Query: The kinetic temperature of Barnard 68   We have observed the nearby isolated globule Barnard 68 (B68) in the
(J,K)=(1,1) and (2,2) inversion lines of ammonia. The gas kinetic temperature
derived from these is T=10+-1.2 K. The observed line-widths are almost thermal:
DV=0.181+-0.003 km/s (DVtherm=0.164+-0.010 km/s), supporting the earlier
hypothesis that B68 is in hydrostatic equilibrium. The kinetic temperature is
an input parameter to the physical cloud model put forward recently, and we
discuss the impact of the new value in this context.
