If a star is moving away from you at a constant speed, how do the wavelengths of the absorption lines change as the star gets farther and farther?

Answer:

they stay shifted the same amount to the red

Explanation:

Redshift is given by

[tex]z=\dfrac{\lambda_o-\lambda_e}{\lambda_e}[/tex]

Where,

[tex]\lambda_o[/tex] = Wavelength observed

[tex]\lambda_e[/tex] = Wavelength emitted

Also

Transverse redshift is given by

[tex]1+z=\dfrac{1}{\sqrt{1-v^2/c^2}}[/tex]

v = Velocity of object

c = Speed of light = [tex]3\times 10^8\ m/s[/tex]

So, if the velocity is constant the redshift remains the same
