Good question. I don't have a clue, other than whatever our solar
wind amounts to times perhaps at least 9 or 10 fold in greater
population of ion particle density/m3, as well as possibly averaging
10 fold in faster exit velocity, making Sirius worth 1000 fold greater
of whatever solar wind pressure/m2 of what our sun can muster. What's
your best SWAG as to the combined Sirius wind?

However, the thought of using a massive solar sail as our retro-break
might be sufficient, especially if having as great as 1e12 m2 of fiber
reinforced mylar sail or disk drag area to work with.
