Document Summary
A light curve tells the relative brightness of stars. A light curve tells the relative brightness of stars missing info. Use kepler"s laws to measure the masses. We see combined from both lights but its changes with time due to orbit of stars. When they are side by side - brightness is at a maximum. When one star is in front - brightness is reduced. When one star is behind - brightness is at a minimum (we only see brightness from 1) We look for the hydrogen triplet that is always moving together. Versus when the least massive stars turn into giants and supergiants. A star"s luminosity is proportional to its size and temperature. What differentiates the bright stars and cold stars is the mass of the star. Fusion of he c + o then nitrogen, silicon until iron (if star is capable) What is left after cores are shed is the core is the white dwarf.
