which have been combined with 174 times of maxima from literature, in order to give an updated ephemeris and O-C plot for XX Cyg. Its period, currently found to be 0.134865117(3) days, is shown to be increasing continuously, which has lead to a new calculated value of (1/P)(dP/dt)=(1.33+/-0.09)10^-8^yr^-1^
