A star is a massive, luminous ball of plasma that is held together by gravity. The nearest star to Earth is the Sun, which is the source of most of the energy on Earth. Other stars are visible in th...

7. Which important stellar parameter can be determined by the study of binary stars? (a) the age of the stars; (b) surface temperatures of the stars; (c) the distance of the stars from Earth; (d) stellar masses; 8. Where do we find the most massive stars on the main sequence in a Hertzsprung-Russell diagram?

b. in elliptical orbits, about a common "center of mass" 52. An eclipsing binary system is a. two stars which periodically eclipse each other, as seen from Earth 53. Binary stars, mutually bound to each other by gravitational forces, allow us to derive which important stellar parameter a. stellar mass 54.

In fact, it can only be determined directly if the star happens to be gravitationally bound to another star in a binary stellar system. Observations of the orbital motions of the two stars as they circle each other allows to "weigh" them, and also provide other important information, e.g. about their sizes and temperatures.

The Formation of Binary Stars ... Finally, as we have grown to appreciate, dynamical processes that prove to be important in the context of evolved, close binary star systems often prove to be important in the binary formation problem as well. ... The study of tidal and mass-transfer instabilities in close binary star systems.
