Astronomy  Chaotic rotation  Charge-Coupled Device

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.

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.

Chara - β Canum Venaticorum (Beta Canum Venaticorum, β CVn)
Beta CVn is the second brightest star in Canes Venatici. It is a G-type main sequence dwarf approximately 27.4 light years from Earth.

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.

Flare Characteristics
Solar flares are tremendous explosions on the surface of the Sun. In a matter of just a few minutes they heat material to many millions of degrees and release as much energy as a billion megatons of TNT.

Field characteristics
The field is similar to that of a bar magnet, but this similarity is superficial.
