... After a short period the luminosity stabilizes, and since Lnuc < L, the star responds by having its envelope contract. That contraction leaves the luminosity unchanged, but moves the star to higher effective temperature. The motion is roughly horizontal in the HR diagram, so this is known as the hor ...

Binary evolution in a nutshell
... Here we made the assumption that the fraction of the stellar mass available for hydrogen fusion is the same for all stars. In reality, this factor will vary; it is ∼ 0.15 for the Sun, but may be much larger for more massive stars, for example because they have convective cores and can mix material f ...
