At low densities, when radiation of an accreting gas is dynamically unimportant, quasi-spherical non-radiative accretion flow is formed around a compact object. We show that the density of the flow is n ∝ r −1/2. The gas compression is much weaker than the standard Bondi's, n ∝ r −3/2 , because most of the gas does not reach the compact object. It can either circulate indefinitely long or it ca...

In this paper, we use the result in [7] to calculate the non-Gaussianity of the racetrack models in [3, 5]. Our results show that the nonGaussianity in [3] is reasonable, while the non-Gaussianity in [5] is beyond the observational limits.

The Sun provides an excellent natural laboratory for nonlinear phenomena. We use motions of magnetic bright points on the solar surface, at the smallest scales yet observed, to study the small scale dynamics of the photospheric plasma. The paths of the bright points are analyzed within a continuous time random walk framework. Their spatial and temporal scaling suggest that the observed motions ...
