Young T-dwarf candidates in IC 348
Context: The determination of the lower-end of the initial mass function (IMF) provides strong constraints on star formation theories. Aims: We report here on a search for isolated planetary-mass objects in the 3 Myr-old star-forming region IC 348. Methods: Deep, narrowband CH4off and CH4on images were obtained with CFHT/WIRCam over 0.11 sq. deg
