On the Mathematical Character of the Relativistic Transfer Moment Equations
R. Turolla, L. Zampieri, L. Nobili
General--relativistic, frequency--dependent radiative transfer in spherical, differentially--moving media is considered. In particular we investigate the character of the different…
On the Nature of Photospheric Oscillations in Strong X--Ray Bursts
Iosif Lapidus, Luciano Nobili, Roberto Turolla
A possible sound origin for the photospheric oscillations in the X--ray bursting sources 1608-522 and 2127+119 is suggested. It is shown that standing sound waves in an expanding s…
Accretion Rates in X--Ray Bursting Sources
Iosif Lapidus, Luciano Nobili, Roberto Turolla
We present estimates for the accretion rates in 13 X--ray bursting sources which exhibit photospheric expansion, basing on theoretical models of stationary, radiatively driven wind…
Winds from Neutron Stars and Strong Type I X--Ray Bursts
Luciano Nobili, Roberto Turolla, Iosif Lapidus
A model for stationary, radiatively driven winds from X--ray bursting neutron stars is presented. General relativistic hydrodynamical and radiative transfer equations are integrate…
