Observational Manifestations of Precession of Accretion Disk in the SS 433 Binary System,Basic properties of the unique object SS 433 are described. Observational spectroscopic and photometric manifestations of a precessing accretion disk around a relativistic object in this X-ray binary system are presented.Androgen 发表于 2025-3-24 14:58:02
Should Elliptical Galaxies be Idealised as Collisionless Equilibria?,This review summarises several different lines of argument suggesting that one should not expect cuspy nonaxisymmetric galaxies to exist as robust, long-lived collisionless equilibria, ., that such objects should not be idealised as time-independent solutions to the collisionless Boltzmann equation.讨好美人 发表于 2025-3-24 21:58:27
Orbits and Integrals in Self-Consistent Systems,the (1979) computer program. The nonresonant form of the third integral explains the box orbits, while a resonant form of this integral explains both the box orbits and the 1:1 tube orbits. The N-body model gives the distribution of velocities ., which is an exponential of the third integral.离开可分裂 发表于 2025-3-25 03:09:01
Resonantly Excited Non-Linear Density Waves in Disk Systems,n a highly non-linear responses in the disk. Therefore, non-linear theory is a necessity here. We will examine the non-linear theory of resonance excitation and discuss the applications of the theory to Saturn’s rings and disk galaxies in this paper.
