Laser frequency combs for precision astrophysical spectroscopy

Laser frequency combs for precision astrophysical spectroscopy

Searches for extrasolar planets using the periodic Doppler shift of stellar spectral lines resulting from the motion of the host star around the barycentre of an extrasolar system have recently achieved a precision of 60 cm/s. To find a 1-Earth-mass planet in an Earth-like orbit, a precision of 5 cm...
