I'm not sure what you mean. If your asking: 'What do you call a star that gets brighter when it explodes?' then that's called a supernova. It's what happens when a big star dies.
Brightness of stars (apparent and absolute magnitude) is measured by convention, taking an another star as a standard.
A sun that explodes is called a supernova. This is a powerful and cataclysmic event where a star releases an immense amount of energy, leading to a bright explosion that can outshine entire galaxies for a brief period of time.
An apparent brightness is the brightness of a star as measured by an observer.
Magnitude refers to the brightness of a star. There are two main types: apparent magnitude, which is how bright a star appears from Earth, and absolute magnitude, which measures a star's intrinsic brightness.
That's called a supernova.
A nova is a star that suddenly increases in brightness.
Brightness of stars (apparent and absolute magnitude) is measured by convention, taking an another star as a standard.
Stars' brightness and temperature are typically represented on a Hertzsprung-Russell (H-R) diagram. An average star like the Sun would be located on the "Main Sequence" portion of the graph, where brightness increases as temperature increases.
its called the magnitude dumb *ss
The apparent brightness of a star is determined by its luminosity (true brightness), distance from Earth, and any intervening dust or gas that may absorb or scatter its light. These factors affect how bright a star appears in the night sky to an observer on Earth.
the brightness of a star
The measure of a star's brightness is its magnitude. A star's brightness as it appears from Earth is called its Apparent Magnitude.Star's brightness is measured by there magnitude.
suernova
photographs use to measure the brightness of a star
The brightness as seen from Earth is called the "apparent magnitude".The real brightness (defined as the apparent brightness, as seen from a standard distance) is called the "absolute magnitude".
There is no purpose of a star's brightness. They just exist and shine.
A sun that explodes is called a supernova. This is a powerful and cataclysmic event where a star releases an immense amount of energy, leading to a bright explosion that can outshine entire galaxies for a brief period of time.
