cds-question@unistra.frstellar-associationsstellar-spectral-typesline-intensitiesradial-velocityinfrared-photometryvisible-astronomyproper-motionsastronomical-object-identificationx-ray-sourcesI have used the third data release of the Gaia mission to improve the reliability and completeness of membership samples in the {beta} Pic moving group (BPMG) and other nearby associations with ages of 20-50Myr (Sco Body, Carina, Columba, {chi}^1^ For, Tuc-Hor, IC 2602, IC 2391, NGC 2547). I find that Carina, Columba, and {chi}^1^ For are physically related and coeval, and that Carina is the closest fringe of a much larger association. Similarly, Tuc-Hor and IC 2602 form a coeval population that is spatially and kinematically continuous. Both results agree with hypotheses from Gagne+ 2018, J/ApJ/856/23. I have used the new catalogs to study the associations in terms of their initial mass functions, X-ray emission, ages, and circumstellar disks. For instance, using the model for Li depletion from Jeffries+ 2023MNRAS.523..802J, I have derived an age of 24.7_-0.6_^+0.9^Myr for BPMG, which is similar to estimates from previous studies. In addition, I have used infrared photometry from the Wide-field Infrared Survey Explorer to check for excess emission from circumstellar disks among the members of the associations, which has resulted in a dramatic increase in the number of known disks around M stars at ages of 30-50Myr and a significant improvement in measurements of excess fractions for those spectral types and ages. Most notably, I find that the W3 excess fraction for M0-M6 initially declines with age to a minimum in BPMG (<0.015), increases to a maximum in Carina/Columba/{chi}^1^ For (0.041_-0.007_^+0.009^, 34Myr), and declines again in the oldest two associations (40-50Myr). The origin of that peak and the nature of the M dwarf disks at >20Myr are unclear.2024AJ....168..159Lhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/168/159CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toB/sb9 : SB9: 9th Catalogue of Spectroscopic Binary Orbits (Pourbaix+ 2004-2014)B/ocl : Optically visible open clusters and Candidates (Dias+ 2002-2015)III/117 : MK Classifications of Close Visual Binaries (Corbally, 1984)III/123 : Dwarf K and M stars of small proper motion (Stephenson 1986)III/150 : Perkins Revised MK Types for the Cooler Stars (Keenan+ 1989)III/182 : HDE Charts: positions, proper motions (Nesterov+ 1995)III/198 : Palomar/MSU nearby star spectroscopic survey (Hawley+ 1997)II/328 : AllWISE Data Release (Cutri+ 2013)II/335 : Revised cat. of GALEX UV sources (GUVcat_AIS GR6+7) (Bianchi+ 2017)I/352 : Distances to 1.47 billion stars in Gaia EDR3 (Bailer-Jones+, 2021)III/286 : APOGEE-2 DR17 final allStar catalog (Abdurro'uf+, 2022)I/355 : Gaia DR3 Part 1.
