This GitHub Organization holds all the projects that are a part of the Gyrochronology project at Embry-Riddle Aeronautical University, led by Dr. Terry Oswalt (principal investigator) and Dr. Derek Buzasi (co-principle investigator, based in FGCU).

Researchers on this project are comprised of undergraduates and graduates, working on various sub-projects.

Gyrochronology is the empirical relation between a star's rotation rate and its age. For stars on the main sequence (MS stars) of spectral type $F\to M$, gyrochronology may accurately measure stellar ages for stars roughly $0.6$ to $1.0$ solar masses.

The paradigm, Gyrochronology, which has been calibrated using solar-type stars and white dwarfs in open clusters, can be one of the better tools for determining the ages of the main sequence and white dwarf stars. The main physical theory that surrounds this project is known as Gyrochronology. It is a theory based on determining the age of low-mass, main-sequence (MS) stars. MS stars with low masses are said to be at the beginning of the main part of their lives. A star's time in the main sequence marks their adult life as a star. Pre-main sequence stars are still in the development stages of becoming a star and have not yet reached the criteria for becoming main sequence stars.
