White Dwarfs Form Exceptional Habitable Conditions for Exoplanets

Competing studies at work.
The best things about white dwarves are the incredible stability, and the long duration expected.
the worst thing? They only get worse with time.
But at least it takes a long time.

And then, the God Emperor annexes it.

The existence of a White Dwarf implies that any planets have had their atmospheres and oceans stripped off.

The existence of a White Dwarf implies that any planets have had their atmospheres and oceans stripped off.

Implies but does not ensure. A strong enough magnetic field can retain some. Various processes can result in new atmosphere. And the more eccentric orbits are more likely to be affected by the blast – those on an inbound leg when the supernova happens will get slowed or reversed, making it possible to get a fresh run of comets, and hence also volatiles.
