Description Follow-up Herschel observations have recently confirmed the presence
of a resolved debris disk around GJ 581, a nearby M star with 4 low-mass
(super-Earth) planets. Debris disks around M stars are exceedingly rare
(virgul1% detection rate in the DEBRIS survey), raising the question of whether
the debris might somehow be directly related to the neighboring planets.
In order to assess whether low-mass planets are strongly correlated
with dusty debris or whether this is just a chance coincidence, we propose
to dramatically increase the number of planet-bearing M stars observed
by Herschel, from the current 3 up to a total of 20 stars. The proposed
PACS 100/160 um images of 17 planet-bearing M stars will clarify
whether this class of system preferentially has orbiting debris.
Should any new disks be detected, the close proximity of the target
M stars (virgul10 pc) makes them favorable candidates for resolved imaging,
which may help to explain the unusual asymmetry in GJ 581.s
similarly resolved disk.

Mission Description Herschel was launched on 14 May 2009! It is the fourth 'cornerstone' mission in the ESA science programme. With a 3.5 m Cassegrain telescope it is the largest space telescope ever launched. It is performing photometry and spectroscopy in approximately the 55-671 µm range, bridging the gap between earlier infrared space missions and groundbased facilities.
