The performance of the plane-sweep algorithm is superior to a tree code for simulations in which one dimension is much longer than the other two and in simulations which are quasi-two dimensional with less than one million particles.

We discuss the implementation ofJANUS and present tests of its accuracy and speed by performing and analyzing long-term integrations of the Solar System.

Instrumentation and Methods for Astrophysics Cosmology and Nongalactic Astrophysics Earth and Planetary Astrophysics

For planets that are highly misaligned with respect to an eccentric orbit binary, there are stationary (non-oscillating) tilt configurations that are generalisations of polar configurations for the single planet case.

Earth and Planetary Astrophysics

We performed dynamical simulations which establish that the previously identified $\sim800$ d RV signal cannot be attributed to an orbiting body.

The algorithm can handle close encounters and high-eccentricity orbits.

We study the capture of light objects of arbitrary velocity by binary systems.

Solar and Stellar Astrophysics Earth and Planetary Astrophysics High Energy Physics - Phenomenology

Future direct imaging missions will primarily observe planets that have been previously detected, mostly via the radial velocity (RV) technique, to characterize planetary atmospheres.

Earth and Planetary Astrophysics

The new orbital solution and dynamical state of the system confirm migration models that predicted near circular orbits as the preferred scenario.

Earth and Planetary Astrophysics

Impacts onto planets around low-mass stars are found to be very sensitive to the planetary architecture, with the survival of complex prebiotic molecules potentially impossible in loosely-packed systems.

Earth and Planetary Astrophysics

We implement symplectic correctors up to order eleven that significantly reduce the energy error.
