Mel. Hopwood et al., SEARCH FOR CO J=2-]1 EMISSION FROM THE METAL-RICH GLOBULAR-CLUSTER NGC-6356, Astrophysics and space science, 251(1-2), 1997, pp. 385-388
We have observed the metal-rich globular cluster NGC 6356 in the CO J
= 2 --> 1 transition. The data revealed no apparent emission correspon
ding to the radial velocity of the cluster and we present an upper lim
it to the mass of gas in the cluster core.
