Zb. Jiang et al., Observation and study of the CO molecular lines in infrared sources IRAS 05437-0001 and IRAS 05351+3549, CHIN ASTR A, 24(3), 2000, pp. 315-323
Using the 13.7 m radio telescope at Qinghai Observing Station of Purple Mou
ntain Observatory, CO(J=1-0) molecular spectral line observations in the re
gions around the infrared sources IRAS 05437-0001 and IRAS 05351+3549 were
carried out. It is discovered that there are very intense emissions in the
direction of these two sources.. And the CO spectral lines have conspicuous
wing components implying molecular outflows. For each source 5' x 5' maps
were obtained. By the observation and analysis of the space distribution of
high velocity gases, it is found that these sources are sources of molecul
ar outflow. Of the two, IRAS 05437-0001 exhibits a rather complicated struc
ture of outflow in its neighbouring region. It is possible that the outflow
here is multipolar in form. The structure of outflow around IRAS 05351+354
9 is simpler. From the classification of infrared spectra of the two source
s and the dynamic timescale of outflows, it is found that the stars are you
ng (with ages approximate to 10(5) yrs). From the parameters of the two out
flow sources, their mass loss rates are estimated.
