Stellar dynamics is an area of astronomy devoted to understanding the physical processes that create and rotate the heavenly bodies.
There are six known subparts of stellar dynamics. They are stellar mass, stellar atmosphere, stellar environment, stellar evolution and the stellar wind. All of these parts play important roles in the creation of the universe. This field of study has great relevance in our understanding of the cosmos. Studying stellar dynamics can be of great help in the search for evidence of the Big Bang Theory, the origin of the universe, supernovae explosions, gamma-ray bursts, black holes, pulsars and other celestial phenomena.
Stellar dynamics is a branch of astronomy that studies the collective movement of celestial bodies in space as a result of their mutual attraction and gravity.
The main difference between stellar mechanics and general astronomy is that each celestial body gives off equal amounts of radiation and mass, while in general astronomy each is created on its own. In stellar dynamics, stellar matter consists primarily of hydrogen and helium, with many other types of elements making up the bulk of the substance. Stellar mass also includes ice, metal and rock grains, while non-planetary matter makes up a relatively small fraction of the total stellar content. The main difference between the two is that in general terms a large galaxy will contain a greater concentration of rocky gas than a smaller galaxy.
Stellar evolution is the study of stellar dynamics within a larger evolutionary system.
It attempts to explain how the stellar system evolved through the stages it has already undergone. Different theories have been postulated to explain this, with some being more accurate than others. The best theory so far proposed is the Einstein-Rosenfield theory, which postulates that the growth and stability of a stellar system is primarily affected by gravitational forces acting on a handful of extremely heavy stars.
Plasma physics is the study of the effects of plasma, or gas, particles on a planetary or stellar surface.
There are two broad schools of thought regarding the relationship between stellar dynamics and plasma physics. The first believes that stellar fields are shaped by plasma particles, while the second assumes that only a Planck mass of plasma can actually create such forces. There are many discrepancies between the two, however, including the fact that plasma particles do not have a complete charge, which results in them having an extremely high density.
Stellar evolution is also tied to the relative formation of various stellar systems within our own Milky Way, as well as other nearby galaxies.
A variety of models have been postulated to explain the evolution of these systems, including the bulge and accretion theories. The bulge, also called the “galaxy-mass” model, explains why spiral Galactose are so common, while elliptical curves and disks are not. The accretion model, also called the “solar-mass” model, postulates that stellar systems form in clumps and tend to collapse into themselves. The last, the flat hyperbola conjecture, postulates that the very shape of space-time must be curved in some unique way, resulting in the formation of very compact clusters of stars.
As space-time is curved by these models, stellar systems form different equations which must be solved for a cohesive field to emerge.
The equations must also take into consideration the effects of spiral and bulge components, as well as the effects of interactions with other atomic elements, and their effect on the spiral movement itself. All of these questions have had a variety of answers over the years, ranging from completely straightforward, to very complicated approximations, to completely wrong solutions.
The most accurate model for stellar dynamics, and therefore the best method of describing the evolution of galaxies and their stars, is a numerical study known as Monte Carlo simulation. This technique was originally designed to solve other problems involving probability distributions, and has since been applied in many scientific areas, including stellar evolution, to great success. This is why it has become an important tool in the field of astronomy. It is also why many of the problems astronomers are currently struggling with, including black holes, white holes, and the mysteries of quasars, have been effectively addressed by numerical studies.
There are many other potential models for stellar dynamics, including stellar nuclei, disks of gas, and perturbations at different points in the universe. Some models make great approximations, while others completely fail to explain the data. Most models however, have succeeded in explaining the most important features of spiral structure, formation, and evolution in our Galaxy and beyond.
