- Context: The 125th anniversary of Kodaikanal Solar Observatory (KSO) was celebrated recently on April 1, 2024, by the Indian Institute of Astrophysics (IIA)
- Significant achievements of KoSO
- Identified the Evershed Effect (a phenomenon observed in sunspots where gas flows radially outward from the centre of the sunspot)
- Expanded research scope to cosmic rays, radio astronomy, ionospheric physics, and stellar physics
- The Evershed Effect refers to the radial flow of gas across the solar surface in sunspots. As sunspots are areas of intense magnetic activity on the Sun’s surface, the magnetic fields cause gases to flow radially outward from the center of the sunspot. This effect was discovered by the English astronomer John Evershed in the early 20th century. Options A, B, and C describe other astronomical phenomena but do not accurately represent the Evershed Effect.

Which of the following statements regarding the Evershed Effect is tru...
Explanation:
Overview of the Evershed Effect:
The Evershed Effect is a phenomenon observed in sunspots, which are dark regions on the Sun's surface caused by intense magnetic activity.
Description of the Evershed Effect:
- The Evershed Effect refers to the radial flow of gas across the solar surface within sunspots.
- This flow of gas is observed to move outward from the center of the sunspot, suggesting a motion of material from the center towards the outer regions.
Explanation of the Correct Statement:
The statement "It is observed as a radial flow of gas across the solar surface in sunspots" is true because the Evershed Effect specifically describes this radial flow of material within sunspots. This flow is a result of the magnetic field's influence on the dynamics of the gas in these regions.
In conclusion, the Evershed Effect is related to the radial flow of gas within sunspots on the Sun's surface, and it is not related to other phenomena such as the deflection of light in a magnetic field or Doppler shifts in stellar spectra.
