What is an "Epistellar Jovian Exoplanet"?

These are the planets of roughly Jupiter mass that have been found near the stars 51 Pegasi, 55 Cancri, Tau Bootes and Upsilon Andromidae with orbits that are within 0.1 Astronomical Units of the main star. These are also called 'blow torch orbits' because the planetary temperatures get up to 1000 F during portions of the orbits. Tau Bootis C orbits within 8 stellar radii of the star and must be a very weird world indeed! For more details about the recently detected planets visit Planet Search.
