cds-question@unistra.frpre-main-sequence-starsstar-forming-regionsradial-velocityproper-motionsvisible-astronomytrigonometric-parallaxinfrared-photometryextinctionWe 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{sun}), 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.2022AJ....163...64Ehttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/163/64CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toVII/233 : The 2MASS Extended sources (IPAC/UMass, 2003-2006)I/345 : Gaia DR2 (Gaia Collaboration, 2018)III/284 : APOGEE-2 data from DR16 (Johnsson+, 2020)I/352 : Distances to 1.47 billion stars in Gaia EDR3 (Bailer-Jones+, 2021)J/ApJS/194/43 : YSOs candidates and knots in CrA cloud (Peterson+, 2011)J/ApJ/746/154 : Improved kinematic parallaxes Sco-Cen members (Pecaut+, 2012)J/ApJ/749/79 : Transition disks.
