Extrasolar Planets: October 2019

Future space telescopes may be able to directly image ∼10 - 100 planets with sizes and orbits consistent with habitable surface conditions ("exo-Earth candidates" or EECs), but observers will face difficulty in distinguishing these from the potentially hundreds of non-habitable "false positives" which will also be detected.

We explore here the prospects for detection of both giant circumbinary exoplanets, and brown dwarfs orbiting Galactic double white dwarfs binaries (DWDs) with the LISA mission.
