Extrasolar planets: The one that got away
Jonathan Fortney1
Abstract
Hanging around a star that has passed through its red-giant phase doesn't seem a likely place for a planet. But one planet apparently managed to avoid being engulfed by its bloated star — might others, too?
One of the most surprising things that we have learnt about planets during the past 15 years is that they can turn up almost anywhere. On page 189 of this issue, Silvotti et al.1 expand our planet-finding horizon still farther: they have discovered a massive gas-giant planet orbiting an old star in a rare, late stage of the star's evolution.
