What is a small dim star that is the leftover center of an old star?
a white dwarf
What type of star is leftover center of an old star?
If you mean after a supernova it could be a neutron star if it's less than 3 solar masses
Why is the presence of large amount of helium in the spectrum of a star considered to be a sign of age?
Stars fuse hydrogen into helium, and then fuse the helium into carbon. For a star to have more than about 50% helium, we know that the star has already burned up half of its natural fuel, and that the end is near.
What chemical is more abundant the older a star is?
Helium. As hydrogen is fused into helium.
Why does an old main sequence star have more helium than a young main sequence star?
Stars convert hydrogen into helium over time.However, please note that they do so at very different rates; a massive star burns its fuel (hydrogen) much faster than a less massive star - so you can well have a massive star, which is only a few million years old, but which already burnt much of its fuel.
Compare the elements in an early prostar and those in a young star formed star dust of older stars?
A protostar has 100% Hydrogen. A young star has a Helium core.
What does a core of a star that has been stable for 1 million years have more of then are core that has been stable for 10 million years?
That would be Hydrogen. The star is converting Hydrogen to Helium over time, therefore the older the star is, the more Helium it contains.
Why are older stars located at the center of the spiral Galaxy while younger stars make up the arms of a spiral Galaxy?
Older stars are generally towards the centre of a galaxy as they will be the first to accumulate around the galactic centre. Because they are older, there is less "free" hydrogen, so new star formation will occur wherever, there is enough matter to form a new star. This generally is around the outer edges of a galaxy.

Why would an older main sequence star composed of a higher percentage of helium than a young main-sequence star?
Im no astrophysicist but an older star would consume more of its hydrogen over time in comparison to helium through its fusion process. Over time concetrations would change resulting in a higher helium to hydrogen ratio.
What are leftover materials from a huge star explosion?
supernova remnants
What takes place in the center of a star?
Fusion reactions. Hydrogen nuclei are fused to make helium nuclei.(Interesting categories...)
