Deciphering The Mysteries of The Quiet Sun Explosions

XSM onboard Chandrayaan 2 observed the Sun during its minimum activity period in 2019-2020. Using this data, the researchers have for the first time detected a very large number of small scale explosions, called microflares, happening on the Sun. The...


The First Theoretical Model of the Near-Surface Shear Layer of the Sun

It is well known that the Sun rotates differentially, i.e. its equator rotates faster than the pole. Not only at the surface, but the solar rotation profile also varies with the radius, which was discovered in helioseismic observation. This observation...


Classical Ae stars: What are they? Why study them?

Starting from the history of star classification in the millinniums, this interesting note will take you through some of the very basic concepts on emission-line stars. You will be able to understand what they are and why these type of...


Twinkle twinkle little stars, should I wonder what you are? A brief account of variable stars

Curiosity is what has driven mankind to observations of new phenomena. Every twinkling star in the night sky is definitely not due to the atmospheric refraction of earth. Rather, one might be looking at a variable star, each with a...


Technical aspects of VELC onboard ADITYA-L1: India’s first solar space mission

This article is the review of a journal paper on the Visible Emission Line Coronagraph, the primary payload onboard India’s first solar space mission, ADITYA-L1. The paper discusses some technical details of VELC and the work done in analyzing them....


From Sun to Earth using Artificial Intelligence

The focus of this article is solar wind. I first take the reader through the theory & observations, and various properties of solar wind. Then, I take a detour through machine and deep learning which form the basis of our...
