Life after stellar death? How life could arise on planets orbiting white dwarfs

"Water isn't a guarantee of life, of course, but even the possibility that previously frozen worlds could be rendered habitable by the death of their star, and then be pulled into a close orbit around that dead star where they can remain habitable, gives astrobiologists a new arena in which to consider alien life. Such a world would be the ultimate case of a "phoenix" world, and prove that there can be life after stellar death.

Becker has a paper describing her work studying the search for habitable planets transiting white dwarfs currently under peer review."

My note. This site shows 6146 exoplanets now, https://exoplanet.eu/home/

The NASA site shows 5671 exoplanets, https://exoplanetarchive.ipac.caltech.edu/index.html

Perhaps some papers will show which of these more than 6,000 exoplanets now has life living on it or evolving from non-living matter. Should be interesting to demonstrate and confirm in science.
