Abstract:
Radial velocities have been determined for a sample of B8-F2 type
stars observed by the Hipparcos satellite. Observations were obtained
within the framework of an ESO key-program. Radial velocities have
been measured using a cross-correlation method, the templates being a
grid of synthetic spectra. The obtained precision depends on effective
temperature and projected rotational velocity of the star as well as
on a possible asymmetry of the correlation peak generally due to
secondary components. New spectroscopic binaries have been detected
from these a symmetries and the variability of the measured radial
velocity. Simulations of binary and triple systems have been
performed. For binaries our results have been compared with Hipparcos
binary data. Adding the variable radial velocities, the minimum binary
fraction has been found 60% for physical systems. Radial velocities
have been determined for 581 B8-F2 stars, 159 being new. Taking into
account published radial velocities, 39% south A-type stars with V
magnitude lower than 7.5 have a radial velocity.

Note (1): In the original table, HIP 17797B, HIP 43920B and HIP 46657B have
no position.
* For HIP 17797B and HIP 46657B, we added the Simbad coordinates of the
corresponding HD star.
* For HIP 43920B, we added the coordinates of HIP 43920A of this table.
Note (2): the flag has the following meaning:
0 = symmetric and gaussian peak
1 = SB2
2 = certain double, near spectral types
3 = certain double, A-B type with faint F-G component
4 = probable double
