ABSTRACT
The physical properties and orbits of planetary systems are believed to undergo various changes even after their formation. Determining the ages of stars is essential for statistically studying such evolution. A useful method for this is gyrochronology, which utilizes the relationship between stellar rotation and age. While this rotation-age relationship has been extensively studied for relatively young low-mass stars in open clusters through quasi-periodic brightness variations in broad-band photometry data, there is still limited information for stars older than the Sun. In this talk, I will present our recent work that provides insights into the rotational evolution of older Sun-like stars, focusing on (i) the selection function of rotation periods derived from photometric observations, and (ii) a statistical analysis of high-resolution spectroscopy data to derive the rotation period distribution avoiding biases against photometrically quiet stars.
