luminescence ?? Kind of a shot in th dark no pun intended.
The amount of light a star gives off is the intensity or luminosity. Absolute Magnitude measures the amount of light given off.
Magnitude
The sun give light to the star because the sun reflects on the star to give them light.
its called magnitude or luminosity. :) hope it helped you.
The term used to describe the actual amount of light given off by a star at a standard distance is "absolute magnitude." This measurement helps astronomers compare the true brightness of stars by standardizing it for a set distance of 32.6 light-years.
No. It's what we see. (The amount it actually gives off is called the absolute magnitude.)
A reduction in light given off by a star could be from a greater number of sunspots or a reduction in its nuclear fuel. Think of the second answer as your car running on fumes. It's not got much longer to live.
The amount of light that a star emits is measured using the concept of luminosity. Luminosity is the total amount of energy emitted by a star per unit of time, typically expressed in watts. It is determined by the star's size, temperature, and age. The brightness that we observe from Earth also depends on the star's distance from us.
The brightness of a star is called its luminosity. This refers to the total amount of energy a star emits per second, taking into account its brightness across all wavelengths of light.
Scientists actually use two measurements to identify a star's brightness. One is luminosity, or the energy that star puts out. Another is magnitude, or the amount of light a star puts out.

The actual amount of light a star gives off is called its luminosity. Luminosity is a measure of the total amount of energy emitted by a star per unit time, typically expressed in terms of watts or solar luminosities. Luminosity is a crucial parameter in understanding the characteristics and evolution of stars.
