Exact Relativistic Static Charged Dust Disks and Non-axisymmetric Structures
The well-known “displace, cut and reflect” method used to generate disks from given solutions of Einstein field equations is applied to the superposition of two extreme Reissner-Nordström black holes to construct disks made of charged dust and also non-axisymmetric planar distributions of charged dust on the z = 0 plane. They are symmetric with respect to two or one coordinate axes, depending w...
متن کاملIn pursuit of structures in protoplanetary disks
This brief summarizes work devoted to studying the linear stability of baroclinic protoplanetary Keplerian disks. This work largely builds on the foundation and fundamental results obtained by Barranco, Marcus & Umurhan (2000) (hereafter BMU) which presented a model to describe structures in weakly baroclinic Keplerian disks. Interest in protoplanetary disks has grown since the discovery of the...
متن کاملOn the Commonality of 10-30au Sized Axisymmetric Dust Structures in Protoplanetary Disks
An unsolved problem in step-wise core-accretion planet formation is that rapid radial drift in gasrich protoplanetary disks should drive mm-/meter-sized particles inward to the central star before large bodies can form. One promising solution is to confine solids within small scale structures. Here we investigate dust structures in the (sub)mm continuum emission of four disks (TW Hya, HL Tau, H...
متن کاملOn the width and shape of gaps in protoplanetary disks
Although it is well known that a massive planet opens a gap in a proto-planetary gaseous disk, there is no analytic description of the surface density profile in and near the gap. The simplest approach, which is based upon the balance between the torques due to the viscosity and the gravity of the planet and assumes local damping, leads to gaps with overestimated width, especially at low viscos...
متن کاملInterferometric Detection of Planets/Gaps in Protoplanetary Disks
We investigate the possibility to find evidence for planets in circumstellar disks by infrared and submillimeter interferometry. Hydrodynamical simulations of a circumstellar disk around a solar-type star with an embedded planet of 1 Jupiter mass are presented. On the basis of 3D radiative transfer simulations, images of this system are calculated. These intensity maps provide the basis for the...
