A is a Delta Scuti-type variable, TZ CrB, and double-lined
spectroscopic binary, P = 1.14d. It exhibits atmospheric and coronal
activity, and radio flares.

Berman (1941) has discussed the RV's.
A subsystem with a period of about 12 yr has repeatedly been
suspected (cf Baize 1976), and the third component has now been
detected by infrared speckle interferometry.
No evidence in the speckle or Hipparcos data for the large-amplitude
third-body orbit given by Baize.
