A minimal model for vertical shear instability in protoplanetary accretion disks
Ron Yellin-Bergovoy, Eyal Heifetz, Orkan M. Umurhan
The Vertical Shear Instability is an axisymmetric effect suggested to drive turbulence in the magnetically inactive zones of protoplanetary accretion disks. Here we examine its phy…
On the physical mechanism of centrifugal-gravity wave resonant instability in swirling free surface rotating Polygons
Ron Yellin-Bergovoy, Eyal Heifetz, Orkan M. Umurhan
We present an explicit analysis of wave-resonant instability of swirling flows inside fast rotating cylindrical containers. The linear dynamics are decomposed into the interaction…
On the mechanism of self gravitating Rossby interfacial waves in proto-stellar accretion discs
Ron Yellin-Bergovoy, Eyal Heifetz, Orkan M. Umurhan
The dynamical response of edge waves under the influence of self-gravity is examined in an idealized two-dimensional model of a proto-stellar disc, characterized in steady state as…
