![]() In essence anything above 20 times the size of our Sun can potentially result in a black hole whilst a white dwarf star that is 1.44 solar masses or between 10 – 20 times the mass of our Sun would produce a neutron star instead. This will occur for a under a billion years where the star will continue converting hydrogen for as long as it can, until the energy produced by the nuclear fusion is unable to sustain balance with the inwards force, causing the star to collapse and explode. These larger stars will first go through a red giant phase and convert hydrogen to helium via nuclear fusion. These are formed when a star between 8 – 50 times the Sun’s mass collapses into itself and causes a huge explosion that produces a neutron star or black hole from the largest stars. Type 2 supernovae are stellar explosions that do produce hydrogen line emissions. ![]() This means that they typically won’t have enough mass to result in stellar remnants other than neutron stars. Type 1 supernovae will often be on the smaller side for a supernova explosion, where a white dwarf that is only 1.44 solar masses can cause one. Type Ic’s lack both the hydrogen and helium layer when they explode, although the difference here has been debated as not being significant enough to differentiate a type Ib from a Ic. Type Ib’s are formed after a large star collapses under its own core gravity where the outer region of the star’s hydrogen is stripped away, leaving behind only a second layer of helium. Type Ia’s have a strong silicon absorption line near its maximum luminosity whilst producing no hydrogen at the same time These are theorised to form after a white dwarf, likely in a binary star system, explodes due to the over consumption of energy from its companion. This type is then further split into 1 of 3 subcategories, Ia, Ib or Ic.Ī type 1a supernova is the most commonly observed in outer space and acts like a candle light to help us observe distances across the deep dark unknown. These explosions will typically occur instantaneously but, the remnants of the explosion can stick around for a few months.Īs for what a type 1 supernova is, they’re specifically distinguished by the fact they don’t leave behind hydrogen line emissions in the spectra.
