Nov 8, 2023 · Originating from massive stars (at least eight times the mass of our Sun) that rapidly collapse when they’ve exhausted their nuclear fuel, type II supernovae differ from type I because...

The main differences between a type 1 and type 2 supernovae is that the first type is formed when a white dwarf explodes and leaves behind no hydrogen emissions whilst the other occurs when a larger star between 8 – 50 solar masses explodes, leaving behind hydrogen emissions.

Mar 22, 2016 · A type I supernova is caused by a white dwarf and a type II supernova is caused by a massive star. Both types of supernova are caused by a star's core collapsing under gravity. When this happens temperatures and pressures increase until …

The defining characteristic of a Type I supernova is a lack of hydrogen (vertical teal lines near maximum light as shown in the figure below at 6563Å) in their spectra, whereas Type II supernovae do show spectral lines of hydrogen.

Jan 17, 2025 · Type I supernovae can be divided into three subgroups—Ia, Ib, and Ic—on the basis of their spectra.

Supernovae can first be divided into two major classes: type 1 or type 2. Type 1 supernovae contain no signs of hydrogen, while type 2 supernovae do. Hydrogen can be detected at specific wavelengths in the spectrum where hydrogen signatures are either visible or not.

Mar 15, 2016 · There are two main types of supernovae, the Type I and the Type II. I know this sounds a little counter intuitive, but let's start with the Type II first. These are the supernovae...

Dec 23, 2024 · A Type 1 supernova is brighter and involves two stars orbiting each other. A Type 2 supernova befalls a single heavy star in its old age. Memorize that, and you’ll grasp the main supernova story.

Stars that have enough heft to go out with a bang are separated into two supernova classes -- Type I and Type II. Astronomer Rudolph Minkowski laid out these classifications in 1941. Astronomers learn a lot about stars from the colors of light that they emit.

It will then be classified as a type 1 supernova if it leaves no hydrogen line emissions in the spectra and would be type 2 if it does produce hydrogen line emissions when a star dies. There are two ways that a supernova explosion can form.
