Abstract:
We present adaptive optics (AO) assisted J, H, and K/K' images of
eight ultracompact HII (UC HII) regions taken with the ALFA (Adaptive
optics with a Laser For Astronomy) and ADONIS (ADaptive Optics
Near-Infrared System) AO systems at Calar Alto and La Silla
observatories. The images show details of the stellar population and
the near-IR morphology of UC HII regions with unprecedented
resolution.
Description:
The observations using the AO system ALFA on the 3.5m telescope at the
German-Spanish astronomical center on Calar Alto (Spain), were part of
the ALFA science verification program. This program was carried out
from fall 1999 to fall 2000. The ADONIS observations were carried out
in 2000 March.

Note (1): Flag on Name, defined as follows:
e = Several compact radio continuum sources are included
in the field of view of our near-IR images.
f = This source has two components. Both components are included
in the field of our near-IR images. Component A classified as
spherical, and component B as irregular.
Note (2): Right ascension and declination of the peak radio emission
taken from the literature (Equinox J2000).
Note (3): Radio morphological type from Wood & Churchwell (1989ApJS...69..831W 1989ApJS...69..831W),
Walsh et al. (1997, Cat. J/MNRAS/291/261), and Kurtz et al.
(1994, Cat. J/ApJS/91/659), depending on the source.
The codes used have the following meaning:
UN = Unresolved/spherical,
CO = cometary,
CH = core-halo,
SH = shell,
IR = irregular/multipeaked.
