Abstract: |
Searches for planets and brown dwarf companions to evolved close
binary stars (e.g., detached WD+dM binaries, sdB-type eclipsing
binaries, magnetic CVs, and X-ray binaries) can provide insight into
the formation and ultimate fate of circumbinary planets and
brown dwarfs, as well as shed light on the late evolution of
binary stars. The eclipse timing method has most successfully been
applied to detect extrasolar planets around binary stars evolved
beyond the first red-giant branch. We have monitored different types of evolved
eclipsing binaries using this method since 2006. In this paper we review
some observational results of circumbinary planets and brown dwarfs
orbiting evolved binaries, especially those orbiting sdB-type
eclipsing binaries. The fate of the Earth in
our solar system is discussed by a comparison of the observational properties
of the close-in substellar objects orbiting sdB-type binaries
with those of planets in our solar system. |
