... Line radiative transfer in C 18 O, HCO + , and CS lines is considered in a spherically symmetric chemo-dynamical model of a starless core, evolution of which is driven by the ambipolar diffusion. Theoretical line profiles are compared to observational data on the well-known L1544 core, which is one of possible candidates for collapsing protostellar clouds. ... Comparison between modelled and observed spectra suggests that L1544 has flattened structure and is observed at some inclination. ...

. INTERBALL AURORAL KEY PARAMETERS AVAILABILITY . Intervals of available data are coded by blue color. To read availability charts user should know the descriptor ("name") of the KP subset of interest. Table annotations include also number of version for each subset. Plot resolution is exactly one pixel per hour. Data are considered as available if at least one data point is present during that hour.

A High School Curriculum in Astrobiology . Astrobiology is a truly integrated science. For example, when extreme environments of Earth are examined as a springboard to the search for life in the Solar System, other subjects?the biology of microorganisms, the chemistry of nutrients, the process of respiration, and the nature of autotrophic habitats?are intimately entwined and must be considered in one breath, albeit a long one. ...
