Observations of carbon monoxide emission in NGC 5367.
Observations of the j = 1-0 transitions of `2C'6O, `3C'6O, and `2C'8O in NGC 5367 are reported. The CO line intensity contours lead us to conclude that the kinetic temperature peaks at the positions of two stars embedded in this molecular cloud, indicating that the gas is being heated by these stars. Photometric measurements on these stars suggest that they are of spectral type B. From the CO line intensities we estimate the mass of the molecular cloud to be d 30 M0. Assuming that these two embedded stars recently formed in this cloud, NGC 5367 is then an example of a relatively low mass cloud in which stellar formation may take place. Infrared and optical observations of these stars are suggested to test this hypothesis. Sabject headings: molecules, interstellar - nebulae, individual
