SELF-SIMILAR SOLUTIONS OF ADVECTION-DOMINATED ACCRETION FLOWS REVISITED

Chang, Heon-Young    (Department of Astronomy and Atmospheric Sciences, Kyungpook National University  );
  • 초록

    A model of advection-dominated accretion flows has been highlighted in the last decade. Most of calculations are based on self-similar solutions of equations governing the accreting flows. We revisit self-similar solutions of the simplest form of advection-dominated accretion flows. We explore the parameter space thoroughly and seek another category of self-similar solutions. In this study we allow the parameter f less than zero, which denotes the fraction of energy transported through advection. We have found followings: 1. For f > 0, in real ADAF solutions the ratio of specific heats ${\gamma}$ satisfies 1 ${\gamma}$ ${\leq}$ f ${\leq}$ 1. On the other hands, in wind solutions a rotating disk does not exist. 2. For f ${\epsilon}$ greater than zero ${\gamma}$ requires rather exotic range, that is, ${\gamma}$ ${\gamma}$ > 5/3. When -5/2 ${\epsilon}$ ' ${\gamma}$ can be found in ${\gamma}$ 4{\Omega}_0$ ,_ is imaginary. 3. For a negative $u_0$ ,+ with f > 0, solutions are only allowed with exotic ${\gamma}$ , that is, 1 ${\gamma}$ or ${\gamma}$ > (5f/2-5/3)/(5f/2-1)when O ${\gamma}$ 2/5. Since ${\epsilon}$ ' is negative, 4{\Omega}_0$ ,+ is again an imaginary quantity. For a negative $u_0$ ,+ with f ${\gamma}$ is allowed in 1
