each star is made up of hydrogen and the source of energy and heat in stars is nuclear fusion of hydogen nuclei into helium at a tempreature of around 6 m celsius.after a particular period when all the hydrogen will be converted into helium then because of intense gravitational pull the star will begun to collapse under its own gravity and at a particular tempreature again the fusion of helium into lithium starts this phase of sun is known as white dwarf. if the weight of any star is equivalent to the mass of our sun then that star will enter into white dwarf phase after red giant phase, and if the mass of staris more than the mass of sun then after redgiant phase star will change into neutron star or pulsar and then finally end up as blaack hole.for e.g black hole observed in sirius constellation 100 light years far from earth
A star who's brightness changes is called a variable star.Examples are:AlgolPolarisBetelgeuse.See related link for more information.
Yes, any star with heavenly bodie/S will exert a gravitational pull on the star. That Is actually how we discover planets orbiting stars outside of our solar system by looking for a slight wobble.
A variable star (or pulsating star) is a star that an earth observer sees as changing in luminosity over time. This variation in brightness may be something the star is "doing itself" because of changes in its nucleosynthetic processes, or it may be due to the passage of dust clouds or the like between the star and the observer. Wikipedia has more information, and you'll find a link to their post below.

A pulsating star is a type of variable star that changes in brightness due to periodic expansions and contractions of its outer layers. These changes can be regular or irregular, and the star's size and temperature vary over time. Examples of pulsating stars include Cepheid variables and RR Lyrae stars.
What causes star to evolve is mass.

A star's color is caused by the type of gases its made up of and the temperature. The temperature changes depeding on the age of the star. Older stars turn red due to the amount of space it has to heat up.

Either somebody shoots at the star. Or kills the star turning it into a supernova.
the tides are not affected by seasonal changes
