Query: The dense cores and filamentary structure of the molecular cloud in
  Corona Australis. Herschel SPIRE and PACS observations from the Herschel
  Gould Belt Survey   We present a catalogue of prestellar and starless cores within the Corona
Australis molecular cloud using photometric data from the Herschel Space
Observatory. At a distance of d~130 pc, Corona Australis is one of the closest
star-forming regions. Herschel has taken multi-wavelength data of Corona
Australis with both the SPIRE and PACS photometric cameras in a parallel mode
with wavelengths in the range 70 {\mu}m to 500 {\mu}m. A complete sample of
starless and prestellar cores and embedded protostars is identified. Other
results from the Herschel Gould Belt Survey have shown spatial correlation
between the distribution of dense cores and the filamentary structure within
the molecular clouds. We go further and show correlations between the
properties of these cores and their spatial distribution within the clouds,
with a particular focus on the mass distribution of the dense cores with
respect to their filamentary proximity. We find that only lower-mass starless
cores form away from filaments, while all of the higher-mass prestellar cores
form in close proximity to, or directly on the filamentary structure. This
result supports the paradigm that prestellar cores mostly form on filaments. We
analyse the mass distribution across the molecular cloud, finding evidence that
the region around the Coronet appears to be at a more dynamically advanced
evolutionary stage to the rest of the clumps within the cloud.
