  We present new, high angular resolution images of HD 199143 in the
Capricornus association, obtained with the adaptive optics system
ADONIS+SHARPII at the ESO 3.6m Telescope of La Silla Observatory. HD 199143 and
its neighbour star HD 358623 (separation 5'away) have previously been imaged
with adaptive optics. For each star, a companion has been detected in the J and
K bands at respective separations of 1.1'' and 2.2'' (Jayawardhana & Brandeker
2001). Our new photometry of HD 199143 B suggests that it is a M2 star and that
the presence of circumstellar dust proposed by Van den Ancker et al. (2000) is
no longer necessary. We show that the 12 microns flux detected by IRAS
previously interpreted as an IR excess, can be explained by the presence of the
late-type companion.
