The link between gas and stars in the S254-S258 star-forming region
D. A. Ladeyschikov, M. S. Kirsanova, A. M. Sobolev +5
The paper aims to study relation between the distributions of the young stellar objects (YSOs) of different ages and the gas-dust constituents of the S254-S258 star-formation compl…
On the methanol emission detection in the TW Hya disc: the role of grain surface chemistry and non-LTE excitation
S. Yu. Parfenov, D. A. Semenov, Th. Henning +3
The recent detection of gas-phase methanol (CHOH) lines in the disc of TW Hya by Walsh et al. provided the first observational constraints on the complex O-bearing organic cont…
Chemistry in Protoplanetary Disks: A Sensitivity Analysis
A. I. Vasyunin, D. Semenov, Th. Henning +3
We study how uncertainties in the rate coefficients of chemical reactions in the RATE06 database affect abundances and column densities of key molecules in protoplanetary disks. We…
Search for radiative pumping lines of OH masers: I. The 34.6um absorption line towards 1612 MHz OH maser sources
J. H. He, R. Szczerba, P. S. Chen +1
The 1612 MHz hydroxyl maser in circumstellar envelopes has long been thought to be pumped by 34.6um photons. Only recently, the Infrared Space Observatory has made possible spectro…
Model of the W3(OH) environment based on data for both maser and 'quasi-thermal' methanol lines
A. M. Sobolev, E. C. Sutton, D. M. Cragg +1
In studies of the environment of massive young stellar objects, recent progress in both observations and theory allows a unified treatment of data for maser and 'quasi-thermal' lin…
On the Influence of Uncertainties in Chemical Reaction Rates on Results of the Astrochemical Modelling
A. I. Vasyunin, A. M. Sobolev, D. S. Wiebe +1
With the chemical reaction rate database UMIST95 (Millar et al. 1997) we analyze how uncertainties in rate constants of gas-phase chemical reactions influence the modelling of mole…
