The evolution of a star depends crucially on its initial birth mass and composition, and developments in its early lifetime. These initial properties determine, for example, the production of the chemical elements forged later on in the star's nuclear furnace, and its early angular momentum affects the subsequent distribution of its internal energy.

Einstein's general theory of relativity predicts that accelerating masses should radiate gravity waves in a roughly similar way that accelerating electrical charges radiate electromagnetic (light) waves.

There are now about 1750 confirmed exoplanets, and several thousand candidates awaiting followup measurements. Most of them have been discovered by the Kepler satellite which looks for planetary transits: the slight dimming of starlight when an exoplanet crosses the face of the star as seen from Earth.
