Subsonic wind accretion

Subsonic wind accretion

The rate of subsonic wind accretion (accretion on a point Newtonian mass moving through uniform gas) is shown to be independent of the wind velocity and equal to the spherical Bondi rate - for the adiabatic index equal to 5/3. A (very accurate) numerical calculation of the accretion flow, confirming...

Description
Summary:The rate of subsonic wind accretion (accretion on a point Newtonian mass moving through uniform gas) is shown to be independent of the wind velocity and equal to the spherical Bondi rate - for the adiabatic index equal to 5/3. A (very accurate) numerical calculation of the accretion flow, confirming this result, is also presented. © 2022 The Author(s) Published by Oxford University Press on behalf of Royal Astronomical Society.
