Abstract
Some previous results concerning pressure effects in line accretion should be ignored, as they are based on an inadequate Bernoulli equation. The behavior of velocity (density) is studied in the vicinity of the stagnation, singular and asymptotic points, also collecting together the results spread throughout the literature for isothermal and pressure-free flows. The cut-off distance of the accretion column and the resulting gravitational drag on the velocity of the accretor are found from a unified condition on the boundary pressure.
