Figure 5. MEGNO stability maps superimposed on an upper mass-limit function of a hypothetical perturber. A MEGNO of around 2 indicates quasi-periodic (regular) orbits. A MEGNO of 5 or larger indicates ...
The Nature Index 2026 Research Leaders reveal the leading institutions and countries/territories in the natural sciences, health sciences, applied sciences and social sciences, according to their ...
Transiting exoplanets in multi-planet systems have non-Keplerian orbits which can cause the times and durations of transits to vary. The theory and observations of transit timing variations (TTV) and ...
A new investigation into old Kepler data has revealed that a planetary system once thought to house zero planets actually has two planets that orbit their star in a unique style, like an old-fashioned ...

Following on from Paper I in our series (Xie 2012), we report the confirmation by Transit Timing Variations (TTVs) of a further 30 planets in 15 multiple planet systems, using the publicly available ...
Scientists from UNSW Sydney have located a potential new exoplanet – a planet that orbits a star outside of our solar system – using a technique known as ‘transit timing variation’. In research ...
