Constraints on the substellar companions in wide orbits around the Barnard's Star from CanariCam mid-infrared imaging
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 within 1-10 arcsec separations, which for the 1.83 pc distance of the star translates to projected orbital separations of 1.8-18 au (P > 12 yr), which have not been
