The Ongoing Decline in Activity of Comet 103P/Hartley 2
Ariel Graykowski, Guillaume Langin, David Chiron +102
We report photometric observations of Comet 103P/Hartley 2 during its 2023 apparition. Our campaign, conducted from August through December 2023, combined data from a global networ…
A uniqueness result for the two vortex travelling wave in the Nonlinear Schrodinger equation
David Chiron, Eliot Pacherie
For the Nonlinear Schrodinger equation in dimension 2, the existence of a global minimizer of the energy at fixed momentum has been established by Bethuel-Gravejat-Saut. This minim…
Coercivity for travelling waves in the Gross-Pitaevskii equation in for small speed
David Chiron, Eliot Pacherie
In the previous paper, we constructed a smooth branch of travelling waves for the 2 dimensional Gross-Pitaevskii equation. Here, we continue the study of this branch. We show some…
Smooth branch of travelling waves for the Gross-Pitaevskii equation in for small speed
David Chiron, Eliot Pacherie
We construct a smooth branch of travelling wave solutions for the 2 dimensional Gross-Pitaevskii equations for small speed. These travelling waves exhibit two vortices far away fro…
From Vlasov-Poisson and Vlasov-Poisson-Fokker-Planck Systems to Incompressible Euler Equations: the case with finite charge
Julien Barré, David Chiron, Thierry Goudon +1
We study the asymptotic regime of strong electric fields that leads from the Vlasov-Poisson system to the Incompressible Euler equations. We also deal with the Vlasov-Poisson-Fokke…
Stability and instability for subsonic travelling waves of the Nonlinear Schrödinger Equation in dimension one
David Chiron
We study the stability/instability of the subsonic travelling waves of the Nonlinear Schrödinger Equation in dimension one. Our aim is to propose several methods for showing instab…
