Molecular physics is apparently quite different in strong magnetic fields, like those on the surface of compact stars. https://www.nature.com/articles/nature.2

Molecular physics is apparently quite different in strong magnetic fields, like those on the surface of compact stars. https://www.nature.com/articles/nature.2012.11045 https://www.nature.com/articles/nature.2012.11045 ("New molecular bonding mechanism predicted in exotic stars’ atmospheres") Maybe one could speculate about a white dwarf star, cooled down to room temperature over astronomical eons, with some sort of life then evolving on its extremely magnetized surface. Its laws of chemistry would work differently.
