modern name for HD 33793 = GJ 191, a high proper motion M1 subdwarf at d=4pc (V=8.8). The star was unusual – very blue but M1 type, high pm and very high radial velocity (242 km/s). Two recent exoplanet candidates reported (Anglada-Escude+2014) but both have been rebutted (Bortles+2021).
Etymology and History
This was 2nd highest proper motion star in 1927 according to Luyten and still is! (8.7”/yr). It was pointed out as highest proper motion (at time) by Kapteyn (1897) “Stern mit grösster bislang bekannter Eigenbewegung” (“Star with largest self-motion known to date”)
The name appears to be from Luyten (1927) “Note on the Magnitude and Spectrum of Kapteyn's Star”.
