Introduction
Exoplanets, or extrasolar planets, are planets that orbit stars outside our solar system. Their discovery has revolutionized our understanding of planetary systems and opened new avenues for studying the potential for life beyond Earth. In this blog, we delve deep into the fascinating world of exoplanets, exploring how they are discovered, classified, and studied, as well as the future prospects of exoplanet exploration.
History of Exoplanet Discovery
The concept of planets orbiting other stars dates back centuries, but it wasn’t until the late 20th century that we had the technology to detect them. The first confirmed detection of an exoplanet was in 1992, when radio astronomers Aleksander Wolszczan and Dale Frail discovered two planets orbiting the pulsar PSR B1257+12. In 1995, Michel Mayor and Didier Queloz made the first discovery of an exoplanet orbiting a main-sequence star, 51 Pegasi b, using the radial velocity method.

Introduction
In aerospace engineering, thermodynamic cycles are the foundation of engine performance analysis and optimization. One of the most critical cycles in this domain is the Brayton Cycle, which describes the operation of gas turbines, jet engines, and modern aircraft propulsion systems. This blog delves deeply into the Brayton Cycle, exploring its stages, principles, equations, and applications in aerospace engineering.
What is the Brayton Cycle?
The Brayton Cycle, named after the American engineer George Brayton, is a thermodynamic cycle that describes the workings of a constant-pressure heat engine. It is the ideal cycle for gas turbine engines, which are widely used in jet engines for aircraft.
Characteristics of the Brayton Cycle
- It is an open cycle in practice but analyzed as a closed cycle in thermodynamics for simplicity.
- Operates on constant pressure processes during heat addition and rejection.
- Consists of four main processes: two isentro...

Introduction
Stars, those magnificent celestial bodies that illuminate the cosmos, have finite lifespans. Their evolution is a complex interplay of forces, culminating in a variety of stellar remnants. Among these, the white dwarf stands as a testament to the powerful forces at work within a star. This blog post will delve into the fascinating world of white dwarfs, exploring their formation, properties, and significance in our understanding of stellar evolution.
The Life and Death of a Star
Before we delve into the specifics of white dwarfs, let’s briefly trace the lifecycle of a typical star.
Stellar Birth
Stars are born from vast clouds of interstellar gas and dust known as nebulae. Gravity pulls these materials together, increasing density and temperature. When the core reaches a critical temperature, nuclear fusion ignites, releasing immense energy and halting further gravitational collapse. This marks the birth of a main-sequence star, like our Sun.
