Abstract
We report the detection of a possible subsolar mass companion to the triple young system TY?CrA using the NACO instrument at the VLT UT4 during its commissioning. Assuming for TY?CrA a distance similar to that of the close binary system HD?176386, the photometric spectral type of this fourth stellar component candidate is consistent with an ~M 4 star. We discuss the dynamical stability of this possible quadruple system as well as the possible location of dusty particles inside or outside the system.
