Once massive stars leave the main sequence, their evolution is largely set by mass loss through intense radiation-driven winds. Stellar multiplicity has been recognized as a ubiquitous feature: stars seldom live an effectively single life. In the advanced evolutionary stages of a massive binary, mass transfer via stellar winds can become significant and decide the […]
Scattering amplitudes play a central role in our understanding of the fundamental laws of nature. On the one hand they constitute the bridge between theory and experiments, allowing to compute predictions starting from a theoretical model. On the other, they shed light on the underlying properties of quantum field theories. To both ends, analytic results […]

Le CPTGA vous invite à sa 12ème "Journée de Physique Théorique". Le but de ces journées est de permettre des échanges entre physiciens théoriciens de Grenoble/Annecy travaillant dans des domaines très variés. Il est à la fois question de comprendre de la belle science et de découvrir le travail des collègues locaux. Les thèmes de […]
Abstract : The motion of three bodies can be solved perturbatively when a tightly bound inner binary is orbited by a distant perturber on an elliptic orbit. The exchange of angular momentum between the two orbits gives rise to Kozai-Lidov oscillations of eccentricity and inclination characterizing many different systems in astronomy. In this talk, I […]

Warm dark matter (WDM) could explain some small-scale structure observations that have challenged the cold dark matter (CDM) model, as warm particles suppress structure formation due to free streaming effects. Observing small-scale structure thus provides a valuable way to distinguish between CDM and WDM. In this talk, I will present a semi-analytical model for the […]
