Post-dynamical inspiral phase of common envelope evolution: Binary orbit evolution and angular momentum transport

Autor: D. Gagnier, O. Pejcha

After the companion dynamically plunges through the primary's envelope, the two cores remain surrounded by a common envelope and the decrease of the orbital period $P_\text{orb}$ stalls. The subsequent evolution has never been systematically explored

Stress-driven spin-down of a viscous fluid within a spherical shell

Autor: D. Gagnier, Michel Rieutord

Publikováno v: Journal of Fluid Mechanics. 904

We investigate the linear properties of the steady and axisymmetric stress-driven spin-down flow of a viscous fluid inside a spherical shell, both within the incompressible and anelastic approximations, and in the asymptotic limit of small viscositie

Autor: Gary A. P. Gibson, D. Gagnier, Jose Fernandez-Triana, C. McCreary, R.M. Labbé, Tara D. Gariepy, R. Hilker, Peter G. Mason

Publikováno v: The Canadian Entomologist. 150:404-411

The pepper weevil,Anthonomus eugeniiCano (Coleoptera: Curculionidae), is the most important pest of pepper (CapsicumLinnaeus; Solanaceae) crops in North America. Native to Mexico, the southern United States of America, and Central America, it is inte

The understanding of the evolution of early-type stars is tightly related to that of the effects of rapid rotation. For massive stars, rapid rotation combines with their strong radiation-driven wind. The aim of this paper is to investigate two questi

The understanding of the rotational evolution of early-type stars is deeply related to that of anisotropic mass and angular momentum loss. In this paper, we aim to clarify the rotational evolution of rapidly rotating early-type stars along the main s

Turbulent transport by diffusive stratified shear flows: from local to global models. Part II: Limitations of local models

Autor: Pascale Garaud, D. Gagnier

This paper continues the systematic investigation of diffusive shear instabilities initiated in Part I of this series. In this work, we primarily focus on quantifying the impact of non-local mixing, which is not taken into account in Zahn's mixing mo
