A close binary star system occurs when two stars orbit each other with an average separation that is of the same order of magnitude as their diameters. At these distances, more complex interactions can occur, such as tidal effects, transfer of mass and even collisions. Tidal interactions in a close binary … See more Stellar rotation is the angular motion of a star about its axis. The rate of rotation can be measured from the spectrum of the star, or by timing the movements of active features on the surface. The rotation of a … See more Equatorial bulge Gravity tends to contract celestial bodies into a perfect sphere, the shape where all the mass is as close to the center of gravity as possible. … See more After a star has finished generating energy through thermonuclear fusion, it evolves into a more compact, degenerate state. During this process the dimensions of the star are significantly … See more Unless a star is being observed from the direction of its pole, sections of the surface have some amount of movement toward or away from the observer. The component of … See more During formation Stars are believed to form as the result of a collapse of a low-temperature cloud of gas and dust. As the … See more • Staff (February 28, 2006).

WebBinary Stars 1.Optical/apparent: not physical pairs, just a projection effect 2.Physical binaries: bound by gravity (Ekin = Epot), orbiting a common center of mass • Visual or astrometric: the binary is resolved, and the orbit can be mapped via precise astrometry • Eclipsing: orbital plane close to the line of sight, the stars occult each other, as seen in the … WebMay 8, 2024 · In theory, the powerful gravity of this black hole can disrupt binary star systems that stray too close, sending one star rocketing away at about 1000 kilometers per second, fast enough to escape the galaxy's own gravitational pull. Two of Marchetti's stars, however, trace back to outside the galaxy, perhaps to the LMC. freeman laboratories
