Abstract:
We report the results of a single-dish survey of molecular outflows
towards a homogeneous sample of 136 ultracompact HII regions for
which we had previously obtained observations in the methanol 6.7GHz
and water 22.2GHz maser lines. The line profiles of the 13CO J=1-0
and 2-1 transitions have been compared to those of the corresponding
lines of the C18O isotopomer to reveal the occurrence of line wings
and hence of molecular outflows.
description:
The observations were carried out with the IRAM 30-m telescope at Pico
Veleta (Granada, Spain) during several runs in April and August 2000.
