Orbital Period of the Moon

2020
The moon moves in an ellipse around the earth itself moving in space, in the same common direction from west to east, which is characteristic of all known planetary bodies of the solar system, with the exception of the Uranus satellites, and likewise many comets.

Orbital period cut-off of W UMa-type contact binaries

, 2020
Period cut-off and period–colour relation are two special characters of W UMa-type contact binaries. In the past, many authors noted these two properties, however, a comprehensive study was still lacking.

Desynchronization by periodic orbits

Physical Review E, 1995
Synchronous chaotic behavior is often interrupted by bursts of desynchronized behavior. We investigate the role of unstable periodic orbits in bursting events and show that they serve as sources of local transverse instability within a synchronous chaotic attractor. Analysis of bursts in both model and experimental studies of two coupled R\"ossler-like

MAGNETIC ACTIVITY AND ORBITAL PERIOD VARIATION OF THE SHORT-PERIOD ECLIPSING BINARY DV Psc

, 2014
We present six new BVRcIc CCD light curves of a short-period RS CVn binary DV Psc obtained in 2010-2012. The light curve distortions change on both short and long timescales, which is explained by two starspots on the primary component.

Following Periodic Orbits [PDF]

open access: possible, 1994
As a parameter of a map is varied, periodic orbits are often seen to appear and shift in position and perhaps period double or blink out of existence. The orbit-following capability is for tracing their behavior as a parameter is varied. The orbit following routine runs for two dimensional maps, including for example the time-2π maps of periodically ...

δ Scuti light variations as a test for choosing the mechanism of cyclic orbital period changes in Algols

, 2012
The temporal behaviour of the orbital period and pulsation period of the δ Scuti type primary component is studied in the eclipsing binary AB Cas, where the secondary fills its Roche lobe. Orbital period changes observed over 80 years are a superposition
