Methanol Abundance in Low Mass Protostars

نویسنده

  • Sébastien Maret
چکیده

Methanol lines observations of a sample of low mass Class 0 protostars are presented. Using a 1D radiative transfer model, I show that several protostars have large abundance jumps in the inner hot and dense region of envelopes, probably because of thermal grain mantle evaporation. These abundances are compared with a grain surface chemistry model.

CH 3 OH abundance in low mass protostars

We present observations of methanol lines in a sample of Class 0 low mass protostars. Using a 1-D radiative transfer model, we derive the abundances in the envelopes. In two sources of the sample, the observations can only be reproduced by the model if the methanol abundance is enhanced by about two order of magnitude in the inner hot region of the envelope. Two other sources show similar jumps...

Testing grain surface chemistry : a survey of deuterated formaldehyde and methanol in low-mass Class 0 protostars

Context. Despite the low cosmic abundance of deuterium (D/H ∼ 10−5), large degrees of deuterium fractionation in molecules are observed in star forming regions with enhancements that can reach 13 orders of magnitude, which current models have difficulties to account for. Aims. Multi-isotopologue observations are a very powerful constraint for chemical models. The aim of our observations is to u...

On the Identification of High Mass Star Forming Regions Using Iras: Contamination by Low-mass Protostars

We present the results of a survey of a small sample (14) of low-mass protostars (LIR < 103 L⊙) for 6.7 GHz methanol maser emission performed using the ATNF Parkes radio telescope. No new masers were discovered. We find that the lower luminosity limit for maser emission is near 103 L⊙, by comparison of the sources in our sample with previously detected methanol maser sources. We examine the IRA...

To appear in ApJS Water and Methanol Maser Survey of Protostars in the Orion Molecular Cloud Complex

The results of a maser survey toward ninety-nine protostars in the Orion molecular cloud complex are presented. The target sources are low-mass protostars identified from infrared observations. Single-dish observations were carried out in the water maser line at 22 GHz and the methanol class I maser lines at 44, 95, and 133 GHz. Most of the detected sources were mapped to determine the source p...

The methanol lines and hot core of OMC2-FIR4, an intermediate-mass protostar, with Herschel/HIFI*

In contrast with numerous studies on the physical and chemical structure of lowand high-mass protostars, much less is known about their intermediate-mass counterparts, a class of objects that could help to elucidate the mechanisms of star formation on both ends of the mass range. We present the first results from a rich HIFI spectral dataset on an intermediate-mass protostar, OMC2-FIR4, obtaine...
