Direct mass ratio determination in the SB2 systems HD 108642 and HD 434.
BUDAJ J., ILIEV I.K., BARZOVA I.S., ZIZNOVSKY J., ZVERKO J. and STATEVA I.
Abstract (from CDS):
We confirm the presence of the secondary spectrum in two SB2 systems: HD 108642 and HD 434. Lines of both components in both systems are clearly travelling and crossing. This enabled us to improve the previous mass ratio estimate in the case of HD 108642 and to determine it for the fist time in HD 434.
