The effect of limited spatial resolution of stellar surface magnetic field maps on MHD wind and coronal X-ray emission models
C. Garraffo, O. Cohen, J. J. Drake +1
We study the influence of the spatial resolution on scales of and smaller of solar surface magnetic field maps on global magnetohydrodynamic solar wind models, and on a model…
The Cosmic Ray Intensity Near the Archean Earth
O. Cohen, J. J. Drake, J. Kota
We employ three-dimensional state of the art magnetohydrodynamic models of the early solar wind and heliosphere and a two-dimensional model for cosmic ray transport to investigate…
Ambipolar Electric Field, Photoelectrons, and their Role in Atmospheric Escape From Hot-jupiters
O. Cohen, A. Glocer
Atmospheric mass-loss from Hot-jupiters can be large due to the close proximity of these planets to their host star and the strong radiation the planetary atmosphere receives. On E…
The Role of White Dwarfs in Cataclysmic Variable Spin-down
O. Cohen, J. J. Drake, V. L. Kashyap
We study the effect of a white dwarf on the spin-down of a cataclysmic variable system using a three-dimensional magnetohydrodynamic numerical model. The model includes the stellar…
