We use the projected rotational velocity (v sin(i)) estimations reported by the APOGEE-2 collaboration as well as individual masses and ages derived from the position of the stars in the HR diagram, considering Gaia-EDR3 parallaxes and photometry plus diverse evolutionary models. We find an empirical trend for v sin(i) decreasing with age for low-mass stars (0.4M(circle dot) < M-* < 1.2M(circle dot)). Our results support the existence of a mechanism linking v sin(i) to the presence of accreting protoplanetary disks, responsible for regulating stellar rotation on timescales of about 6 Myr, which is the timescale in which most of the T Tauri stars lose their inner disk. Our results provide important constraints to models of rotation in the early phases of evolution of young stars and their disks.Acceso AbiertoANGULAR-MOMENTUM EVOLUTIONMAIN-SEQUENCE STARSLOW-MASS STARSSIGMA-ORIONISYOUNG STARSPHOTOMETRIC VARIABILITYDIFFERENTIAL ROTATIONSPECTRAL-ANALYSISNEBULA CLUSTERVELOCITIESStellar Rotation of T Tauri Stars in the Orion Star-forming Complexhttp://dx.doi.org/10.3847/1538-4357/ac300a
