Orbital period changes in WZ Sagittae
We report a long-term (1961-2017) study of the eclipse times in the dwarf novae WZ Sagittae, in an effort to learn its rate of orbital-period change. Some wiggles with a timescale of 20-50 years are apparent, and a connection with the ~23 year interval between dwarf-nova eruptions is possible. These...

| Sumario: | We report a long-term (1961-2017) study of the eclipse times in the dwarf novae WZ Sagittae, in an effort to learn its rate of orbital-period change. Some wiggles with a timescale of 20-50 years are apparent, and a connection with the ~23 year interval between dwarf-nova eruptions is possible. These back-and-forth wiggles dominate the O-C diagram, and prevent a secure measurement of the steady rate of orbital-period change. |
