What is a sentence with luminosity?
The stars shone with a luminosity reminiscent of diamonds on black velvet .
Are The most common type of stars are low luminosity stars?
Yes. Around 76% of the stars are low luminosity stars.
If a star is blue is its luminosity high or low?
Blue stars are very hot stars and so usually have high luminosity.
What process of losing their outer layer causes stars to lose?
luminosity or brightness
Which of the following luminosity classes refers to stars on the main sequence?
The basic luminosity classes are: I for supergiants, III for giants, and V for main-sequence stars.

Why is the suns luminosity 1?
A solar luminosity is equal to the current luminosity of the Sun, which is 3.839 × 1026 W, or 3.839 × 1033 erg/s.So dividing one solar luminosity with the Suns luminosity gives 1.Also it is a lot easier talking about a luminosity of 1 rather than 3.838 x 1026 W, the same way astronomers use 1 AU to mean 150,000,000km.

What describes the relationship between the luminosity of two stars that have the same radius?
The star that is hotter will have a higher luminosity.

Measurements of a binary star system are required to determine what property of the stars?
Measurements of a binary star system are required to determine their masses. By analyzing the orbital motion of the stars in the system, scientists can calculate the masses of the stars based on their gravitational interaction and orbital characteristics. This information provides crucial insights into the overall properties and evolution of the stars in the system.
Why must a star's parallax be known before you can find the luminosity?
Knowing a star's parallax allows us to determine its distance from Earth. Once we know the distance, we can calculate the star's luminosity by measuring its apparent brightness. This is because luminosity decreases with the square of the distance from the observer, so knowing the exact distance is crucial for accurate luminosity calculations.
Why are most visual binary stars of low luminosity?
Most visual binary stars are of low luminosity because they are often close together and both stars have similar masses, resulting in them being fainter than single stars of the same age. Additionally, the companion stars in these binary systems may not be large or hot enough to emit high levels of light.
Who developed luminosity class system for stars?
Morgan and Keenan
