El cúmulo abierto alrededor de la estrella η Carinae

The photoelectric observations made during the current year (1964) shows that all stars in a radius of 5' around η Carinae are members of the open cluster Trumpler 16. The brightest star, HD 93250, of spectral type 05 is on the zero age main sequence. One Wolf-Rayet star, HD 93162, would appear...

description The photoelectric observations made during the current year (1964) shows that all stars in a radius of 5' around η Carinae are members of the open cluster Trumpler 16. The brightest star, HD 93250, of spectral type 05 is on the zero age main sequence. One Wolf-Rayet star, HD 93162, would appear to be a member of the cluster, if we assume that besides the absorption of all the group, there is an additional absorption of Aᵥ=O.6 mag. With an extra color excess of E(B-V)= 0.2 mag, this star is in the color-magnitude diagram very near HD 93250. Then, its absolute magnitude is Mᵥ = -5.5. Other two stars in the cluster, CD -59.3308 deg and 331o, may also have some additional absorption of around Aᵥ= 0.3 mag.
