Description

Absolute dimensions and the distance modulus have been established for the early-type eclipsing binary HV 2226 in the SMC. Analyses of the new radial velocities reported here, and CCD light curves published by previous authors, yield component masses of 9.3 ± 0.7 and 5.6 ± o.5 solar masses respectively. The radii are 5.6 ± 0.2 and 5.3 ± 0.2 solar radii. A distance modulus of (mv-Mv)o = 18.6 ± 0.3 mag is derived, marginally lower than the adopted mean of 18.9 mag for the SMC. The position of HV 2226, however, indicates that it is in fact situated in the near side of the SMC. (author)
