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. ...

... Programme . ... Abstract: Chandra data taken as part of the Very Large Program (VLP) show that the X-ray spectrum in Centaurus A's jet steepens with increasing distance from the jet axis. ... Electrons with sufficient energy to emit synchrotron X-rays must be accelerated locally to the knots, since their energy loss timescale is short compared with any dynamical timescale associated with fluid motion. ...

. Authors: A.A. Suchkov , V.A. Marakov . Journal: Pis'ma Astron. Zh., 1976, v.2, p.38-385. Metallisity function of globular clusters in the Galaxy is constructed. It is found to have three "humps". This leads to a conclusion that there were three metal enrichment outbursts during the period of globular cluster formation. The constraints on the nature of metal sourses and on the early evolution of Galaxy are considered.

... For instance, known errors in the line locations, as well as missing lines with only minimal information, can be included directly during fitting. ... The Markov Chain Monte Carlo based method also naturally produces error estimates on the fit parameters.1 Keywords: Differential Emission Measures, Emissivity Matrix, Atomic Data Error, Capella INTRODUCTION The differential emission measures (DEMs) is the distribution of the amount of material in coronae as a function of temperature. ...

... 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. ...

Nongravitational Effects on Cometary Motion due to Jupiter . ... The problem of linking cometary apparitions before and after the approach of a comet to Jupiter was investigated. A hypothesis of possible existence of additional acceleration, perturbing the motion of comets in the vicinity of Jupiter, was considered. This nongravitational perturbation is described by a function of the jovicentric distance, written in a standard "force law" form. ...

... As a result of BTA observations of 23 chemically peculiar stars with strong magnetic fields, it was found that in 22 of them the longitudinal magnetic field, measured from the hydrogen line cores are considerably lower (by about 1/3) than the value measured from metal lines in the same spectra. ...

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). ...
