cds-question@unistra.frstellar-associationsinfrared-astronomyWe present stellar rotation rates derived from Transiting Exoplanet Survey Satellite (TESS) light curves for stars in Upper Centaurus-Lupus (UCL; ~136pc, ~16Myr) and Lower Centaurus-Crux (LCC; ~115pc, ~17Myr). We find spot-modulated periods (P) for ~90% of members. The range of light-curve and periodogram shapes echoes that found for other clusters with K2, but fewer multiperiod stars may be an indication of the different noise characteristics of TESS, or a result of the source selection methods here. The distribution of P as a function of color as a proxy for mass fits nicely in between that for both older and younger clusters observed by K2, with fast rotators being found among both the highest and lowest masses probed here, and a well-organized distribution of M-star rotation rates. About 13% of the stars have an infrared excess, suggesting a circumstellar disk; this is well matched to expectations, given the age of the stars. There is an obvious pileup of disked M stars at P~2days, and the pileup may move to shorter P as the mass decreases. There is also a strong concentration of disk-free M stars at P~2days, hinting that perhaps these stars have recently freed themselves from their disks. Exploring the rotation rates of stars in UCL/LCC has the potential to help us understand the beginning of the end of the influence of disks on rotation, and the timescale on which stars respond to unlocking.2022AJ....164...80Rhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/164/80CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toB/mk : Catalogue of Stellar Spectral Classifications (Skiff, 2009- )B/gcvs : General Catalogue of Variable Stars (Samus+, 2007-2017)II/240 : The DENIS database first release (Epchtein+, 1999)I/297 : NOMAD Catalog (Zacharias+ 2005)I/305 : The Guide Star Catalog, Version 2.3.2 (GSC2.3) (STScI, 2006)I/320 : SPM 4.0 Catalog (Girard+, 2011)I/347 : Distances to 1.33 billion stars in Gaia DR2 (Bailer-Jones+, 2018)I/345 : Gaia DR2 (Gaia Collaboration, 2018)II/361 : MDFC Version 10 (Cruzalebes+, 2019)IV/38 : TESS Input Catalog - v8.0 (TIC-8) (Stassun+, 2019)II/366 : ASAS-SN catalog of variable stars (Jayasinghe+, 2018-2020)I/353 : The Guide Star Catalog, Version 2.4.2 (GSC2.4.2) (STScI, 2020)I/352 : Distances to 1.47 billion stars in Gaia EDR3 (Bailer-Jones+, 2021)VII/233 : The 2MASS Extended sources (IPAC/UMass, 2003-2006)J/A+AS/128/561 : UBVRI photometry of southern T Tauri stars (Batalha+ 1998)J/AJ/117/354 : OB associations from Hipparcos (de Zeeuw+, 1999)J/A+A/468/1039 : VRIJK photometry of GQ Lup (Broeg+, 2007)J/MNRAS/385/1749 : UNSW catalog of Variable Stars (Christiansen+, 2008)J/A+A/500/1045 : Cool stars and brown dwarfs in Lupus clouds (Comeron+, 2009)J/A+A/520/A15 : RACE-OC project; YSOs within 100pc (Messina+, 2010)J/A+A/532/A10 : RACE-OC project.
