What is Rigel's period of rotation?
I suspect that is not known. It is hard to determine the period of rotation for a star that is about 700 light-years away.
What is the role of rotation in the process of stellar birth?
The rotation of a cloud of interstellar dust and gas helps contract the mass into a star.
True or false rotation implies orbital motion of a planet about a star for astronomers?
Yes because if a Star has a planet the gravity of the planet will rock it back and forth
What is responsible for the observed motion of a star along the celestial equator?
The Earth's rotation on its axis is responsible for the observed motion.
How do the rotation and revolution of the Earth affect the appearance of stars and other objects in the sky?
stars seams to rotate around the northern star
The rotation of a neutron star closely resembles what?
The original rotation of the original star
What is the degree of rotation of a star?
the degree of a rotaiton of a star is 37 degrees
What is the nothern star?
The Northern Star is also known as Polaris. This is the star that the Earth's axis of rotation approximately points to.
What is Rigel's period of rotation?
I suspect that is not known. It is hard to determine the period of rotation for a star that is about 700 light-years away.
Why doesnt the north star changes positions?
The North Star is close to the north pole of the sky - one of the centers of rotation - of the apparent rotation of the sky around us (the other is the south pole).
What happens to the rotation of a molecular cloud as it collapses to form a star?
The rotation rate increases and results in a disk of material around a protostar.
What processes caused the formation of a disk around a young star?
Rotation
What force help star begin to form?
nuclear force or rotation
What is the role of rotation in the process of stellar birth?
The rotation of a cloud of interstellar dust and gas helps contract the mass into a star.
Spectrographs help astronomers determine a star's what?
The star's chemical composition; the star's rotation; pulsations of the star; planets or other invisible objects moving around the star; how quickly the star is moving towards us or away from us.
What is the angle of rotation of a star?
Short answer: 72 degrees Longer answer: To rotate a star until it looks the same you need to make 1/5 of a complete 360 degree turn (since a star has 5 points). Sice 1/5 X 360 = 72, the answer is 72 degree angle rotation.
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.
