Observational analysis of 21 giant stars shows Fe I+Fe II blend emission proportional to Ca II K with matching Teff power-law exponent and a slope break in the flux ratio at log g ≈ 2.5.
HD3191 is a single rapidly rotating B1 IV:nn star showing multi-mode non-radial pulsations, not a high-mass X-ray binary.
