Astronomers from the Indian Institute of Astrophysics (IIA) Map the Differential Rotation of the Sun's Chromosphere Using 100 Years of Kodaikanal Data.

Science and Technology | Dated: 06 Oct 2024

Astronomers from Indian Institute of Astrophysics (IIA) mapped the Sun's differential rotation, revealing the equator rotates faster than poles, enhancing solar activity understanding.

🎯 Key Highlights:

  • - The discovery was based on 100 years of daily records from Kodaikanal, Tamil Nadu (TN).

💡 Other Important Facts:

  • (i) This study is the first to utilize chromospheric network cells for mapping the Sun's rotation across different latitudes.
  • (ii) The analysis found that the Sun rotates fastest at the equator (13.98 degrees per day) and slows toward the poles (10.5 degrees per day at 80 degrees latitude).
