Polar Coronal Holes: Contrasting Rigid and Latitudinal Solar Rotation

Project Description:

The Sun’s photosphere exhibits differential rotation, with a sidereal period of approximately 25 days at the solar equator and 34 days at the poles. However, polar coronal holes, which are located at latitudes higher than 80 degrees, rotate rigidly around the Sun’s magnetic axis with a period of about 27 days. This project aims to measure the rotation rates of coronal holes, analyze their distribution across different latitudes, and examine their area variations. Additionally, the rotation rates of coronal holes will be compared with the rotation rates of the photosphere to investigate potential relationships and patterns.
