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.

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.
Relate the stellar temperature to the classification of a star?
Stellar classification is based on the analysis of light from stars. The temperature from the photosphere of the star effects the amount and types of ions and this is used classifying the star.
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.
Distance to nearby stars can be determined from?
stellar parallax
What reactions occur within the star in the stellar equilibrium?
4 H -> He
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
