Binary stars pdf
WebConsider two stars isolated from all other stars. If we can ignore the internal structure of the stars then: • Total energy = Potential energy + Kinetic energy is conserved • If Etotal < 0: stars are bound (don’t need to form a binary - we have one already!) • If Etotal > 0: stars are unbound and will remain so http://physics.usyd.edu.au/~helenj/SeniorAstro/lecture11.pdf

Habitability of binary star systems is determined by many factors from a variety of sources. Typical estimates often suggest that 50% or more of all star systems are binary systems.This may be partly due to sample bias, as massive and bright stars tend to be …
