Times of Maxima for the SX Phe star BL Cam
Listed in IVOA Registry (Virtual Observatory)
A total of 73 new times of maximum light for BL Cam were observed through the years 2005 to 2011, which are combined with 1392 times of maxima taken from literature.
Description
A more accurate period of 0.039097912(1) days was found, and an updated linear ephemeris is presented. This newly presented linear ephemeris was used to calculate revised O minus C values, which were fitted with a parabolic curve to measure the rate of change of the pulsation period, found to be (1/P)(dP/dt)=1.37+/-0.02x10^-7yr^-1.
Although the parabolic fit has a physical interpretation, it is noted that a cubic more appropriately fits the behavior of the O minus C diagram.
