Binary star light curve
Webits light curve, reveals a great deal about its physical properties. Astronomers can use light curves to determine the size, mass, temperature, and even the distance to a star system. Today, we'll look at the light curves of two types of variable stars, and discuss exactly what sort of measurements http://spiff.rit.edu/classes/phys370/lectures/eclipse_1/eclipse_1.html

WebWe derived the binary mass ratio M G /M B = 0.17 ± 0.03 based on the assumption that the G-type secondary fills its Roche lobe and rotates synchronously. Using this value of the mass ratio as well as the radial velocities of the G-star, we obtained a consistent light curve model and improved estimates of the stellar masses, radii, luminosities ... WebThese curves plot the radial velocities of two stars in a spectroscopic binary system, showing how the stars alternately approach and recede from Earth. Note that positive …
