BINARY STARS Meaning and
Definition
-
Binary stars are a celestial phenomenon characterized by a pair of stars that are gravitationally bound to each other and orbit around a common center of mass. These stellar pairs are often referred to as binary systems or double stars.
In a binary star system, the two stars can be of similar or different sizes, masses, and temperatures. They orbit each other in a regular manner due to the gravitational force between them. The period of their orbital motion can vary greatly, from a few hours to several centuries.
There are various types of binary stars, including visual, astrometric, and spectroscopic binaries. Visual binaries are those that can be observed directly with telescopes, as two separate stars in the sky. Astrometric binaries are detected through careful measurements of their combined motion across the celestial sphere, but their individual components cannot be visually resolved. Spectroscopic binaries, on the other hand, reveal their binary nature through periodic shifts in their spectral lines, indicating the Doppler effect caused by their orbital motion.
Binary stars have provided significant insights into our understanding of stellar evolution, mass determination, and galactic dynamics. Their study has contributed to our knowledge of stellar properties, including their masses, sizes, luminosities, and temperatures. Through the observation of binary stars, astronomers can also infer the presence of unseen components such as planets or other stellar remnants. Overall, binary stars play a crucial role in advancing our comprehension of the vast cosmos.

Etymology of BINARY STARS
The word "binary" comes from the Latin word "binarius", which means "composed of two".
The term "binary stars" refers to a system of two stars that orbit around a common center of mass. The concept of binary stars has been known for centuries, but the term itself was first used by English astronomer William Herschel in the late 18th century. Herschel derived the term from the Latin root "bin-" (meaning "two") and combined it with the suffix "-ary" (meaning "associated with"). This combination accurately reflects the nature of the system, consisting of two stars that are associated or connected with each other through their mutual gravitational interaction.
