Context. Many massive stars have nearby companions whose presence hamper their characterization through spectroscopy. Aims. We want to obtain spatially resolved spectroscopy of close massive visual binaries to derive their spectral types. Methods. We obtained a large number of short long-slit spectr...

Context. Many massive stars have nearby companions whose presence hamper their characterization through spectroscopy. Aims. We want to obtain spatially resolved spectroscopy of close massive visual binaries to derive their spectral types. Methods. We obtained a large number of short long-slit spectroscopic exposures of five close binaries under good seeing conditions. We selected those with the best characteristics, extracted the spectra using multiple-profile fitting, and combined the results to derive spatially separated spectra. Results. We demonstrate the usefulness of Lucky Spectroscopy by presenting the spatially resolved spectra of the components of each system, in two cases with separations of only ~0.′′3. Those are δ Ori Aa+Ab (resolved in the optical for the first time) and σ Ori AaAb+B (first time ever resolved). We also spatially resolve 15 Mon AaAb+B, ζ Ori AaAb+B (both previously resolved with GOSSS, the Galactic O-Star Spectroscopic Survey), and η Ori AaAb+B, a system with two spectroscopic B+B binaries and a fifth visual component. The systems have in common that they are composed of an inner pair of slow rotators orbited by one or more fast rotators, a characteristic that could have consequences for the theories of massive star formation. |

Lucky Spectroscopy, an equivalent technique to Lucky Imaging Spatially resolved spectroscopy of massive close visual binaries using the William Herschel TelescopeMaíz Apellániz, J.Barbá, R. H.Simón Díaz, S.Sota, A.Trigueros Páez, E.Caballero, J. A.Alfaro, Emilio J. Binaries: spectroscopicBinaries: visualMethods: data analysisStars: early typeStars: massiveTechniques: spectroscopicContext. Many massive stars have nearby companions whose presence hamper their characterization through spectroscopy. Aims. We want to obtain spatially resolved spectroscopy of close massive visual binaries to derive their spectral types. Methods. We obtained a large number of short long-slit spectroscopic exposures of five close binaries under good seeing conditions.

The systems have in common that they are composed of an inner pair of slow rotators orbited by one or more fast rotators, a characteristic that could have consequences for the theories of massive star formation.As we were about to submit this paper, we received the sad news of the death of Nolan R. Walborn after a long battle with cancer. As he was the inspiration for GOSSS, we would like to dedicate this paper to him. May he rest in peace. This work has made use of the Washington Double Star Catalog (Mason et al. 2001). The authors would like to thank the personnel of the Isaac Newton Group of telescopes for their support throughout the years, with a special mention to Cecilia Fariña for her help with the setup for Lucky Spectroscopy. The first author is amazed that the instrument he used for his PhD Thesis is still working one quarter of a century later and is not yet surpassed in some of its characteristics.
