Hot Jupiters and Hot Spots: The Short- and Long-term Chromospheric Activity on Stars with Giant Planets
E. Shkolnik, G. A. H. Walker, D. A. Bohlender +2
We monitored the chromospheric activity in the Ca II H & K lines of 13 solar-type stars (including the Sun); 8 of them over three years at the CFHT and 5 in a single run at the VLT…
The Internal Structural Adjustment due to Tidal Heating of Short-Period Inflated Giant Planets
Pin-Gao Gu, Peter H. Bodenheimer, Douglas N. C. Lin
Several short-period Jupiter-mass planets have been discovered around nearby solar-type stars. During the circularization of their orbits, the dissipation of tidal disturbance by t…
The Effect of Tidal Inflation Instability on the Mass and Dynamical Evolution of Extrasolar Planets with Ultra-Short Periods
Pin-Gao Gu, Doug Lin, Peter Bodenheimer
We investigate the possibility of substantial inflation of short-period Jupiter-mass planets, as a result of their internal tidal dissipation associated with the synchronization an…
Vorticity Budget of Weak Thermal Convection in Keplerian disks
Pin-Gao Gu
By employing the equations of mean-square vorticity (enstrophy) fluctuations in strong shear flows, we demonstrate that unlike energy production of turbulent vorticity in nonrotati…
