celestial equator
... equator. It is a projection of the Earth's equator out to the celestial sphere. The number of degrees that a celestial object is north or south of the celestial equator is called the declination (DEC) It is the analogue of latitude on the sky. The analogue of longitude is called right ascension (RA) ...

M = 5.5 - The Millstone
... Absolute Magnitude, we must have a measure of the stellar distance (by other means). Absolute magnitude, M, expresses the brightness of a star as it would be if it were placed 10 parsecs away. Since all stars would be placed at the same distance, absolute magnitudes show differences in actual lumino ...

TAP 702- 6: Binary stars - Teaching Advanced Physics
... In many binary stars, the two stars are not perfectly lined up when seen from Earth. This means that there will not be any dimming or brightening of the light, because the dimmer star will not block out the light from the brighter one. How might an astronomer tell, from the spectrum, that there are ...
