Since the discovery of its dusty disk in 1984, Beta Pictoris has become theprototype of young early-type planetary systems, and there are now variousindications that a massive Jovian planet is orbiting the star at ~ 10 AU.However, no planets have been detected around this star so far. Our goal was toinvestigate the close environment of Beta Pic, searching for planetarycompanion(s). Deep adaptive-optics L'-band images of Beta Pic were recordedusing the NaCo instrument at the Very Large Telescope. A faint point-likesignal is detected at a projected distance of ~ 8 AU from the star, within theNorth-East side of the dust disk. Various tests were made to rule out with agood confidence level possible instrumental or atmospheric artifacts. Theprobability of a foreground or background contaminant is extremely low, basedin addition on the analysis of previous deep Hubble Space Telescope images. Theobject L'=11.2 apparent magnitude would indicate a typical temperature of ~1500K and a mass of ~ 8 Jovian masses. If confirmed, it could explain the mainmorphological and dynamical peculiarities of the Beta Pic system. The presentdetection is unique among A-stars by the proximity of the resolved planet toits parent star. Its closeness and location inside the Beta Pic disk suggest aformation process by core accretion or disk instabilities rather than abinary-like formation process.
