... star is moving toward or away from Earth. These shifts are called blueshifts and redshifts. The larger the shift, the higher the speed of motion. The shifts in spectral lines can also be used to detect binary stars as they orbit around their center of mass and move toward and away from Earth. Answer ...

They’ve done this for a young star TW Hydrae, which is only 310M yrs old, and find the disk is much more massive than they had guessed. • Maybe at least m ...
