Main Sequence Stars
... • The idea of the “Vogt-Russell” theorem for stars is that there is only one way to make a star with a given mass and chemical composition – if we start with a just formed protostar of a given mass and chemical composition, we can calculate how that star will evolve over its entire life. • This is e ...

Effects of Mutual Transits by Extrasolar Planet
... Figure 1 shows light curves by mutual transits for two cases. One is the zero spin limit of ω → 0 as a reference. In this case, motion of the two objects is nothing but a translation. Because of the time lag between the first and second transits, a certain plateau appears in light curves. The other ...
