Strömgren photometry of the delta Sct star V919 Her.
Preliminary analysis of photometric observations carried out during 2003and 2004 photometric campaigns of the delta Sct-type star V919 Her ispresented. Analysis of the data, using the Fourier transform method,showed that the two dominant frequencies do agree well with the twofrequencies found by Koen (2001). A very complicated frequency spectrumis obtained which suggests the convenience of organizing a coordinatedcampaign to disentangle the frequencies content.
| The Hercules H I shell - Distances of the gas clouds and topography of the shell
The structure and distances of high-latitude (l between 35 and 75 deg)neutral gas clouds constituting the galactic H I shell GS 57 + 41(which, due to its location in the constellation of Hercules was named'Hercules shell') are investigated, using the results of an extensivesurvey of interstellar Na I D absorption lines to determine distances tothe various neutral clouds and filaments in this field of the sky. Basedon the distances, conclusions are drawn with regard to the morphologicalstructure and the physical parameters of the GS 57 + 41. The results ofoptical high-resolution absorption and 21 cm emission line measurementsof the various H I clouds were compared with the cirrus of IRAS 100micron dust emission, as well as with the diffuse X-ray backgroundemission in this area.
