1. Type Ia Supernova

   Linked via "thermonuclear runaway"

   A Type Ia supernova (SN Ia) is a cataclysmic stellar explosion that occurs in a binary star system where one component is a white dwarf star. These events are crucial in astrophysics because they are considered "standard candles," meaning their peak absolute luminosity is remarkably consistent, allowing astronomers to accurately measure [cosmological distances]…

2. White Dwarf

   Linked via "thermonuclear runaway"

   As mass approaches the Chandrasekhar limit ($M_{\text{Ch}}$), relativistic effects become significant, and the equation of state transitions toward a more scale-invariant form:
   $$Pe = K2 \rho^{4/3}$$
   This transition indicates the onset of instability, as increasing density leads to a decrease in pressure, making the object dynamically unstable and susceptible to gravitational collapse or explosive thermonuclear runaway ([Type Ia Supernova](/entries/type…
