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. The orbital period $${\displaystyle P_{\mathrm {orb} }}$$ is … See more X-ray binaries If the accretor in an X-ray binary has a minimum mass that significantly exceeds the See more In an orbit with eccentricity $${\displaystyle e}$$, the mass function is given by $${\displaystyle f={\frac {M_{2}^{3}\ \mathrm {sin} ^{3}i}{(M_{1}+M_{2})^{2}}}={\frac {P_{\mathrm {orb} }\ K^{3}}{2\pi G}}(1-e^{2})^{3/2}.}$$ See more WebBinary Mass Function. When looking at binary systems in astronomy, we sometimes only possess information about the orbit of one component of the system. This is because …
