Physical conditions of the interstellar medium in galaxies are closely linked to the ambient radiation field and the heating of dust grains. ... The KINGFISH profiles are well suited to examining trends of dust temperature Tdust and нІ because they span a factor of ~200 in the ISRF intensity heating the bulk of the dust mass, Umin. Results from fitting the profile SEDs suggest that, on average, Tdust, dust optical depth о„dust, and Umin decrease with radius. ...

... Summarizing the results of the Hamburg/SAO survey presented in Papers I through V, we discovered altogether from the 1-st priority candidates 433 new emission-line objects (25 of them are QSOs), and for 85 known ELGs we got quantitative data for their emission lines. ... To estimate the total number of BCGs in the HSS zone we should count new BCGs expected from the remaining candidates and those selected in the HSS, but not observed by us since they already were known from other surveys. ...

In this new series we present observations and modelling of spectral lines formed in main sequence star chromospheres (from G0 to M8). in this paper, we discuss the Hydrogen line formations in very active dMe stellar chromospheres. ... Our final model atmosphere is described in the next paper in this series. ... We found that observations are best reproduced by a chromospheric structure including a constant temperature gradient (in a log(M) scale) in the chromosphere and transition region. ...

Saxton & Wu (1999) presented calculations of the stability of the accretion shock which forms on the surface of an accreting magnetic white dwarf in AM Herculis type systems in an attempt to explain the observed properties of the quasi periodic oscillations sometimes seen in these systems. He showed that radiative cooling may cause thermal instability in the post-shock structure of the accretion flow settling onto a magnetic white dwarf. ...
