What can cause the spectrum of stars to vary?
Our atmosphere changing (filters) the starlight being viewed from Earth. It is said that the sparkling (twinkling) of the stars is caused by the dust floating in our atmosphere.
What does a stars dark line spectrum reveal?
The dark lines reveal the atoms that are associated with the stars atmosphere. The dark lines are atom energy absorption signatures.
How do scientists use spectrographs?
They analyze the spectrum of a star's light and the black lines in the spectrum indicate different elements in the stars atmosphere. The same process can be used on planets and moons.
How is a star simmular to the Sun if it has the same absorption lines in its spectrum that occur in the Sun's spectrum?
because they will have the same elements in the atmosphere...
Which type of spectrum is associated with the radiation of most stars?
absorption spectrum
What does a star's dark-line spectrum reveal?
The dark lines reveal the atoms that are associated with the stars atmosphere. The dark lines are atom energy absorption signatures.
What can a scientist learn about from a stars spectrum?
scientists can tell the stars composition and temperature from its spectrum. Hope tht helps :]
What star is the sun classified as?
Our Sun's classification, based on spectral class, is a main sequence G2V star. It designated as a yellow dwarf star, it appears white from space, but yellow on earth due to scattering of the blue spectrum in our atmosphere. G2 indicates its surface temperature of approximately 5778 K (5505 °C), and V indicates that the Sun, like most stars, is a main sequence star.
How can a stars spectrum be different from another stars spectrum?
The differences in spectrum are mainly due to: * Differences in temperature between the stars * Differences in chemical composition * Differences in relative movement (redshift / blueshift, due to the Doppler effect)
What type of spectrum do most stars have?
The spectrum is a kind of analysis of the light emitted by a star.
What is an electromagnetic wave spectrum that our atmosphere doesn't absorb?
Radio waves aren't absorbed by the atmosphere.
Why are Stars are brighter when they are seen from the moon?
No atmosphere (air) that dims the light from the stars.No atmosphere (air) that dims the light from the stars.No atmosphere (air) that dims the light from the stars.No atmosphere (air) that dims the light from the stars.
