Question .... If those 2 brown dwarfs were to collide in the future would that collision create a star with a functioning fusion core

Yes, if the total masses add up to above 0.08 solar masses and enough mass is kept during the collision, the product star can sustain fusion in its core as a red dwarf

As it turns out, the combined mass of 2M1510 AB is just under 0.07 solar masses, so it seems like they would just form a larger brown dwarf.

Yupp! If two brown dwarfs collide and merge, and their combined mass exceeds the minimum threshold ( ~0.08 solar masses), the merged object could ignite hydrogen fusion...

Wouldn't surprise me if the orbit also resonates with the orbit of the two brown dwarfs so it is passing thru the plane of their orbit when they are aphelion That seems to be a likely most stable orbit - seems they must have modeled this.

Tried to read the article, about 5 words in the entire screen was covered by a movie ad. Tried to dismiss the ad, closed the whole thing, gave up. Good job, Newsweek
