Query: Constraining the presence of giant planets in two-belt debris disk
  systems with VLT/SPHERE direct imaging and dynamical arguments   Giant, wide-separation planets often lie in the gap between multiple,
distinct rings of circumstellar debris: this is the case for the HR\,8799 and
HD\,95086 systems, and even the solar system where the Asteroid and Kuiper
belts enclose the four gas and ice giants. In the case that a debris disk,
inferred from an infrared excess in the SED, is best modelled as two distinct
temperatures, we infer the presence of two spatially separated rings of debris.
Giant planets may well exist between these two belts of debris, and indeed
could be responsible for the formation of the gap between these belts. We
observe 24 such two-belt systems using the VLT/SPHERE high contrast imager, and
interpret our results under the assumption that the gap is indeed formed by one
or more giant planets. A theoretical minimum mass for each planet can then be
calculated, based on the predicted dynamical timescales to clear debris. The
typical dynamical lower limit is $\sim$0.2$M_J$ in this work, and in some cases
exceeds 1$M_J$. Direct imaging data, meanwhile, is typically sensitive to
planets down to $\sim$3.6$M_J$ at 1'', and 1.7$M_J$ in the best case. Together,
these two limits tightly constrain the possible planetary systems present
around each target, many of which will be detectable with the next generation
of high-contrast imagers.
