Observations unveil atomic hydrogen surrounding planetary nebulae, suggesting interaction with the interstellar medium.
Due to the contamination from omnipresent interstellar 21 cm emission, atomic hydrogen (H i) 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.
