Scientific paper

Orbits are presented for four ninth-magnitude stars about which the only
spectroscopic datum previously known is the HD type, K0 in each case.
There is circumstantial evidence that all the stars are giants and that
one of them (HD149240) has a hotter companion which should be detectable
spectroscopically and photometrically.
