发帖数: 330 | 1 Astronomers from McMaster University in Hamilton, Ontario find that "dead
zones"- which typically extend out to 13 astronomical units from the central
star of an extrasolar planetary system - can significantly slow planetary
migration so that planets are not lost to the systems. This release
summarizes work to be described in a press conference at the American
Astronomical Society meeting in Calgary, Alberta on June 5, 2006, and in an
invited talk at a scientific session during the meeting.
