SCARFE, C. D.  y  GRIFFIN, R. F.. The Spectroscopic orbits of HD 23052 and HD 90512. Rev. mex. astron. astrofis [online]. 2012, vol.48, n.2, pp.251-256. ISSN 0185-1101.

We present radial-velocity observations from DAO and Cambridge, from which we derive orbital elements. HD 23052 is a G-type main-sequence object which has been regarded as a solar analogue, in an orbit of period nearly three years. HD 90512 is a G-type giant in a nearly circular orbit with a period just over 100 days.
