1C Astronomy Vocab-ESPS

Convective Zone The region of the sun's interior that is between the radiative zone and the photo sphere and in which energy is carried upward by convection.
Radiative Zone A very dense region of the sun in which the atoms are so closely packed that light can take millions of years to pass through.
Photosphere The inner layer of the sun's atmosphere.
Chromosphere A gaseous layer of the sun's atmosphere (extending from the photosphere to the corona) that is visible during a total eclipse of the sun.
Corona The outermost layer of the sun's atmosphere.
Sunspot A dark area of gas on the sun's surface that is cooler than surrounding gases.
Prominence A loop of gas that protrudes from the sun's surface, linking parts of sunspot regions.
Solar Flare An eruption of gas from the sun's surface that occurs when the loops in sunspot regions suddenly connect.
Coronal mass ejection A large explosion of matter and energy from the Sun.
Kepler's Law A theory compromised of laws that describe the planetary movement around the sun.
Eccentricity Something or someone strange and unconventional behavior.
Elliptical Orbit An oval shaped path, used to describe the shape of the Earth's orbit around the Sun.
Formula for eccentricity The distance between foci divided by length of major axis.
Solar System Sun, planets, and all the other objects that revolve around the sun
Astronomy The study of the moon, stars, and other objects in space
HR Diagram Classifies stars by temperature and absolute brightness
Nebula A large cloud of dust and gas in space, the beginning of a star.
Stellar Spectra based on absorption lines: O B A F G K M; surface temperature sequence (hot to cool)
Red Giant A star that expands and cools once it runs out of hydrogen fuel
White Dwarf Stage in which a star has used up its helium and its outer layers escape into space, leaving behind a hot, dense core that contracts
