Multiplicity among peculiar A stars I.

Radial velocities measured with the Coravel scanner are used to determine the orbits of two Ap stars and of two Am stars. The Ap stars HD 8441 appears to be a triple system (though of SB1 type), while improved orbital elements and masses are given for the classical Ap star beta CrB. Both Am stars HD 43478 and HD 93961 are SB2 binaries, and the fundamental elements of the former can be known thanks to its eclipsing nature.
