Quilt of the ultracompact HII region G34.26+0.15 by
Debra Shepherd (NRAO)
This quilt is a rendition of 3.6-cm (8.4 GHz) radio continuum data taken
by D. Wood & E. Churchwell at the VLA
(Van Buren et al. 1990, ApJ 353, 570) . Other images at 2 and 6 cm
are published by
Wood & Churchwell (1989), ApJS 69, 831. This object is the prototype
for cometary, ultracompact HII regions; it is believed that a massive, early
B star is forming within this cloud (Hunter et al. 1998), which is moving
supersonically and creating a bow shock.
From Van Buren et al. (1990).
