Title: Gyrochronology Of Wide Binary Systems

PI: Lares Martiz, Mariel - Embry-Riddle Aeronautical University

Type: SMALL

Summary: Wide binaries are noninteracting coeval pairs of stars that evolve as single stars. They have largely untapped potential to test the empirical rotation-age-mass paradigm known as gyrochronology. New observations of main sequence components of 3296 wide binaries accessible during TESS Cycle 7 are proposed. Our primary goals are to determine whether they follow the same gyrochronology paradigm as cluster stars and to populate the rotation-age-mass relation, especially to ages beyond 1-2 Gyr. Our analysis includes the effects of blended stellar images, light curve systematics, differential rotation, and the identification of occasional spots on opposing hemispheres. The outcome of this project will provide important guidance for improving gyrochronology models.
