Most Extreme Stars

A general article exploring some of the most extreme stars of the universe. Each one of them deserves the word ‘most’ for varied reasons. Just read and enjoy the mysterious cosmos sitting at home.


Magnetic Field Measurements of the Solar Corona by Aditya L1

One of the science goals of the Aditya L1 is to map the coronal magnetic field topology. The infrared channel of the VELC payload of the Aditya L1 is equipped with a spectropolarimeter to perform full stokes spectropolarimetric observations in...


Identification of a new category of stars: stars in rare transition phase found

Pre-main-sequence (PMS) stars evolve into the main-sequence (MS) phase over a period of time. Interestingly, we found a scarcity of studies in the existing literature that examine and attempt to better understand the stars in the PMS to MS transition...


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...
