Abstract:
Radial velocity curves for 15 bright subdwarf B binary systems have
been measured using high precision radial velocity measurements from
high S/N optical high-resolution spectra. In addition, two bright sdB
stars are discovered to be radial velocity variable but the period
could not yet be determined. The companions for all systems are
unseen.
Description:
Table 3 lists the radial velocity measurements for our program stars.
