Abstract
B, V and I light curves of the eclipsing binaries HV12634 in the LMV, and HV2208 in the SMC (cf. West et al., 1992), have been analysed with the aid of optimal curve-fitting techniques. Parameter derivation inv olves aa successive approximations procedure. The results of this are combined with aa standard mass:luminosity relation to explore tentativ e absolute parameters. The combined evidence shows some disparity with standard MS-like models. It also demonstrates some relative insensiti vity of photometric analysis, in isolation, to elucidate clear facts o n such possibly atypical, remote. hot stars. Auxilliary spectroscopic data are required to resolve remaining ambiguities.
