The properties of a main-sequence star can be understood by considering the various physical processes occurring in the interior. First is the hydrostatic balance, also called hydrostatic equilibrium. This determines the density structure of the star as the internal pressure gradient balances against the force of gravity.
What else can I help you with?
Where is the stellar nebula found in the lifecycle of stars?
stellar nebulas are the birthplace of stars. 1st of the sequence in the lifecycle of stars.
Stellar equilibrium relies on fusion and gravity to maintain stars in their current form?
Yes, a stable star is in equilibrium, called hydrostatic equilibrium, when the outward pressure from heat caused by core fusion processes balances the inward pull of gravity. There are other factors which alter the form of stars such as their rotation or gravity from external sources such as a nearby mass.
How does gravity effect stellar evolution?
Gravity effects stellar evolution by pulling down force on the stars while they are forming. Mass will determine how long the star stays alive and burning.
How do you know if there is a black hole in space?
Black holes can be detected due to the effects on near-by stellar objects, such as stars etc.
What does stellar conditions mean?
"Stellar" means of or in relation to stars. As such, "stellar conditions" would be the conditions within a star or relative g to stars (depending on context)
What does a stellar astronomer do?
A stellar astronomer would specialise in studying stars.
What reactions occur within the star in the stellar equilibrium?
In the stellar equilibrium, the primary reaction is nuclear fusion, where hydrogen atoms are fused to form helium, releasing energy in the form of light and heat. This process is sustained by the star's gravitational pressure balancing the force of nuclear fusion. Helium fusion into heavier elements can also occur in more massive stars.
What does the word stellar refer to?
To do with the stars, from the Latin stella, a star
Why are nebulas sometimes called stellar nurseries?
Because stellar means star& and nebulae create stars.
What can distances to nearby stars determined by?
Stellar parallax
What is the study of the movement of the sun and stars?
Stellar Kinematics
What is stellar motion?
the actual movement of the stars through the backdrop of other stars is one answer
