The Impact of Hot Jupiters on the Spin-down of their Host Stars
O. Cohen, J. J Drake, V. L. Kashyap +2
We present a numerical Magnetohydrodynamic (MHD) study of the dependence of stellar mass and angular momentum- loss rates on the orbital distance to close-in giant planets. We find…
XMM-Newton observations of HD189733 during planetary transits
I. Pillitteri, S. J. Wolk, O. Cohen +4
We report on two XMM-Newton observations of the planetary host star HD189733. The system has a close in planet and it can potentially affect the coronal structure via interactions…
The Coronal Structure of AB Doradus
O. Cohen, J. J. Drake, V. L. Kashyap +2
We perform a numerical simulation of the corona of the young, rapidly rotating K0 dwarf AB Doradus using a global MHD model. The model is driven by a surface map of the radial magn…
Magnetic Structure of Rapidly Rotating FK Comae-Type Coronae
O. Cohen, J. J. Drake, V. L. Kashyap +3
We present a three-dimensional simulation of the corona of an FK Com-type rapidly rotating G giant using a magnetohydrodynamic model that was originally developed for the solar cor…
