Given our (racial) tendancy for stupidity I'd tend to assume we'll not be around for that long.

Although it does make me realize that establishing colonies on planets in this solar system is not enough to "ensure" our survival...

Hmmm

Well I'm exceptionally sceptical about this. OK, so its been a good 12 (maybe 10) yrs since I stoppped looking at AstroP, and far be for me to question what a great ind from Harvard may have to say, but how the feck does one think that the second start in the binary system will feel after the dwarf reaches enough mass to collapse to a neutron star, and thus goes nova? The outer layers of the second start would almost certainly be blown away. Now, a nova is nothing to be sniffed at, but it has nothing like the explosive force of a supernova. So I'd be moderately interested to see how our chappie has dealt with this stage in his scenario. HOwever, I have hardly enough time to even think about this atm - but it has tweaked my interest, and I may take a bigger look at it. Post main-sequence stellar evolution and early universe cosmology always were my favourite AstroP subjects (altho' LJ would not let me list the former as an interest - too many letters one suspects).

According to the New Scientist article the dwarf is very close to the i-go-supernova-now limit, and that when its companion runs out of fuel and becomes a red giant the outer layers of the companion would probably be plenty enough to push it over the edge.
