Search of nearby resolved neutron stars among optical sources
Gabriel Bihain
Neutron stars are identified as pulsars, X-ray binary components, central objects of supernovae remnants, or isolated thermally emitting sources, and at distances beyond 120 pc. A…
GTC/CanariCam deep mid-infrared imaging survey of northern stars within 5 pc
Bartosz Gauza, Víctor J. S. Béjar, Rafael Rebolo +7
In this work we present the results of a direct imaging survey for brown dwarf companions around the nearest stars at the mid-infrared 10 micron range (=8.7m, =1.1…
A non-uniform distribution of the nearest brown dwarfs
G. Bihain, R. -D. Scholz
The census of solar neighbours is still complemented by new discoveries, mainly of very low-mass, faint dwarfs, close to or within the substellar domain. These discoveries contribu…
Constraints on the substellar companions in wide orbits around the Barnard's Star from CanariCam mid-infrared imaging
B. Gauza, V. J. S. Béjar, R. Rebolo +6
We have performed mid-infrared imaging of Barnard's Star, one of the nearest stars to the Sun, using CanariCam on the 10.4 m Gran Telescopio Canarias. We aim to investigate an area…
Stellar rotation, binarity, and lithium in the open cluster IC4756
Klaus G. Strassmeier, Joerg Weingrill, Thomas Granzer +3
An important aspect in the evolutionary scenario of cool stars is their rotation and the rotationally induced magnetic activity and interior mixing. Stars in open clusters are part…
Spectroscopic follow-up of L- and T-type proper-motion member candidates in the Pleiades
M. R. Zapatero Osorio, V. J. S. Béjar, E. L. Martín +9
(Abridged) We report on the near-infrared low-resolution spectroscopy and red optical (Z-band) photometry of seven proper-motion, very low-mass substellar member candidates of the…
