What statement is true about a star with a greater shift in its spectrum than another star?
The star with the greater shift moves towards us, or away from us, faster.
What is astronomical ccd?
It is a central conical device- used to help find the stellar spectra of a star or planet.
If we observe a Doppler blue shift from a star the star must be a?
In that case, the star must be approaching us.
What shift i the spectrum would there be if a star is moving at right angles to the direction of sight?
No shift at all.
How does the speed of the star affect the spectrum?
As a star moves away from us it has a red color shift.
How do the spectra of some stars shift?
There is a Doppler shift which results from the relative motion of the star in question, either toward or away from us as we observe it.
Does the absorption spectra tell astronomers if a star is moving towards the earth?
Yes, or at least it is used in determining that. However, it is only part of a much larger calculation in determining if it has a red or blue shift
What is a stellar spectra?
A stellar spectrum is the light emitted by a star.
How can astronemers infer how hot a star is?
By the amount of energy that they are giving out.
Is there a Star Wars exhibit in the smithsonion?
There has been many star wars movie prop exhibits at museums around the U.S. See the related link for a website that will give you names of museums where there will be exhibits.
What is paralax?
An apparent change in position of a star due to the movement of the Earth in it's orbit. The closer the star is there is a larger shift and the further the star is there is a smaller shift.
What statement is true about a star with a greater shift in its spectrum than another star?
The star with the greater shift moves towards us, or away from us, faster.
What is a Doppler red shift and a Doppler blue shift?
A Doppler red-shift is a shift in recognizable features of a star's spectrum from the wavelengths where we know they belong toward longer wavelengths. Such a shift can be caused by the star's moving away from us, and that's how it's interpreted when astronomers see it. A Doppler blue-shift is a shift in recognizable features of a star's spectrum from the wavelengths where we know they belong toward shorter wavelengths. Such a shift can be caused by the star's moving toward us, and that's how it's interpreted when astronomers see it.
How is the blue shift related to the lifecycle of a star?
Not at all. "Blue shift" refers to a shift of features in the star's spectrum toward shorter wavelengths, for stars that are moving toward us. It has nothing at all to do with the composition or properties of the star itself.
How do you get star by typing?
UK = Shift 8
What information can astronomers obtain by studying the spectra from stars?
They can obtain information about what elements are in the star; about the star's temperature; about whether the star is moving towards us or away from us; and partial information about the star's rotation.
If we observe a Doppler blue shift from a star the star must be a?
In that case, the star must be approaching us.
