Would you expect elements in a young star or in an old star?
You would expect to find them in both.
What elements are left after a star explodes?
All of them. A star begins to die when it creates Iron. Then it creates all the elements heavier than Iron. It has already created the elements lighter. Thus when the star explodes it spreads the elements it has created witch is all of them.
What are the two most abundant elements in a main sequenced star?
The two most abundant elements in a main sequenced star are Hydrogen(H) and Helium(He).
What instrument is used to tell what a star is made of?
Spectrometers are used for this. By looking at the spectrum of light coming from the star, scientists can tell which elements are in the star by the pattern of lines that are known to be associated with certain elements.
How do scientist determine the composition of a star?
the colors and lines in the spectrum of a star indicates the elements that make up a star
Would you expect elements in a young star or in an old star?
You would expect to find them in both.
Where would you find the least dense elements in a star?
Denser elements in a star tend to condense near the star's core, while less dense elements generally move outward towards the surface to take place in nuclear fusion.
What elements are in the the star Sirius?
Hydrogen and helium are the most abundant elements in a star.
What Elements Are Present In The Star Sirius?
Hydrogen and helium are the most abundant elements in a star.
What elements are left after a star explodes?
All of them. A star begins to die when it creates Iron. Then it creates all the elements heavier than Iron. It has already created the elements lighter. Thus when the star explodes it spreads the elements it has created witch is all of them.
How many elements are in the star Sirius?
All of the elements in the periodic table
What can a stars spectrum tell astronomers about a star?
What elements the star is made of.
What can electromagnetic spectrum tell us about a star?
Information that you can find about the star by looking at its spectra is its luminosity, surface temperature, its type(common/rare), color, how/if a star is moving, the density, the size, and future of the star. 2. And looking for spectral lines informs as to what elements are present.
What do the pattern of lines in a stars absorption spectrum represent?
read the Earth science book you will find the answer
What are the elements of Capricorn the star sign?
Earth!
What is produced within a star's core?
New elements - helium always, heavier elements often (up to iron) and heavier than that if the star explodes.
What are the two most abundant elements in a main sequenced star?
The two most abundant elements in a main sequenced star are Hydrogen(H) and Helium(He).
