Webtransport, and viscous heating on the white dwarf evolution up to the point of helium ignition. Methods. We resolve the structure of the helium accreting white dwarf models with a one dimensional Langrangian hydrody-namic code, modified to include rotational and magnetic effects, in 315 model sequences adopting different mass transfer rates Webdepth required for ignition is achieved more rapidly, and ignition should occur preferentially at this latitude. In fact there are accretion rates where off-equator ignition is still expected. Cooper & Narayan (2007a) considered the situa-tion at high accretion rates ˙m≈ m˙ c3 where helium burning is on the verge of stability.
