Dynamical and chemical properties of the "starless" core L1014
A. Crapsi, C. H. DeVries, T. L. Huard +10
Spitzer Space Telescope observations of a point-like source, L1014-IRS, close to the dust peak of the low-mass dense core L1014 have questioned its starless nature. The presence of…

Probing the evolutionary status of starless cores through N2H+ and N2D+ observations
A. Crapsi, P. Caselli, C. M. Walmsley +4
We have undertaken a survey of N2H+ and N2D+ towards 31 low-mass starless cores using the IRAM 30m telescope. Our main objective has been to determine the abundance ratio of N2D+ a…
