... Comparative study of Tl-2201 single crystals with T c =30 and 110 K by means of X-ray structural analysis and NMR. Abstract: . The crystal structure of a tetragonal single crystal of Tl-2201 with T c =30 K has been determined by the X-ray diffraction technique ( a = 3.8717(3), c = 23.224(3) Angstrom, space group I4/mmm, Z = 2). The chemical composition is found to be Tl 1.90(1) Cu 0.10(1) Ba 2 CuO 6.18(4) . ... Structural parameters of Tl-2201 cuprates with various T c have been compared. ...

H I absorption, on the other hand, traces colder, denser gas that should be more confined in discrete clouds and perhaps discrete spiral arms. In addition, H I self-absorption (HISA) requires background H I emission at the same velocity as the foreground absorbing gas, thus introducing a much-needed constraint on the large-scale sightline geometry and kinematics. ...

We investigate models for main-sequence and horizontal-branch (HB) stars constructed using the Carson opacities and make comparisons with models based on the Cox-Stewart opacities. ... The drop in the hydrogen-shell luminosity due to the helium-core expansion during HB evolution is greater than that obtained with the Cox-Stewart opacities. ... Studies of main-sequence (MS) stars lead to agreement with Stothers' (1974a,b, 1976) results for homogeneous models constructed with Carson opacities. ...

We report the density structure of the ultracompact HII regions G35.20-1.74, G9.62+0.19-E, and G75.78+0.34-H2O. The density profiles are derived from radio continuum emission at wavelengths from 6 to 0.3cm. In the case of G35.20-1.74, a cometary UC HII region with a core and a tail, the spectrum of the core varies as Snu~nu^(0.6), implying that the density structure is ne~r^(-2). ...

... 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. ...
