Spectroscopy: The Tool to Study the Stars

Stars are not just useful in the pursuit of astronomy, their importance to us is fundamental. However, the true nature of stars remained a mystery for centuries. Then, through years of hard work we presently do have the tool using which we can actually study and understand the stars. That tool is spectroscopy. For the past few years, intense research in the field of stellar spectroscopy is being carried out at the CHRIST (Deemed to be University) too. This article, written in popular style, provides an understanding of how the exciting field of spectroscopy -- the language of stars -- gradually developed, thus helping humanity to gain a good understanding about stars and astronomy as a whole. The article intends to provide motivation to young students, especially of UG level, who dreams to pursue astronomy research in future to do research in this exciting field.
