Fomalhaut, a bright star 7.7 parsecs (25 light-years) from Earth, harbors a belt of cold dust with a structure consistent with gravitational sculpting by an orbiting planet. Here, we present optical observations of an exoplanet candidate, Fomalhaut b. Fomalhaut b lies about 119 astronomical units (AU) from the star and 18 AU of the dust belt, matching predictions of its location. Hubble Space Telescope observations separated by 1.73 years reveal counterclockwise orbital motion. Dynamical models… Expand
Infrared Non-detection of Fomalhaut b: Implications for the Planet Interpretation
The nearby A4-type star Fomalhaut hosts a debris belt in the form of an eccentric ring, which is thought to be caused by dynamical influence from a giant planet companion. In 2008, a detection of aExpand
Correlations between the stellar, planetary, and debris components of exoplanet systems observed by Herschel
Context. Stars form surrounded by gas- and dust-rich protoplanetary discs. Generally, these discs dissipate over a few (3–10) Myr, leaving a faint tenuous debris disc composed of second-generationExpand
A gap in the planetesimal disc around HD 107146 and asymmetric warm dust emission revealed by ALMA
While detecting low-mass exoplanets at tens of au is beyond current instrumentation, debris discs provide a unique opportunity to study the outer regions of planetary systems. Here, we report newExpand
New HST data and modeling reveal a massive planetesimal collision around Fomalhaut
TLDR
It is found that Fomalhaut b has faded in brightness and grown in extent, with motion consistent with an escaping orbit, and suggestions that the source is a dispersing cloud of dust, produced by a massive collision between two planetesimals in an extrasolar planetary system are confirmed. Expand
DIRECT IMAGING OF A COLD JOVIAN EXOPLANET IN ORBIT AROUND THE SUN-LIKE STAR GJ 504
Several exoplanets have recently been imaged at wide separations of >10?AU from their parent stars. These span a limited range of ages ( 0.5?mag), implying thick cloud covers. Furthermore,Expand
Direct imaging of irregular satellite discs in scattered light
Direct imaging surveys have found that long-period super-Jupiters are rare. By contrast, recent modeling of the widespread gaps in protoplanetary disks revealed by ALMA suggests an abundantExpand
THE LICK-CARNEGIE SURVEY: A NEW TWO-PLANET SYSTEM AROUND THE STAR HD 207832
Keck/HIRES precision radial velocities of HD 207832 indicate the presence of two Jovian-type planetary companions in Keplerian orbits around this G star. The planets have minimum masses of Msin i =Expand
A RESOLVED DEBRIS DISK AROUND THE CANDIDATE PLANET-HOSTING STAR HD 95086
Recently, a new planet candidate was discovered on direct images around the young (10–17 Myr) A-type star HD 95086. The strong infrared excess of the system indicates that, similar to HR8799, β Pic,Expand
PLANETS AND DEBRIS DISKS: RESULTS FROM A SPITZER/MIPS SEARCH FOR INFRARED EXCESS
Using the MIPS camera on the Spitzer Space Telescope, we have searched for debris disks around 104 stars known from radial velocity studies to have one or more planets. Combining this new data withExpand
