7 paź 2024 · Binary star, pair of stars in orbit around their common center of gravity. A high proportion, perhaps one-half, of all stars in the Milky Way Galaxy are binaries or members of more complex multiple systems. Some binaries form a class of variable stars, the eclipsing variables.
Examples: Algol in Perseus (every 3 days becomes 3 times dimmer for a few hours); [Delta Velorum, a quadruple star system, whose brightest member is an eclipsing binary; Theta-1 Orionis in the Trapezium]. Astrometric Binaries. How to spot them: We only see one star, but it wobbles due to the presence of the other one.
If one star appears to move in a straight line with respect to the other, it is probable that the two stars are not physically connected but they just happen to lie almost in the same line of sight. Such a pair is called an optical pair or an optical double.
