Description
Ionization rate is one of the most important parameters controlling both the chemical and dynamical processes in protoplanetary disks. What few observational constrains on ionization currently exists suggest overall low ionization, limiting the processes able to take place. I will present new NOEMA observations which, when combined with chemical modeling, are indicative of enhanced ionization rates in the envelopes of three Class I protostars. I will then discuss the potential impact of this early enhancement on the evolution of protoplanetary disks.
