DESCRIPTION:Speakers: Kamber Schwarz (University of Arizona)\nIonization r
 ate is one of the most important parameters controlling both the chemical 
 and dynamical processes in protoplanetary disks. What few observational co
 nstrains on ionization currently exists suggest overall low ionization\, l
 imiting the processes able to take place. I will present new NOEMA observa
 tions which\, when combined with chemical modeling\, are indicative of enh
 anced ionization rates in the envelopes of three Class I protostars.  I wi
 ll then discuss the potential impact of this early enhancement on the evol
 ution of protoplanetary disks.\n\nhttps://meetings.aip.de/event/1/contribu
