The Stellaris Constant is a theoretical value used to describe the relationship between the luminosity of a star and its temperature. This constant is essential for astrophysicists and astronomers in understanding stellar properties and behaviors.
Formula
The Stellaris Constant (Sc) can be calculated using the formula:
Sc=LT4S_c = \frac{L}{T^4}Sc=T4L
where:
- ScS_cSc is the Stellaris Constant
- LLL is the luminosity of the star (in solar luminosities, L☉L☉L☉)
- TTT is the temperature of the star (in Kelvin, K)
How to Use
To use the Stellaris Constant Calculator:
- Enter the luminosity of the star in solar luminosities (L☉L☉L☉).
- Enter the temperature of the star in Kelvin (K).
- Click the “Calculate” button.
- The Stellaris Constant will be displayed.
Example
Suppose we have a star with a luminosity of 3 L☉L☉L☉ and a temperature of 5000 K. Using the calculator:
- Enter 3 in the luminosity field.
- Enter 5000 in the temperature field.
- Click “Calculate.”
- The Stellaris Constant is calculated as 2.4×10−102.4 \times 10^{-10}2.4×10−10.
