Effects of Turbulence, Eccentricity Damping, and Migration Rate on the Capture of Planets into Mean Motion Resonance
planetary systems planetary systems formation — planets and satellites formation — turbulence
2010/11/11
Pairs of migrating extrasolar planets often lock into mean motion resonance as they drift inward. This paper studies the convergent migration of giant planets (driven by a circumstellar disk) and dete...
Damping of longitudinal magneto-acoustic oscillations in slowly varying coronal plasma
magnetohydrodynamics(MHD) - plasmas - Sun corona - waves
2010/11/15
We investigate the propagation of MHD waves in a homogenous, magnetized plasma in a weakly
stratified atmosphere, representing hot coronal loops. In most of earlier studies a time-independent equilib...
Spatial Damping of Linear Compressional Magnetoacoustic Waves in Quiescent Prominences
Sun: prominences oscillations magnetohydrodynamics radiation thermal
2010/9/17
We study the spatial damping of magnetoacoustic waves in an unbounded quiescent prominence invoking the technique of MHD seismology. We consider Newtonian radiation in the energy equation and derive a...
Damping of Slow Magnetoacoustic Waves in an Inhomogeneous Coronal Plasma
Sun corona—active region—coronal loops—TRACE—MHD waves—heating
2010/9/16
We study the propagation and dissipation of slow magnetoacoustic waves in an inhomogeneous viscous coronal loop plasma permeated by uniform magnetic field. Only viscosity and thermal conductivity are ...

We modified oscillator strengths and enhancement factors of van
der Waals damping constants for 84 moderately strong and weak neutral iron spec-
tral lines between 500 nm and 510 nm, by fitting the ...
