Some papers relevant to the recent discoveries on arxiv today. MMT/AO 5 micron Imaging Constraints on the Existence of Giant Planets Orbiting Fomalhaut at ~13-40 AU constrains the existence of other planets in the Fomalhaut system: our results rule out the existence of planets with masses greater than 2 Jupiter masses, from ~13-40 AU and objects greater than 13 Jupiter masses from ~8-40 AU. The HZ of Formalhaut is about 4-6 AU. Direct Imaging of Multiple Planets Orbiting the Star HR 8799 details the imaging of the HR 8799 system, while A Resolved Ring of Debris Dust Around the Solar Analog HD 107146 describes the discovery of another dust disk with a hole in it, similar to the one that lead astronomers to look for planets around Fomalhaut and HR 8799. Their results may imply the presence of a planet at an orbital radius of ~45-75 AU.
