Abstract
We have collected initial evidence that tidal interaction between a
late-type star and its close-in, massive planet can lead to a spin-up of
the host star. We propose to explore this further by studying a small
sample of proper motion pairs in which one of the stars is orbited by a
Hot Jupiter. We will determine if the activity-estimated age appears to
be strongly different for the two stars, which would indicate a tidal
spin up of the Hot Jupiter host star. We propose to observe 4 such
systems with Chandra/ACIS-S, and to perform a similar observation of one
additional system with large angular separation using XMM-Newton/EPIC.
The total proposed exposure times are 141 ks (Chandra) and 38 ks (XMM).
