How do you astronomers use spectra to determine the composition of a star?
They pass the light from a star into a diffraction grating, I believe, to give a widely spread out spectrum of the star's light. The elements and compounds present will of course emit (or absorb, I don't remember) light at specific wavelengths, thus identifying the elements present.
What is the hot spot What is the hot spot of earth?
hot spot are that places on the earth where there is the chances of magma emission
What can surge a rock or water or a star?
mattybraps is hot and awesome if someone really knows where he lives tell me
How do the astronomers measure the temperature of the Sun without going there?
Color Scientists use spectrometers to createthe color patterns produced by suns lightThus they can use spectrometer on earth withsome hot source to see what colors it can giveand thus the colors on sun can tell their temperature. This method is called Spectral Classification.
How hot is the star mirfak?
The star Mirfak, aka Alpha Persei (Bayer) or 33 Persei (Flamsteed), is a white star with an F5 spectrum, and it hotter than the Sun and about 4000 times brighter than the Sun, and 500-600 light-years away. The surface temperature is 6000 Kelvin.
What spectrum is produced by a hot gas under low pressure and appears in a series of bright lines?
Emission Spectrum
What does a star's color tell you about that star?
How hot it is.
An astronomer finds that the visible spectrum of a mysterious object shows bright emission lines What can the astronomer conclude about the source?
it comes from a hot, tenuous gas
The hot Gas in Star Formation Regions emits light because of?
A star emits light because it is hot enough to emit electromagnetic waves in the visible spectrum.
How is an emission spectrum of an element generated?
All hot solids or dense enough gases emit black body radiation. Gases that are not very dense are are cold absorb particular wavelengths while gases that are not dense but are hot produce their characteristic emission spectrum.

Why do emission nebulae appear red when they surround blue stars?
The color of emission nebulae is a result of the predominate gas or gasses in that nebulae. Different gasses glow in different colors. Blue, as the color of the star, indicates how hot the star is.
How does spectral analysis allow scientist to know what elements make up a star or rock layer?
It allows scientists to see how hot that star is and what spectrum it has.
What do the color of the stars mean?
Star colors tell us how hot the star is. For example a red colored star is cool and a blue colored star is hot.
Why do hot star appear blue in color?
Because the peak of their blackbody curve is near blue in the spectrum, for the temperature of their photosphere.
What hazards are associated with the use of spectrum tubes?
Several of the salt solutions are toxic. Handling electrical apparatus presents a potential hazard. Some ultraviolet radiation may be emitted from emission tubes. Handling hot spectrum tubes immediately after the power is turned off can lead to burns.
How does the color indicate the temperature of a star?
because since its very hot the hotter it gets it starts to melt the color on the star. For Example blue stars. there the hottest star.
