| Term | Definition |
|---|---|
| Convective Zone | A region of turbulent plasma between a star's core and its visible photosphere at the surface |
| Radiative Zone | The layer of a star that lies just outside the core |
| Photosphere | the luminous visible surface of the sun, being a shallow layer of strongly ionized gases. |
| Chromosphere | a scarlet, gaseous envelope surrounding the sun outside the photosphere, from which enormous quantities of hydrogen and other gases are erupted. |
| Corona | a faintly luminous envelope outside of the sun's chromosphere, the inner part consisting of highly ionized elements. |
| Sunspot | one of the relatively dark patches that appear periodically on the surface of the sun and affect terrestrial magnetism and certain other terrestrial phenomena. |
| Promenince | an eruption of a flamelike tongue of relatively cool, high-density gas from the solar chromosphere into the corona where it can be seen during a solar eclipse or by observing strong spectral lines in its emission spectrum. |
| Solar Flare | a brief eruption of intense high-energy radiation from the sun's surface, associated with sunspots and causing electromagnetic disturbances on the earth, as with radio frequency communications and power line transmissions. |
| Coronal Mass Injection | a large-scale solar event involving an ejection of hot plasma that may accelerate charged particles and travel as far as the earth's orbit, preceded by a shock front that may create a magnetic storm on earth. |
| Keplers Law | any one of three laws governing planetary motion: each planet revolves in an ellipse, with the sun at one focus |
| Eccentricity | a measure of how an orbit deviates from circular |
| Elliptical Orbit | orbit around the Sun that brings them closer at some times and farther away at others. |
| Formula for Eccentricity | the farthest distance of the orbit to the center of mass of the system, which is a focus of the ellipse). |
| HR Diagram | Hertzsprung Russel Diagram |
| Nebula | a cloud of interstellar gas and dust. |
| Neutron Star | he smallest and densest stars known to exist |
| Black Hole | a region of spacetime exhibiting such strong gravitational effects that nothing—not even particles and electromagnetic radiation such as light—can escape from inside it. |
| Super Nova | a transient astronomical event that occurs during the last stellar evolutionary stages of a massive star's life |
| Protostar | a contracting mass of gas that represents an early stage in the formation of a star, before nucleosynthesis has begun. |
| White Dwarf | a stellar core remnant composed mostly of electron-degenerate matter |
