The momentum integral can be solved analytically: ∫dpNexp[ − p 2 2mkBT] = (2πmkBT)3N / 2 Thus we have WebDanilov, Vladimir M. Binary stars are present in all stellar systems, yet their role is far from being fully understood. We investigate the effect of unresolved binaries in the derivation of open clusters’ mass by star counts. We start from the luminosity functions of five open clusters: IC 2714, NGC 1912, NGC 2099, NGC 6834, and NGC 7142.

Binary Definition (Illustrated Mathematics Dictionary)

The binary mass function follows from Kepler's third law when the radial velocity of one binary component is known. Kepler's third law describes the motion of two bodies orbiting a common center of mass. It relates the orbital period with the orbital separation between the two bodies, and the sum of their masses. … See more In astronomy, the binary mass function or simply mass function is a function that constrains the mass of the unseen component (typically a star or exoplanet) in a single-lined spectroscopic binary star or in a See more The peak radial velocity $${\displaystyle K}$$ is the semi-amplitude of the radial velocity curve, as shown in the figure.
