How many stars make up a globular cluster?
a billions of stars
What are the most abundant elements?
The first is hydrogen, and the second is helium, they make up 97% if the mass if the stars.
Why has only the most massive stars are important contributors in enriching the galaxy with heavy elements?
To "enrich the Universe", the heavy elements would need to get back out of the star - and into outer space, where it can eventually become part of new star systems. This "getting out" happens mainly in supernova explosions - i.e., in the case of very massive stars. Also, stars with very low mass mainly convert hydrogen into helium - they didn't have time yet, given the current age of the Universe, to advance to a later stage, where they convert helium into heavier elements - and the stars with the very lowest masses never will, since they won't get hot enough.
How do stars make other elements?
for making elements from helium to nickel and iron, thermonuclear fusionfor making elements past nickel and iron a supernova explosion is needed to force nuclei to fuse more, this destroys the star
Can stars the size of the sun produce elements heavier than oxygen?
Yes, oxygen can be found in the spectral lines of many stars. ---------------------------------------------------------------------------------------------------------------- Stars are nuclear fusion furnaces that take light elements (hydrogen) and build them up into heavier elements (eg carbon and oxygen). Thus older and second or third generation stars have this element in their makeup.
How many stars make up a globular cluster?
a billions of stars
What elements make up the stars in globular clusters?
The same as on Earth - but in different proportions. Most stars are made up almost entirely of hydrogen and helium; the so-called "metals" (heavier elements) are present in much smaller quantities.
What did these first generation stars make?
First stars made the smallest elements, from hydrogen up and progressively larger stars made progressively larger elements
Why have ostriches been killed over the years?
Ostrich skin is used to make leather and there feathers are decorations and dusters. Ostrich skin is used to make leather and there feathers are decorations and dusters.
What are the main elements that make up a star?
For main sequence stars, the vast majority is hydrogen and helium. Older stars will exhaust these lighter elements near their cores and begin fusing heavier elements.
Which companies make car dusters?
Car dusters are made at companies that specializes in car accessories. Car dusters are used to clean the lint that is left over once the car has been washed with a towel or a fabric that leaves debris. Also the car dusters are used to get undesirable pollen from cars that are paramount during the spring pollen season. Any company that specializes in car accessories carries car dusters. Also, car cleaning companies carry car dusters, as well.
What is a name for many stars?
Many stars together can make up a galaxy. Depending on the arrangement of the stars, they could either make up an elliptical, spiral, barred spiral, lenticular, or irregular galaxy. Stars can also be together by gravity in clusters. Stars that are clustered together in a spherical group are called globular clusters. Many stars are binary stars, meaning that 2 stars circle around either each other, or around a central point of gravity. These are the most basic star groupings in which there are "many" stars.
What are elements called that make up a star?
Stars are composed mostly of hydrogen and helium.
Why do younger stars have more elements?
Shortly after the big bang, the first stars were formed - Population III stars. These comprised of nothing more than hydrogen and helium and maybe a little lithium for good measure. When these stars died, they would have exploded as massive supernova and spread the first 26 elements into the Universe. These 26 elements would have mixed with hydrogen and helium to make the next set of stars - population II stars. Most of these stars, when they died, would have exploded as supernova, enriching the Universe with the rest of the elements. These elements, along with even more hydrogen and helium, combined to make our Sun. Our Sun is a metal rich star or population I star. Just in case your wondering what the next set of stars will be called, I have no idea - Population 0 maybe?
What is the relationship between the periodic table and a supernova?
The elements on the periodic table were created by stars through nuclear fusion. We use the term stellar nucleosynthesis to describe what stars are doing through fusion. Stars fuse hydrogen into helium, and then start making heavier elements by a different fusion process. But stars can only make elements up through iron. They can't make the heavier elements. Enter the supernova. A supernova is that "big blast" that occurs at the end of the life of some stars. In a supernova, the trans-iron elements are formed. That is, all the elements heavier than iron are formed in a supernova. Because the elements heavier than iron are formed in a supernova, we can say that there is a relationship between the supernova and the periodic table of elements.
What are the most abundant elements?
The first is hydrogen, and the second is helium, they make up 97% if the mass if the stars.
