WebThe light curves of different kinds of variable stars differ in the degree of change in magnitude (i.e., the amount of light flux observed), in the degree of regularity from one cycle to the next, and in the length of the cycle—i.e., the period. 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

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 ...
