A brief examination of the atmosphere of exoplanets

Abstract

As the discovery of exoplanets increased, their characteristics are becoming a main concern for new research. Amongst the many that are discovered, some have an atmosphere of their own just like planet Earth. The purpose of this paper is to examine these atmospheres and calculate the height of the atmosphere using escape velocity. Later in this paper, the issue of the total angular momentum of the planet is examined. This momentum is separated into two different sections whose momentum is added together. The angular momentum of the solid part of the planet is calculated by considering the planet as a rigid body and applying the formula for angular momentum. The second part of calculating the angular momentum is done by using integration to determine the momentum of the atmosphere and using the height of the atmosphere to act as a limit to the definite integral. By understanding the quantities of these exoplanets, further research can be done on how these exoplanets are formed.
