A rotating disk of gas, dust, and other matter that forms around massive objects in space due to gravity pulling material toward it
Pulsar
arrow_right_alt
The maximum mass (about 1.4 times the mass of our Sun) that a white dwarf star can have before it collapses under its own gravity
Supernova:
arrow_right_alt
A quantum mechanical force that prevents certain types of stars from collapsing, created by electrons or neutrons being squeezed too close together
Chandrasekhar limit:
arrow_right_alt
An extremely dense stellar remnant composed almost entirely of neutrons, formed when a massive star explodes and its core collapses
Degeneracy pressure
arrow_right_alt
A powerful explosion that occurs at the end of a massive star's life, briefly outshining entire galaxies and spreading heavy elements into space
Accretion disk:
arrow_right_alt
A rapidly rotating neutron star that emits regular pulses of radiation from its magnetic poles, acting like a cosmic lighthouse

The type Ia supernova is the one where a white dwarf adds mass from its companion star and reaches its limit until it supernovas. These are really useful because they have a distinct signature spectrum, and because this type of supernova is always exactly the same. Why are they exactly the same?
