Further Constraints on the Presence of a Debris Disk in the Multiplanet System Gliese 876; Journal article

摘要

Using both the Very Large Array (VLA) at 7 mm wavelength, and the Australia Telescope Compact Array (ATCA) at 3 mm, we have searched for microwave emission from cool dust in the extrasolar planetary system Gliese 876 (Gl 876). Having detected no emission above our 3 sigma detection threshold of 135 microJy, we rule out any dust disk with either a mass greater than 0.0006 Earth mass or less than.
