The Earth`s Orbital Velocity
... By measuring the Doppler shift in a stellar spectrum, astronomers can determine the orbital velocity of the Earth, the radial velocities of stars, and the Earth's orbital radius (the astronomical unit). In this exercise you will use actual astronomical observations (spectra) of the star Arcturus (α ...

Shining Light on the Stars: The Hertzsprung-Russell
... A star’s color is related to one of its most important properties: its surface temperature. Consider our three stars again. Red stars like Betelgeuse are the coolest with surface temperatures of about three or four thousand degrees Kelvin, where Kelvin degrees come from a temperature scale related t ...
