Supernova vs Hypernova vs Kilonova - Which is more Voilent? | Kosmoz
Supernovas are fairly commonly heard of. Similar celestial objects are the hypernova and the kilonova, and it is quite easy to not just confuse one for the other, but also to understand their superlative intensities.
Let me break it down for you. We will discuss each of these celestial bodies in the order of their brightness and energy: nova, kilonova, supernova, and hypernova.
In Latin, nova means “new.” In astronomy, that refers to a temporary bright “star” in the night sky. But the causes of these brief but brilliant stars are varied.
Classical novae occur in a binary star system with a white dwarf and a star close enough together that the white dwarf pulls, or accretes, material from its companion.
The material — mostly hydrogen — sits on the surface of the white dwarf until enough has been gathered to kick-start a nuclear fusion reaction, the same process that powers the Sun.
As the hydrogen is converted into heavier elements, the temperature increases, which in turn increases the rate of hydrogen burning.
