Hot Jupiters were the first exoplanets to be discovered around main sequence stars and
astonished us with their close-in orbits. They are a prime example of how exoplanets have …

The hierarchical triple-body approximation has useful applications to a variety of systems
from planetary and stellar scales to supermassive black holes. In this approximation, the …

Abstract The Transiting Exoplanet Survey Satellite (TESS) is finding transiting planet
candidates around bright, nearby stars across the entire sky. The large field of view …

We present exoplanet occurrence rates estimated with approximate Bayesian computation
for planets with radii between 0.5 and 16 R⊕ and orbital periods between 0.78 and 400 …

The environment near supermassive black holes (SMBHs) in galactic nuclei contains a large
number of stars and compact objects. A fraction of these are likely to be members of …

About 25 per cent of 'hot Jupiters'(extrasolar Jovian-mass planets with close-in orbits) are
actually orbiting counter to the spin direction of the star. Perturbations from a distant binary …

The secular approximation for the evolution of hierarchical triple configurations has proven
to be very useful in many astrophysical contexts, from planetary to triple-star systems. In this …

In a planetary system with two or more well-spaced, eccentric, inclined planets, secular
interactions may lead to chaos. The innermost planet may gradually become very eccentric …

Context. Several competing scenarios for planetary-system formation and evolution seek to
explain how hot Jupiters came to be so close to their parent stars. Most planetary …

The Kepler spacecraft has discovered a large number of planets with up to one-year periods
and down to terrestrial sizes. While the majority of the target stars are main-sequence dwarfs …
