Time-dependent Hypercritical Accretion onto Black Holes
Luca Zampieri
Results are presented from a time-dependent, numerical investigation of super-Eddington spherical accretion onto black holes with different initial conditions. We have studied the…
Search for Old Neutron Stars in molecular clouds: Cygnus Rift and Cygnus OB7
Tomaso Belloni, Luca Zampieri, Sergio Campana
We present the results of a systematic search for old isolated neutron stars (ONSs) in the direction of two giant molecular clouds in Cygnus (Rift and OB7). From theoretical calcul…
Dynamical Comptonization in spherical flows: black hole accretion and stellar winds
R. Turolla, S. Zane, L. Zampieri +1
The transport of photons in steady, spherical, scattering flows is investigated. The moment equations are solved analytically for accretion onto a Schwarzschild black hole, taking…
Time--dependent analysis of spherical accretion onto black holes
Luca Zampieri, John C. Miller, Roberto Turolla
Results are presented from a time--dependent, numerical investigation of spherical accretion onto black holes, within the framework of relativistic radiation hydrodynamics. We have…
