Fast search for circumstellar atomic hydrogen
Webdemonstrates the feasibility of using FAST to search for atomic hydrogen in a large sample of PNe and to reveal new insights into the so- called PN missing mass problem. WebTo fill this gap, we present a combined crossed molecular beam, high-level ab initio, and astrochemical modeling investigation on the formation of (hydrogenated) circumstellar …
