Unpoetically named 5737.01, this candidate has an
orbital period of 331 days and is 30 %
larger than Earth, Mullally says.
In July 2008, astronomers (Michael Endl and Martin Kürster) analyzed used seven years of differential radial velocity measurements for Proxima Centauri to submit a paper indicating that
large planets are unlikely to be orbiting Sol's closest stellar neighbor within its habitable zone — around 0.022 to 0.054 AU with a corresponding
orbital period of 3.6 to 13.8 days.
Kepler - 18c and Kepler - 18d have
orbital periods near a 2:1 mean - motion resonance, leading to
large and readily detected transit timing variations.
[Response: Similar to your first point — coherent statistics over time
periods, robust patterns of teleconnections, process by process similarities, coherent emergent properties, quantitative matches in response to
large perturbations (volcanoes,
orbital forcing, continental configurations etc.).
Among them,
large climate oscillations with peak - to - trough amplitude of about 0.1 and 0.251 C, and
periods of about 20 and 60 years, respectively, are synchronized to the
orbital periods of Jupiter and Saturn.
Now, remember that we postulated a very eccentric orbit, this means that the tidal effect will vary greatly and be much
larger when the planet is closest to the star, hence if tides can interfere with or perhaps even control generation of star spots, then the generation of the activity would be synchronized with the
orbital period of the star.
