Spectral classification
J. Maíz Apellániz, I. Negueruela, J. A. Caballero
Spectral classification is the division of stars into classes based on their spectral characteristics. Different classification systems have existed since the 19th century but the…
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…
Ultracool dwarf benchmarks with \emph{Gaia} primaries
F. Marocco, D. J. Pinfield, N. J. Cook +14
We explore the potential of \emph{Gaia} for the field of benchmark ultracool/brown dwarf companions, and present the results of an initial search for metal-rich/metal-poor systems.…
The substellar population of Sigma Orionis: A deep wide survey
V. J. S. Béjar, M. R. Zapatero Osorio, R. Rebolo +5
We present a deep I,Z photometric survey covering a total area of 1.12 deg^{2} of the Sigma Orionis cluster (Icompl=22 and Zcompl=21.5mag). From I, I-Z color-magnitude diagrams we…
Near-infrared Linear Polarization of Ultracool Dwarfs
M. R. Zapatero Osorio, V. J. S. Béjar, B. Goldman +5
We report on near-infrared J- and H-band linear polarimetric photometry of eight ultracool dwarfs (two late-M, five L0-L7.5, and one T2.5) with known evidence for photometric varia…
Near-infrared low-resolution spectroscopy of Pleiades L-type brown dwarfs
G. Bihain, R. Rebolo, M. R. Zapatero Osorio +2
The fundamental properties of brown dwarfs evolve with age. Models describing the evolution of luminosities and effective temperatures, among other physical parameters, can be empi…
