Resumen
We present high angular resolution (0.1 arcsec ) VLA observations at 7 mm wavelength towards the planetary nebula with bipolar morphology IC 4997. We detect a compact central structure possibly associated with the inner core reported by Miranda & Torrelles (1998) and discuss whether or not this detection is related to dust emission. The spectral index of the central region has also been derived using observations at other frequencies made with similar angular resolution.
