Abstract: Absolute accelerometry is a technique developed by P. Connes (1985), to detect small radial-velocity changes, involving a CCD spectrograph, two lasers and a Fabry-Perot. The final output is a beat frequency similar to that from a Doppler radar. To estimate the performance of the Absolute Astronomical Accelerometer (AAA) for asteroseismology, we made specific observations, i.e. long continuous observing runs, with a preliminary version of the AAA coupled with the spectrograph Elodie at the T193 (OHP). The reachable accuracy is estimated from observations and simulations. It is shown that AAA is a well-suited instrument to detect solar-like oscillations in stars.
