Scientific paper

We present an analysis of the main-sequence stars of compact multiple systems (Breysacher 73, LH10-3209, NGC2044 and HD32228) located at the Large Magellanic Cloud (LMC). For this purpose we calculated synthetic spectra and compared them with the spacially resolved (0''.1) spectroscopic data obtained by means of the Faint Object Spectrograph (FOS) aboard the Hubble Space Telescope (HST). Uncontaminated spectrograms of the individual stars enable us to study their basic parameters, like effective temperature, surface gravity, metal abundance parameter ([m/H]), etc. The results are discussed in the context of stellar contents and evolution of the compact OB groups in LMC.
