Hi MAC:
Bitte schau doch einfach mal auf die Seite von HEK :
http://www.cfa.harvard.edu/HEK/publications.html
dort findest du : The Detection and Characterization of a Non-Transiting Planet Through Transit Timing Variations, Science, 336, 1133 [pdf]
und dort findest du :...... As part of the “Hunt for Exomoons with Kepler”
(HEK) project, we report a planetary system with two confirmed planets
and one candidate planet discovered using the publicly available data for
KOI-872. Planet b transits the host star with a period Pb = 33.6 d and exhibits
large transit timing variations indicative of a perturber.
und in dem arxiv :
For transiting planet systems, a companion moon can reveal itself through two categories of observational effects:
Dynamical variations of the host planet.
Eclipse features induced by the moon.
Dynamical effects are measured as perturbations of the
motion of the host planet away from a simple Keplerian
orbit. It is thought that the most observable dynamical
effects will be transit timing and duration variations
(TTV and TDV respectively) (Sartoretti & Schneider
1999; Szab´o et al. 2006; Kipping 2009a,b). Dynamical
effects primarily reveal information about the exomoon
mass.....
Bitte berichtige mich wenn ich hier falsch liege
