MONOS: Multiplicity Of Northern O-type Spectroscopic systems. I. Project description and spectral classifications and visual multiplicity of previously known objects
J. Maíz Apellániz, E. Trigueros Páez, I. Negueruela +14
[ABRIDGED] AIMS. MONOS is collecting information and studying O-type spectroscopic binaries with delta > -20 deg. In this 1st paper we describe the sample and provide spectral clas…
The massive multiple system HD 64315
J. Lorenzo, S. Simon-Diaz, I. Negueruela +4
The O6 Vn star HD 64315 is believed to belong to the star-forming region known as NGC 2467, but previous distance estimates do not support this association. We explore the multiple…
GU Mon, a high-mass eclipsing overcontact binary in the young open cluster Dolidze 25
J. Lorenzo, I. Negueruela, F. Vilardell +3
Context. The eclipsing binary GU Mon is located in the star-forming cluster Dolidze 25, which has the lowest metallicity measured in a Milky Way young cluster. Aims. GU Mon has bee…
The little-studied cluster Berkeley 90. I. LS III +46 11: a very massive O3.5 If* + O3.5 If* binary
J. Maíz Apellániz, I. Negueruela, R. H. Barbá +9
Context: It appears that most (if not all) massive stars are born in multiple systems. At the same time, the most massive binaries are hard to find due to their low numbers through…
