Reversible time-step adaptation for the integration of few-body systems
Tjarda C. N. Boekholt, Timothee Vaillant, Alexandre C. M. Correia
The time step criterion plays a crucial role in direct N-body codes. If not chosen carefully, it will cause a secular drift in the energy error. Shared, adaptive time step criteria…
Developing a data fusion concept for radar and optical ground based SST station
Bruno Coelho, Domingos Barbosa, Miguel Bergano +4
As part of the Portuguese Space Surveillance and Tracking (SST) program, a tracking radar and a double Wide Field of View Telescope system (4.3° x 2.3°) are being installed at the…
Chasing extreme planetary architectures: I- HD196885Ab, a super-Jupiter dancing with two stars?
G. Chauvin, M. Videla, H. Beust +21
Planet(s) in binaries are unique architectures for testing predictions of planetary formation and evolution theories in very hostile environments. We used the IRDIS dual-band image…
A direct N-body integrator for modelling the chaotic, tidal dynamics of multi-body extrasolar systems: TIDYMESS
Tjarda C. N. Boekholt, Alexandre C. M. Correia
Tidal dissipation plays an important role in the dynamical evolution of moons, planets, stars and compact remnants. The interesting complexity originates from the interplay between…
Dynamics of co-orbital exoplanets in a first order resonance chain with tidal dissipation
Jérémy Couturier, Philippe Robutel, Alexandre C. M. Correia
Co-orbital planets (in a mean motion resonance) can be formed within a Laplace resonance chain. Here, we develop a secular model to study the dynamics of the resonance chain…
Photodynamical analysis of the nearly resonant planetary system WASP-148: Accurate transit-timing variations and mutual orbital inclination
J. M. Almenara, G. Hébrard, R. F. Díaz +23
WASP-148 is a recently announced extra-solar system harbouring at least two giant planets. The inner planet transits its host star. The planets travel on eccentric orbits and are n…
