Binary star mass function
WebMass function may refer to: Binary mass function, a function that gives the minimum mass of a star or planet in a spectroscopic binary system. Halo mass function, a function that describes the mass distribution of dark matter halos. Initial mass function, a function that describes the distribution of star masses when they initially form, before ... WebWe calculate the mass function of the unseen companions to be between 0.08 and 0.17 M ⊙. Based on the mass function and the estimated stellar parameters of the visible star, we determine the minimum mass of the hidden star. Three targets-J034813, J063350, and J064850-show ellipsoidal variability in the light curves from K2, ZTF, and TESS surveys.

WebMass–luminosity relation. In astrophysics, the mass–luminosity relation is an equation giving the relationship between a star's mass and its luminosity, first noted by Jakob Karl Ernst Halm. [1] The relationship is represented by the equation: where L⊙ and M⊙ are the luminosity and mass of the Sun and 1 < a < 6. [2] Webbinary is the binary mass function. By equating the gravitational force to the cen-tripetal force of either of the components, using various Newtonian relations and …
