  • Context. Sirius is the brightest star in the sky and a strong source of diffuse light for modern telescopes so that the immediate surroundings of the star are still poorly known. Aims. We study the close surroundings of the star (2 to 25 �� ) by means of adaptive optics and coronographic device in the near-infrared, using the ESO/ADONIS system. Methods. The resulting high contrast images in the JHKs bands have a resolution of ∼0.2 �� and limiting apparent magnitude ranging from mK = 9. 5a t 3… CONTINUE READING
