Scientists are constantly finding new ways to look at things, and that’s especially true for objects that represent an outlier of their specific type. Adjectives like “biggest”, “brightest”, or “fastest spinning” all seem to attract scientific studies - perhaps because they’re an easier sell to funding agencies. No matter the reason, that means we typically get a lot of good science on specific objects that represent their particular class of objects well, and a new paper from Ozcan Caliskan from Istanbul University in Turkey hits that nail on the head when it comes to the most massive known white dwarf star.
