A Period Study for UZ Cygni, VW Cygni, and RX Geminorum
All available times of minimum for UZ Cyg, VW Cyg, and RX Gem were collected and analyzed. The period of VW Cyg decreased suddenly around JD 2417400 by DELTA P/P = -2.9 x 10-5, then remained constant for 1550 cycles, then began increasing steadily. The period of RX Gem decreased suddenly around JD 2427600 by DELTA P/P = -4.1 x 10-5, then began increasing steadily. The 0-- C curve of UZ Cyg was represented with a straight line, that of VW Cyg with two straight lines and a parabola and that of RX Gem with one straight line and a parabola. The last two curves are discussed in the context of the period change model of Biermann and Hall; comparison of the period decrease with the subsequent rate of increase implies that angular momentum is being stored as rotation faster than turbulence can put it back into the orbit.
