The mutual inclination of a planetary system—the angle between the orbital planes of neighbouring planets—encodes information about its formation history. However, measuring mutual inclinations ...

We present new ways to identify single and multiple moons around extrasolar planets using planetary transit timing variations (TTVs) and transit duration variations (TDVs). For planets with one moon, ...

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 ...

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 ...

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 ...

Brown dwarf exoplanet system TOI-201 c is the longest-period transiting object ever confirmed by radial velocity, and the ...

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 ...

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 ...

TOI-1136, a dwarf star located more than 270 light years from Earth, is host to six confirmed exoplanets and a seventh as yet unconfirmed candidate. The system has provided a rich source of ...

The Kepler mission and its extension, called K2, discovered thousands of exoplanets. It detected them using the transit technique, measuring the dip in light intensity whenever an orbiting planet ...
