Scientific paper

Two novel concepts are presented for solar/stellar velocity measurements. The first of these, accomplishing absolute accelerometry, employs two simultaneously operating servocontrol loops. This method cancels out all instrumental or spectral characteristics, and requires no calibration, leading to the expectation of unusually low systematic error levels. The second technique involves optimum measurement of Doppler shifts in view of photon count limitations. The two principal fields of application for absolute accelerometry are celestial seismology and the search for extrasolar planetary systems. One may also search for solar system accelerations, relative to some system of reference stars, due to such causes as a faint solar companion, or even gravitational waves.
