CHARA array The CHARA Array is an optical astronomical interferometer operated by The Center for High Angular Resolution Astronomy (CHARA) of the Georgia State University (GSU).
Chara This star is a yellow-orange main sequence dwarf star of spectral and luminosity type G0 V, with less than 108 percent of Sol's mass, under 111 percent of its diameter, and about 1.2 times its luminosity.
CHARA (Beta Canum Venaticorum). A lovely name for a northern star that vaults the heavens in northern spring, "Chara" from Greek meaning "joy.
Chara is the name assigned either to this star or, more generally, to the "southern hound" of the constellation Canes Venatici; the northern "hound" is called Asterion, a name not generally assigned any particular star.
CHARACTER OF THE SURFACE Martian surface features smaller than 100 kilometres were a matter of pure conjecture until Mariners 4, 6, and 7 returned photographs of the planet in 1965 and 1969.
Character of the surface The character of the Martian terrain has been well established from spacecraft photography and altimetry.
Pulsar Characteristic Age When astronomers measure the period, or spin-rate of the rotation of a pulsar, they find that pulsars are slowing down, usually at a very consistent rate.

CHARACTERISTIC X-RAY - X-ray emitted from an excited atom when an outer-shell (e.g. L) electron jumps in to fill an inner-shell (e.g. K) vacancy. It has energy characteristic of the atom and can therefore be used for analytical purposes.

The characteristic that distinguishes a giant star from a dwarf star is size, which depends on the star's mass and its stage in life. The characteristic that distinguishes a red star from a blue star is temperature.
The characteristic of type 1a supernovae that make them standard candles is that low redshift supernovae with similar durations and spectra have similar peak luminosities. Those observed at low redshift can be calibrated with Cepheid variables.
One characteristic of astronomy which tends to make its progress slow and continuous arises out of the general fact that, except in the case of motions to or from us, which can be determined by a single observation with the spectroscope, ...

A galaxy characterized by a moderately bright, compact active galactic nucleus, presumably powered by a black hole. Shock Wave A high-pressure wave that travels at supersonic speeds. Shock waves are usually produced by an explosion.
Light has characteristics of a wave (understand the properties of waves) and a particle, the photon. Light is a continuum of radiant energy. Describe the complete spectrum of light. Blackbody radiation is an important type of light emission.
All these characteristics are compatible with the conclusion that stars of these classes are all of similar chemical composition and are arranged in a temperature order from hottest to coolest.

The crater near the top of the photo has a sunlit central peak, which was a common characteristic of craters on Dione in Voyager images.
Each "flavor" of light is characterized by a particular wavelength. The visible spectrum is composed of light of different colors (the rainbow colors) and the wavelengths of this light ranges from about 700 nanometers to 400 nanometers.
Characteristic frequencies or "spectral lines" emitted by atoms usually have very sharply defined wavelengths--but if the light originates in a hot gas, the wavelength range is broadened, because the emitting atoms are in constant motion.
Physical and Orbital Characteristics The first table lists some of the physical and orbital characteristics of the planets. Obliquity measures the angle of inclination of the equator to the orbital plane.
Within a group there may be one or more families of asteroids whose orbital characteristics are so much alike that they almost certainly came from the breakup of a single parent body.
This activity is designed for use after students have become familiar with the names and characteristics of the eight planets in our solar system.
