Abstract

Due to the contamination from omnipresent interstellar 21 cm emission, atomic hydrogen (H <sc>i</sc>) associated with planetary nebulae (PNe) has been insufficiently investigated. In this proceeding we report a project of searching for H i surrounding PNe using the Five hundred-meter Aperture Spherical radio Telescope (FAST), which is the most sensitive single-dish telescope at L-band. The observations may offer new insights into the interaction processes between PNe and the interstellar medium.
