"So if WD 1856 can make it to this ...To estimate whether WD 1856 b could have survived this phase of strong EUV evaporation at its current position, we use simple scaling laws for hydrodynamic escape. For large EUV fluxes, mass loss due to hydrodynamic escape can be in the energy-limited or the recombination-limited regime.

1 INTRODUCTION The vast majority of the stars in the Galaxy, including our Sun and virtually all known planet hosts, will end their lives as white dwarfs. It is now well established that planets can survive the transformation of their host star into a white dwarf (Villaver & Livio 2007; Mustill & Villaver 2012; Rao et al. 2018; Ronco et al. 2020 ).WD 1856+534 is a white dwarf located in the constellation of Draco. At a distance of about 25 parsecs (80 ly) from Earth, it is the outer component of a visual triple star system consisting of an inner pair of red dwarf stars. …
