Abstract:
We have performed a census of the young stellar populations near the
Corona Australis molecular cloud using photometric and kinematic data
from several sources, particularly Gaia EDR3, and spectroscopy of
hundreds of candidate members. We have compiled a catalog of 393
members of Corona Australis, (39 at >M6), 293 (36) of which are
spectroscopically classified for the first time in this work. We find
that Corona Australis can be described in terms of two stellar
populations, a younger one (a few megayears) that is partially
embedded in the cloud (the Coronet Cluster) and an older one (∼15Myr)
that surrounds and extends beyond the cloud (Upper Corona Australis).
These populations exhibit similar space velocities, and we find no
evidence for distinct kinematic populations in Corona Australis, in
contrast to a recent study based on Gaia DR2. The distribution of
spectral types in Corona Australis reaches a maximum at M5
(∼0.15M☉), indicating that the initial mass function has a similar
characteristic mass as other nearby star-forming regions. Finally, we
have compiled mid-infrared photometry from the Wide-field Infrared
Survey Explorer and the Spitzer Space Telescope for the members of
Corona Australis, and we have used those data to identify and classify
their circumstellar disks. Excesses are detected for 122 stars,
one-third of which are reported for the first time in this work.
Description:
We have performed a census of the members of the stellar populations
near Corona Australis using astrometry, photometry, and spectroscopy
from a variety of sources.
