  So these stars can form dust disks, too? If only I had known it before. I wonder if these disks can form at least smaller planetary bodies.

  Apparently, this object (WISE J085510.83–071442.5) has a planetary-range mass. 3-10 Jupiter masses to be precise. Can anyone confirm is results are preliminary or is the paper accepted?

  Discovery of a wide planetary-mass companion to the young M3 star GU Psc

  This planet has a mass of 9-13 of Jupiter's and orbits 2000 AU from its host star. This is the second widest planetary mass companion at the moment. Its age is rather well constrained which helps a lot at determining its mass.

  Its angular separation is 41 arc seconds which means that the system would take up two pixels in WISE 4 filter. Also, host star is RS Canum Venaticorum variable. Does this means it's actually two stars which would make it a circumbinary planet? Or it it just SIMBAD error?

  Only WD 0806-661 with 2500 AU separation has a larger orbit discovered at the moment.

  A Comprehensive Census of Nearby Infrared Excess Stars

  "The conclusion of the WISE mission presents an opportune time to summarize the history of using excess emission in the infrared as a tracer of circumstellar material and exploit all available data for future missions such as JWST. We have compiled a catalog of infrared excess stars from peer-reviewed articles and perform an extensive search for new infrared excess stars by cross-correlating the Tycho-2 and AllWISE catalogs. We define a significance of excess in four spectral type divisions and select stars showing greater than either 3σ or 5σ significance of excess in the mid- and far-infrared. Through procedures including SED fitting and various image analyses, each potential excess source was rigorously vetted to eliminate false-positives. The infrared excess stars from the literature and the new stars found through the Tycho-2 and AllWISE cross-correlation produced nearly 500 Prime' infrared excess stars and ≥1200 Reserved' stars. The main catalog of infrared excess stars are nearby, bright, and either demonstrate excess in more than one passband or have infrared spectroscopy confirming the infrared excess. This study identifies stars that display a spectral energy distribution suggestive of a secondary or post-protoplanetary generation of dust and they are ideal targets for future optical and infrared imaging observations. The final catalogs of stars summarizes the past work using infrared excess to detect dust disks and with the most extensive compilation of infrared excess stars (∼ 1750) to date, we investigate various relationships among stellar and disk parameters."
