discov_num notes refcode
CHR 153 1991.9021: Reprocessing of archival speckle data have confirmed this
already strong detection and have shown a change in theta of 15 deg in
2.7 yr. CHR 153 cannot be the 2-yr spectroscopic system of Griffin Grf1988
et al. (1988). In the Hyades. Msn1993a
The preliminary orbital solution is clearly in error as the visual Ole2003b
companion shows only linear motion. It can be another member of the Hrt2012a
Hyades or a wide pair in projection. The acceleration could be Hrt2012a
produced by the 1.8 yr SB companion. Tok2012a
This is not the 734.2-d spectroscopic binary of Griffin but a more Grf2012b
distant companion.
Rectilinear solution by Hartkopf et al. (2012). Hrt2012a
