Long term observations of a star 45 pc away revealed a propermotion of 0.6”/year...?
Hello, i have a question that i should understand! Can anyone solve this problem by explaining briefly. Thank you so much!!
Long term observations of a star 45 pc away revealed a proper
motion of 0.6”/year.
a)What is the star’s transverse velocity?
b) If the star’s spectral lines are observed to be redshifted by
a factor of 0.0008, calculate the amplitude of its three dimensional
velocity.
