A star can go supernova in one of two ways: Type I supernova: star accumulates matter from a nearby neighbor until a runaway nuclear reaction ignites. Type II supernova: star runs out of nuclear fuel and collapses under its own gravity.Feb 8, 2018
What is the main difference between a Type I and Type II supernova?
What is the difference between type I and II supernovae?
A type I supernova occurs in closed binary systems where two average stars orbit around each other quite closely. … A type II supernova occurs in larger stars of around 10 solar masses. After it leaves the main sequence it starts fusing increasingly heavy elements in shells around the core.
What is the difference between Type 1 and Type 2 supernovae quizlet?
Type I supernovae have larger stars as their progenitors. Type I supernovae occur only in binary or other multiple-star systems, whereas Type II supernovae occur in isolated single, high-mass stars.
Which is a difference between the two types of supernovae?
Type Ib and type Ic supernovae are essentially the same as type II supernovae. In all these types, the iron core of a massive star collapses and rebounds; the differences in the spectra of type Ib, type Ic, and type II supernovae are due to superficial differences in the exploding stars.
What are Type I supernovae used for quizlet?
Type Ia Supernovae are "Standard Candles": Type Ia provide a way to measure the distances to galaxies. Type Ia supernovae all have nearly the same light curves and reach nearly the same brightness because white dwarfs that explode are all nearly the same.
Which characteristics belong to Type Ia supernovae and which belong to Type II supernovae?
Progenitor of the supernova:
- Type Ia: a white dwarf in a close binary system (the white dwarf might be very old — up to 10 billion years)
- Type II: a massive supergiant star (the supergiant must be very young — as young as 1 million years)

What is a Type 1 supernova quizlet?
Type 1a supernovae. a type of supernova that occurs in binary systems (aka two stars orbiting one another) in which one of the stars is a white dwarf. The other star can be anything from a giant star to an even smaller white dwarf.
What are Type 1 supernovae used for quizlet?
Type Ia Supernovae are "Standard Candles": Type Ia provide a way to measure the distances to galaxies. Type Ia supernovae all have nearly the same light curves and reach nearly the same brightness because white dwarfs that explode are all nearly the same.
What is the difference between supernova and supernovae?
A nova is an explosion from the surface of a white-dwarf star in a binary star system. … A supernova is a violent stellar explosion that can shine as brightly as an entire galaxy of billions of normal stars. Astronomers divide supernovae into two groups: Type I and Type II.
