Problems of Star Formation Theory and Prospects of Submillimeter Observations
D. Z. Wiebe, M. S. Kirsanova, B. M. Shustov +1
We consider current state of star formation theory and requirements to observations in millimeter and submillimeter ranges which are necessary for resolution of the most actual pro…
Do we need to know the temperature in prestellar cores?
Ya. Pavlyuchenkov, Th. Henning, D. Wiebe
Molecular line observations of starless (prestellar) cores combined with a chemical evolution modeling and radiative transfer calculations are a powerful tool to study the earliest…
Gas-phase CO in protoplanetary disks: a challenge for turbulent mixing
D. Semenov, D. Wiebe, Th. Henning
This is the first paper in a series where we study the influence of turbulent diffusion and advective transport on the chemical evolution of protoplanetary disks, using a 2D flared…
CB17: Inferring the dynamical history of a prestellar core with chemo-dynamical models
Ya. Pavlyuchenkov, D. Wiebe, R. Launhardt +1
We present a detailed theoretical study of the isolated Bok globule CB17 (L1389) based on spectral maps of CS, HCO, CO, CS, and HCO lines. A phenomenol…
Reduction of chemical networks. II. Analysis of the fractional ionisation in protoplanetary discs
D. Semenov, D. Wiebe, Th. Henning
(abridged) We analyse the evolution of the fractional ionisation in a steady-state protoplanetary disc with a vertical temperature gradient and with gas-grain chemistry including s…
Reduction of chemical networks. I. The case of molecular clouds
D. Wiebe, D. Semenov, Th. Henning
We present a new method to analyse and reduce chemical networks and apply this technique to the chemistry in molecular clouds. Using the technique, we investigated the possibility…
