Title: Further constraining the nature of the enigmatic Fomalhaut b planet candidate with NICI.
Abstract:
Since its discovery at optical wavelengths with HST, the candidate planet
Fomalhaut b has yet to be independently confirmed; its puzzling photometry
still has not been explained and it still has not been detected in the
near-infrared from the ground or space. In addition, new HST STIS data have
shown that the object may be crossing Fomalhaut's dusty debris belt.
Plausible models to explain the HST data include: light from Fomalhaut
reflected off a dusty disk surrounding a (hypothetical) planet or simply
reflected light from a dust cloud generated as the aftermath of a collision
of two "asteroids" in Fomalhaut's debris belt. We are proposing deep NICI
imaging to (1) obtain the first near-IR detection of the candidate planet,
allowing us to better constrain its SED and confirm if we are seeing only
reflected light or also some thermal emission, and (2) refine the object's
orbit to determine whether it will or will not cross the debris belt.
