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....
Polarization of the light reflected from exoplanets: A new window into the study of exoplanets
Polarization is an emerging technique in the field of exoplanets. Understanding the basic physics behind the polarization of the light observed from the planets can help us study them in detail. One such aspect is to study the polarization of...
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...
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...
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...
The scientific legacy of Thanu Padmanabhan
Prof. Thanu Padmanabhan, one of the stalwarts of theoretical physics, and a shining star of the Indian scientific community, left his mortal abode on the 17th of September this year. With a stellar career spanning over four decades, he has...
