Brittle fracture studied by ultra-high speed synchrotron X-ray diffraction imaging
Antoine Petit, Sylvia Pokam, Frederic Mazen +7
Ever since the very first human-made knapped tools, the control of fracture propagation in brittle materials has been a vector of technological development. Nowadays, a broad range…
An integrable model for first-order three-planet mean motion resonances
Antoine C. Petit
Recent works on three-planet mean motion resonances (MMRs) have highlighted their importance for understanding the details of the dynamics of planet formation and evolution. While…
The path to instability in compact multi-planetary systems
Antoine C. Petit, Gabriele Pichierri, Melvyn B. Davies +1
The dynamical stability of tightly packed exoplanetary systems remains poorly understood. While for a two-planet system a sharp stability boundary exists, numerical simulations of…
Resonance in the K2-19 system is at odds with its high reported eccentricities
Antoine C. Petit, Erik A. Petigura, Melvyn B. Davies +1
K2-19 hosts a planetary system composed of two outer planets, b and c, with size of and , and an inner planet, d, with a radius of $1.11\…
Nearly Polar orbit of the sub-Neptune HD3167 c: Constraints on a multi-planet system dynamical history
Shweta Dalal, Guillaume Hébrard, Alain Lecavelier des Étangs +5
We present the obliquity measurement, that is, the angle between the normal angle of the orbital plane and the stellar spin axis, of the sub-Neptune planet HD3167 c, which transits…
High order regularised symplectic integrator for collisional planetary systems
Antoine C. Petit, Jacques Laskar, Gwenaël Boué +1
We present a new mixed variable symplectic (MVS) integrator for planetary systems, that fully resolve close encounters. The method is based on a time regularisation that allows kee…
