Spectroscopic characterization of the known O-star population in Cygnus OB2. Evidence of multiple star-forming bursts
S. R. Berlanas, A. Herrero, F. Comerón +6
Cygnus OB2 provides a unique insight into the high-mass stellar content in one of the largest groups of young massive stars in our Galaxy. Although several studies of its massive p…
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…
LiLiMaRlin, a Library of Libraries of Massive-Star High-Resolution Spectra with applications to OWN, MONOS, and CollDIBs
J. Maíz Apellániz, E. Trigueros Páez, I. Jiménez Martínez +5
LiLiMaRlin is a library of libraries of massive-star high-resolution optical spectra built by collecting data from [a] our spectroscopic surveys (OWN, IACOB. NoMaDS, and CAFÉ-BEANS…
Var C: Long-term photometric and spectral variability of an LBV in M33
B. Burggraf, K. Weis, D. J. Bomans +6
So far the highly unstable phase of luminous blue variables (LBVs) has not been understood well. It is still uncertain why and which massive stars enter this phase. Investigating t…
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…
CAFÉ-BEANS: An exhaustive hunt for high-mass binaries
I. Negueruela, J. Maíz Apellániz, S. Simón-Díaz +11
CAFÉ-BEANS is an on-going survey running on the 2.2 m telescope at Calar Alto. For more than two years, CAFÉ-BEANS has been collecting high-resolution spectra of early-type stars w…
