macro_lightning.plot.plot_white_dwarf_constraints(points: Union[None, Sequence] = None, label=False)

Plot Constraints from the existence of massive White Dwarfs.

For sufficiently large cross-sections, the linear energy deposition could produce observable signals if a macro were to pass through compact objects such as white dwarfs in the form of thermonuclear runaway leading to a type IA supernova. These are weaker than previously inferred [2] in important respects because of more careful treatment of the passage of a macro through the white dwarf and greater conservatism regarding the size of the region that must be heated to initiate runaway. On the other hand, more stringent constraints are placed on macros at low cross-section, using new data from the Montreal White Dwarf Database [1].
