And we can also study chemical composition and physical parameters of stars, galaxies, nebulae.

Successful models were developed to explain the interiors of stars and stellar evolution.

The oldest accurately dated star chart appeared in ancient Egyptian astronomy in 1534 BC.

Important theoretical work on the physical structure of stars occurred during the first decades of the twentieth century.

A study of the Arches cluster suggests that is the upper limit for stars in the current era of the universe.

The first one, the proton proton chain reaction, is the dominant energy source in stars with masses up to about the mass of the Sun.

These rules of thumb are decidedly inaccurate when describing two or more bodies of similar mass, such as a binary star system (see n body problem).

This is particularly true for very massive O and B class stars, where 80 of the stars are believed to be part of multiple star systems.

This is the number one high resolution, most precise spectrograph on this planet, called HARPS, which is actually used to detect extrasolar planets and sound waves in the atmospheres of stars.
