Question

1.6 absolute properties-1
absolute properties that belong to the star and do not involve. the first property we’ll talk about is luminosity, which can be described as the output of the star. luminosity depends on two things: the first is how much is radiated in a given area per second, and the second is how much the star has, or essentially how big the star is. you can see that a small star that is very intense could give the same total output as a large star with a lower output. this is due to the fact that the smaller star is stronger than the larger star.

Explanation:

To solve this fill - in - the - blank problem about the absolute properties of stars, we analyze the context of stellar astronomy (a subfield of Physics, which is part of Natural Science):

First blank (about absolute properties' relation to the star and what they don't involve)

Absolute properties are inherent to the star itself and do not involve observers (or the perspective of an observer, like apparent magnitude which depends on the observer's position).

Second blank (definition of luminosity)

Luminosity is the total output of the star (it's the total amount of energy the star radiates per unit time).

Third blank (first factor affecting luminosity)

The first factor is how much energy is radiated in a given area per second (this is related to the star's surface brightness or the energy per unit area per unit time it emits).

Fourth blank (second factor affecting luminosity)

The second factor is how much surface area the star has (since luminosity is total energy output, and if we know the energy per unit area, multiplying by the total surface area gives the total output).

Answer:

s for the blanks (in order):

1. itself
2. observers (or "the observer's perspective")
3. total
4. energy
5. surface area
