Physical properties of seven binary and higher-order multiple OB systems
Physical properties of seven binary and higher-order multiple OB systems
Analyses of multi-epoch, high-resolution (R ~ 50 000) optical spectra of seven early-type systems provided various important new insights with respect to their multiplicity. First determinations of orbital periods were made for HD 92206 C (2022), HD 112244 (27665), HD 164438 (1025), HD 123056 A (~1314 d) and HD 123056 …
