An efficient integrator for stellar dynamics in effective gravity fields based on the isochrone potential
Alexandre Bougakov, Melaine Saillenfest, Marc Fouchard
Context. Integrating the motion of stars in a smoothed potential is necessary in many stellar and galactic studies. Previous works have often used numerical integrators that altern…

Explanation of the exceptionally strong timing noise of PSR J0337+1715 by a circum-ternary planet and consequences for gravity tests
Guillaume Voisin, Ismaël Cognard, Melaine Saillenfest +6
Context: Timing of pulsar PSR J0337+1715 provides a unique opportunity to test the strong equivalence principle (SEP) with a strongly self-gravitating object. This is due to its un…
