... Two bright planets and the brightest stars share the evening sky this May. Soon after sunset golden Jupiter appears in the northeast. Beside Jupiter is Spica, the brightest star in Virgo. Below Jupiter, near the horizon, is orange Arcturus, the brightest star in the northern sky. As the sky darkens ...

... This is a good time to emphasize that the light curve is showing normalized flux and that as we change the radius of a star we are changing the value of the total flux. If you now decrease the radius of star 1 the eclipses will get deeper until the two stars have the same radius (Example 1) and then ...

EVOLUTION OF A SOLAR
... The Life and Death of a Sun-like Star These notes describe the evolutionary path taken by a Sun-like star, one with an initial mass comparable to the Sun’s mass. Stars can be thought of as a series of nested shells, surrounding a core. The core is more dense, hotter, and at higher pressure than the ...
