Non-Axisymmetric Instabilities in Self-Gravitating Star-Disk Systems: Bifurcation of Rapidly Rotating Protostars

Tumblin, Rebecka (University of Oregon, 2021-11-23)

The nonlinear evolution of three-dimensional protostars surrounded by circumstellar disks are numerically investigated to understand the conditions under which short-period binary star systems could form and to probe ...
Optimal Constrained Interest-rate Rules

Evans, George W., 1949-; McGough, Bruce (University of Oregon, Dept of Economics, 2005-05-19)

We show that if policy-makers compute the optimal unconstrained interest-rate rule within a Taylor-type class, they may be led to rules that generate indeterminacy and/or instability under learning. This problem is compounded ...
