WebGlobular clusters are nearly spherical collections of hundreds of thousands of stars, held together by mutual gravitational attraction. These beautiful objects are nearly free of gas and dust, and contain some of the oldest stars in a galaxy. The first stars within these clusters formed at the same time out of the same interstellar nebula, so ...

WebA binary star is a stellar system consisting of two stars orbiting around their center of mass. For each star, the other is its companion star. Recent research suggests that a large percentage of stars are part of systems with at least two stars. Binary star systems are very important in astrophysics, because observing their mutual orbits allows their mass … Formation While it is not impossible that some binaries might be created through gravitational capture between two single stars, given the very low likelihood of such an event (three objects being actually required, as conservation of energy rules out a single gravitating body capturing another) and the high number … See more A binary star is a system of two stars that are gravitationally bound to and in orbit around each other. Binary stars in the night sky that are seen as a single object to the naked eye are often resolved using a See more Methods of observation Binary stars are classified into four types according to the way in which they are observed: visually, by observation; spectroscopically, by periodic changes in spectral lines; photometrically, by changes in brightness … See more A and B The components of binary stars are denoted by the suffixes A and B appended to the system's designation, A denoting the primary and B … See more Double stars, a pair of stars that appear close to each other, have been observed since the invention of the telescope. Early examples include See more The term binary was first used in this context by Sir William Herschel in 1802, when he wrote: If, on the contrary, … See more Orbital periods can be less than an hour (for AM CVn stars), or a few days (components of Beta Lyrae), but also hundreds of thousands of years (Proxima Centauri See more Binaries provide the best method for astronomers to determine the mass of a distant star.

All stars seem to evolve through the red-giant phase to their ultimate state along a straightforward path. In most instances, especially among low-mass stars, the distended outer envelope of the star simply drifts off into … donald rice tires hagerstown md
