Spitzer Telescope observes baby brown dwarf
Yousuf Khan
"NASA's Spitzer Space Telescope has contributed to the discovery of the
youngest brown dwarf ever observed -- a finding that, if confirmed, may
solve an astronomical mystery about how these cosmic misfits are formed."

Perhaps Sirius(c) has been a brown dwarf, or that of a very dense
stellar remainder.
Dead white dwarfs might suggest our universe is older than thought.

Otherwise, a white dwarf may simply terminate sooner than thought.

Yes, if your desperately-sought Sirius-C existed, then most likely it is
a brown dwarf or a planet. It wouldn't be a red dwarf, white dwarf,
neutron star or black hole, as they are all easily detectable in various
ways, especially in a multi-star solar system.
You do realize that none of these stories you've linked to have anything
to do with what your narrative is, right? Yes, of course you do, this is
your hobby, take a story and completely mix it up somehow with something
it's got nothing to do with.

The first two links are talking white dwarfs are already dead stars,
they're not talking about finding something deader than a white dwarf.
These articles are talking about finding debris around white dwarfs,
such as dust and asteroids and planets. It's hardly surprising, the
white dwarfs blow off their outer atmospheres when they die, so the
material may coalesce back into dusty debris.

The third story is not talking about a white dwarf terminating, they're
simply talking about a white dwarf accreting material off a companion,
to become a Type Ia supernova.
