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 WebFeb 11, 2001 · The initial mass function (IMF), i.e. the mass distribution with which individual stars are born, is of fundamental interest in many fields of astronomy …
WebAug 6, 2024 · Let us take the derivative of Eqs.(0.1) and (0.2) to get. and. Substitution yields. Upon making use of the definition of the reduced mass (Eq. (0.3)) we arrive at. If we solve for in Eq.(0.3) we get the total energy of the binary Alpha Centauri A and B. This is true for any binary system assuming center-of-mass coordinates.

Webspectroscopic binary yield the mass function, a combination of the two masses and inclination. This provides a lower limit to the partner mass. Independent measures of the partner star’s mass function and also of orbital tidal light variations or an eclipse duration, if available, can provide the information needed to obtain the masses of ...
