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…
A "Starless" Core that Isn't: Detection of a Source in the L1014 Dense Core with the Spitzer Space Telescope
C. H. Young, J. K. Joergensen, Y. L. Shirley +27
We present observations of L1014, a dense core in the Cygnus region previously thought to be starless, but data from the Spitzer Space Telescope shows the presence of an embedded s…
Observations of L1521F: a highly evolved starless core
A. Crapsi, P. Caselli, C. M. Walmsley +4
We observed the pre-stellar core L1521F in dust emission at 1.2mm and in two transitions each of N2H+, N2D+, C18O, and C17O in order to increase the sample of well studied centrall…
