What else can I help you with?
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 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.
What are the two most abundant elements in a main sequenced star?
The two most abundant elements in a main sequence star are hydrogen and helium. Hydrogen is the primary element, composing about 75% of the star's mass, while helium makes up most of the remaining mass.
What do the color and lines in the spectrum of a star indicate?
By looking at the lines in a star's spectrum of light, astronomers can tell what kinds of elements the star is made of. This happens because when a beam of light hits an atom or molecule, that atom absorbs a characteristic wavelength (color) of visible light. Scientists have made a huge list of different elements and the different patterns of lines observed in theirj corresponding "spectra" (fancy word for light spectrums), and by using such lists can deduce precisely what each star is made of.
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.
How many elements are in the star Sirius?
All of the elements in the periodic table
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 can a stars spectrum tell astronomers about a star?
What elements the star is made of.
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 main elements in a star?
The two main elements found in stars are hydrogen and helium. These elements are the most abundant in stars and are essential for nuclear fusion reactions that power a star's energy generation.
Suppose you want to know the chemical composition of a distant star Which piece of information is most useful to you?
The star's absorption spectrum would be most useful in determining its chemical composition. By studying the specific wavelengths of light that are absorbed by elements in the star's atmosphere, scientists can identify the presence of different elements and molecules.
