We report the detection of a faint pointlike feature possibly related to ongoing planet-formation in the disk of the transition disk star HD 169142 .
The pointlike feature has a \Delta mag ( L ) \sim 6.4 , at a separation of \sim 0.11 \arcsec and PA \sim 0 ^ { \circ } .
Given its lack of an H or K _ { S } counterpart despite its relative brightness , this candidate can not be explained by purely photospheric emission and must be a disk feature heated by an as yet unknown source .
Its extremely red colors make it highly unlikely to be a background object , but future multi-wavelength followup is necessary for confirmation and characterization of this feature . Based on observations made with ESO Telescopes at the La Silla Paranal Observatory under programme ID 091.C-0572 . This letter includes data gathered with the 6.5 Magellan Telescopes located at Las Campanas Observatory ( LCO ) , Chile
