Abstract:
Orbital elements have been determined for 10 chromospherically active
binaries from a combination of new velocities and velocities in the
literature. First orbits for three binaries, HD 33363, HD 152178, and
HD 208472, are presented, as well as updated orbits for seven other
binaries. Two of the latter systems, LN Peg and HD 106225 were
discovered to be triple, and both short- and long-period orbits have
been computed for each. Fundamental properties have been determined
for the chromospherically active primary in each system.
