Interesting graphics from NASA in this article. The accretion disc appears to be around the wrong star, with the erupting T CrB occuring in the outer regions of the disc. Wow!
I did a reverse image search and tracked it back to where it was repurposed from in 2010

not that it makes it any better but at least we now know who was to blame !
They actually do also have a decent animation linked from that page showing the accreting system but not the outburst

EDIT the explosion is shown in a further animations down the page
