55 Cancri: A Laboratory for Testing Numerous Conjectures about Planet Formation
Dimitris M. Christodoulou, Demosthenes Kazanas
Five planets are presently believed to orbit the primary star of 55 Cnc, but there exists a large 5 AU gap in their distribution between the two outermost planets. This gap has att…
Simulations of the Poynting--Robertson Cosmic Battery in Resistive Accretion Disks
Dimitris M. Christodoulou, Ioannis Contopoulos, Demosthenes Kazanas
We describe the results of numerical "2.5--dimensional" MHD simulations of an initially unmagnetized disk model orbiting a central point--mass and responding to the continual gener…
Exact Solutions of the Isothermal Lane--Emden Equation with Rotation and Implications for the Formation of Planets and Satellites
Dimitris M. Christodoulou, Demosthenes Kazanas
We have derived exact solutions of the isothermal Lane--Emden equation with and without rotation in a cylindrical geometry. The corresponding hydrostatic equilibria are most releva…
The Cosmic Battery Revisited
Ioannis Contopoulos Demosthenes Kazanas Dimitris M. Christodoulou
We reinvestigate the generation and accumulation of magnetic flux in optically thin accretion flows around active gravitating objects. The source of the magnetic field is the azimu…
Interchange Method in Compressible Magnetized Couette Flow: Magnetorotational and Magnetoconvective Instabilities
Dimitris M. Christodoulou, John Contopoulos, Demosthenes Kazanas
We obtain the general forms of the axisymmetric stability criteria in a magnetized compressible Couette flow using an energy variational principle, the so--called interchange or Ch…
