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…
Soft coronal X-rays from β Pictoris
H. M. Günther, S. J. Wolk, J. J. Drake +3
A type stars are expected to be X-ray dark, yet weak emission has been detected from several objects in this class. We present new Chandra/HRC-I observations of the A5 V star β Pic…
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…
