Dark Matter's Invisible Sparks: Tiny Black Holes as Stellar Detonators ✦
Original: "Primordial Black Hole Triggered Type Ia Supernovae II: Comparison with Supernova Remnants and Galactic Chemical Evolution"
Asteroid-mass primordial black holes are not just invisible dark matter, but also triggers for Type Ia supernovae, rewriting the chemical history of galaxies.

A ghost asteroid pierces a star—and it flares brighter than a hundred billion suns. Perhaps primordial black holes not only hide in dark matter but also act as a detonator for white dwarfs. Their invisible trails are preserved in the chemical chronicles of stars. Someday, decoding it, we will map the unseeable itself.
🎯 An asteroid-mass primordial black hole, piercing a white dwarf, releases so much heat that it triggers a thermonuclear explosion, yet emerges unscathed from the stellar inferno and continues wandering the galaxy.
T_{\text{ign}} \approx 5 \times 10^8 \, \text{K}
Carbon ignition temperature: half a billion kelvins—the price of starting a thermonuclear fire in a white dwarf.
10^{-17} M_{\odot} \lesssim M_{\text{PBH}} \lesssim 10^{-12} M_{\odot}
PBH detonator masses: from asteroid to small moon—these are the “bullets” capable of blowing up a star.
