Stellar Dynamos
A Parameter Space Study

Andrés Muñoz Jaramillo








Abstract:

Stars are known to exhibit a wide variety of magnetic activity.  Presumably, this activity is produced by a hydromagnetic dynamo mechanism operating in the interior of the Star.  The purpose of this study is to investigate how the nature of a Star's magnetic output depends on physical processes which consitute the dynamo mechanism, such as differential rotation and circulation.  The dynamo mechanism has been studied extensively in the context of the Sun.  We take this experience gained from the solar dynamo mechanism and build upon it to do a parameter space study with the idea of establishing scaling laws between various observable physical quantities of Stars.  Such a theoretical study when complemented with observations of stellar magnetic activity may provide insight on how the magnetic dynamo evolves with changing conditions in the interior of a Star, at various phases of a Star's lifetime.
