Extrasolar Planets: December 2006

An international team of researchers including NAI Postdoctoral Fellow Evgenya Shkolnik of the University of Hawai'i Team publish their observation in this month's Royal Astronomical Society Letters of a magnetic field at the surface of star Tau Bootis, which is orbited by a giant planet every three days. The magnetic field's intensity is similar to that of the Sun, but the star and the planet are tidally locked, possibly producing the observed magnetic knots. [Source: NAI Newsletter]
