Begleitsternen

Begleitsternen, which translates to "companion stars," refers to stars that orbit another star. These celestial pairs or multiples are a common phenomenon in the universe. The gravitational interaction between the stars dictates their orbital paths. The masses of the stars are a primary factor in their orbital period and distance. If the stars are close together, they may significantly influence each other's evolution, potentially leading to mass transfer or even the destruction of one of the stars. Binary star systems are the most basic form of begleitsternen, consisting of two stars. However, systems can comprise three or more stars, known as multiple star systems. The study of begleitsternen is crucial for understanding stellar evolution, determining stellar masses, and even measuring astronomical distances. Observations of begleitsternen have provided invaluable data that has advanced our knowledge of celestial mechanics and the life cycles of stars. Many stars visible to the naked eye are, in fact, binary or multiple systems where the individual components are too close to be resolved without telescopic aid.
