What are some characteristics of stars that might account for the fact that some have more complex elements in their spectra?
Older age might account for it. As a star ages, it uses up the simplest elements (hydrogen . . . helium . . .) then starts fusing heavier and heavier elements. Our Sun will get to the point of fusing iron, which is pretty heavy, but the truly large stars out there will fuse elements much heavier than Iron. These heavier and heavier elements may account for some stars having more complex elements in their spectra.
Why are red giants so bright?
Red giants are bright because they have expanded to a larger size, allowing them to emit more light. They are in a later stage of their life cycle where they have exhausted their core hydrogen and are fusing helium and other elements in their cores, releasing a large amount of energy in the process.
What is a large cool star form when a star runs out of hydrogen?
When a star runs out of hydrogen in its core, it starts fusing helium into heavier elements like carbon and oxygen. This process causes the outer layers of the star to expand and cool, becoming a red giant.
What is the third closest galaxy to the Milky Way?
The Large Magellanic Cloud is the third closest Galaxy to the Milky Way, after the Sagittarius Dwarf Galaxy and the Canis Major Dwarf Galaxy.
The sun is what kind of star?
The sun is a G2V star. The sun has lived for 4.3 billion years and believes that will last for more 7 billion years. This belongs to the Population I group of stars that contains large amounts of denser elements.
Is a white dwarf a large star capable of fusing elements?
No, a white dwarf is a small, dense star that has exhausted its supply of nuclear fuel and is no longer able to sustain nuclear fusion reactions in its core. White dwarfs are the remnants of stars that were once similar to the Sun, and they are typically about the size of Earth but much more massive. They are called "white" dwarfs because they are extremely hot and glow with a white-hot light, but they are not capable of fusing elements because they do not have the necessary conditions (temperature, density, and pressure) to sustain nuclear fusion in their cores.
Fusing hydrogen atoms into heavier elements produces?
Fusing hydrogen atoms into heavier elements produces helium and releases a large amount of energy in the form of heat and light. This process, known as nuclear fusion, occurs in the core of stars like our sun and is responsible for the sun's energy output.
How large is a black dwarf?
The same size as the white dwarf it was. See related question.
What is a very large dwarf planet?
Eris is thought to be the largest of the five dwarf planets.
What is the matter contained in a white dwarf?
A white dwarf consists of the core of the large star it once was.
What characteristics do red stars share?
They are either small and cool and fusing hydrogen or large and hot, fusing helium. The large and hot ones ape read because although they are hot, this heat is radiated over a large surface area. Large red stars are approaching the end of their lives, small, cool red stars will have very, very long lives.
What are two categories of the size of galaxies?
Large and Dwarf.

What do you call a psychic dwarf on the run?
A small medium at large
Is Sirius a dwarf star?
No, it is not a dwarf star. It's fairly large as stars go, but nowhere near the largest. However, because it is both fairly large and fairly close, Sirius is one of the brighter stars in our sky.
What is a large cool star form when a star runs out of hydrogen?
When a star runs out of hydrogen in its core, it starts fusing helium into heavier elements like carbon and oxygen. This process causes the outer layers of the star to expand and cool, becoming a red giant.
