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…
Orbital and physical properties of the Ori Aa,Ab,B triple system
Simón-Díaz, J. A. Caballero, J. Lorenzo +11
We provide a complete characterization of the astrophysical properties of the Ori Aa,Ab,B hierarchical triple system, and an improved set of orbital parameters for the highly e…
MGB and the new Galactic O-Star Spectroscopic Survey spectral classification standard grid
J. Maíz Apellániz, E. J. Alfaro, J. I. Arias +9
In this poster we present three developments related to the Galactic O-Star Spectroscopic Survey (GOSSS). First, we are making public the first version of MGB, an IDL code that all…
New galactic star clusters discovered in the VVV survey. Candidates projected on the inner disk and bulge
J. Borissova, A. -N. Chené, S. Ramírez Alegría +21
VISTA Variables in the Vía Láctea (VVV) is one of six ESO Public Surveys using the 4 meter Visible and Infrared Survey Telescope for Astronomy (VISTA). The VVV survey covers the Mi…
Massive open star clusters using the VVV survey III: A young massive cluster at the far edge of the Galactic bar
S. Ramírez Alegría, J. Borissova, A. N. Chené +14
Context: Young massive clusters are key to map the Milky Way's structure, and near-IR large area sky surveys have contributed strongly to the discovery of new obscured massive stel…
A Be-type star with a black hole companion
J. Casares, I. Negueruela, M. Ribo +4
Stellar-mass black holes have all been discovered through X-ray emission, which arises from the accretion of gas from their binary companions (this gas is either stripped from low-…
