that's some planet, huh? or maybe it just says something about the quality of stars in their neighborhood...
Role Reversal: Planet Controls a Star
all right, i've been meaning to post something about this for a while, now. space.com covered it, and i'll bet you could dig up something at nasa.
in a unique discovery, made possible by the special equipment and procedures at canada's most space telescope, astronomers realised that in a particular system, tau bootis, an enormous planet has actually locked it's parent star, gravitationally speaking, of course.
i don't think they quite understand why it happened the way it did, but the scientists compared the movement to the way the moon turns just slowly enough so that the light side always faces earth.
i guess it just goes to show how much more we've got to learn about our universe.
