Abstract

We apply the Sternberg et al. ([13] hereafter S14) theoretical model to analyze HI and H2 observations in the Perseus molecular cloud. We constrain the physical properties of the HI shielding envelopes and the nature of the Hi-to-H2 transitions. Our analysis (Bialy et al. [3]) implies that in addition to cold neutral gas (CNM), less dense thermally-unstable gas (UNM) significantly contributes to the shielding of the H2 cores in Perseus.
