Stellar Notes
ADS 4749A, spectrum variable. Sometimes shows shell features.
AB CPM. B is 6.94V, +0.04(B-V), -0.02(U-B), A0V, vsini 120k/s. Component C, 8.9v at 118". HD erroneously assigned the | preceding number, HD 42092, to the fainter following component of ADS 4749. Consequently the data for the two primary | components are sometimes interchanged. vsini for component A is 250k/s.
