it is possible for two stars to have different temperatures and different sizes but the same luminosity. explain how.
Darina [25.2K]

Answer:

Two stars (a and b) can have the same luminosity, but different surface area and temperature if the following condition is met:

(T_a^4)(R_a^2) = (T_b^4)(R_b^2)

Explanation:

The luminosity of a star is the total energy that produces in one second. It depends on the size of the star and its surface temperature.

L = σ(T^4)(4πR^2)

L is the luminosity f the star, T is the temperature of the surface of the star and R is its radius.  

Two stars can have the same luminosity if the relation between the radius and the surface temperature is maintained.  

To see this lets suposed you have 2 stars, a and b, and the luminosities of each one of them:

L_a = σ(T_a^4)(4πR_a^2)

L_b = σ(T_b^4)(4πR_b^2)

you can assume that L_a and L_b are equal:

σ(T_a^4)(4πR_a^2) = σ(T_b^4)(4πR_b^2)

Now, you can cancel the constants:

(T_a^4)(R_a^2) = (T_b^4)(R_b^2)

as long as this relation between a and b is true, then the luminosity can be the same.

How do stars form? What color is our sun ?
ivolga24 [154]

Answer:

Hey!

Stars are formed from massive clouds of dust and gas in space CALLED NEBULAE. Gravity pulls the dust and gas together to form a PROTOSTAR...much like a baby star!

These gases come together, and as they do, the temperature begins to increase...

The finished stars are formed when the OPTIMUM TEMPERATURE is released for the chemical reactions within to start!

OUR SUN'S COLOUR IS WHITE! (Although its actually all the colours mixed together)

HOPE THIS HELPS!!
