The Behlen Observatory Variable Star Survey: Finding Charts And Light Curves For The First Ninety-Three Stars, Edward G. Schmidt, Darwin E. Reiswig Dec 1993

The Behlen Observatory Variable Star Survey: Finding Charts And Light Curves For The First Ninety-Three Stars, Edward G. Schmidt, Darwin E. Reiswig

Edward Schmidt Publications

In a previous paper, photometry for the first ninety-three stars in a photometric survey of variable stars was discussed. Finding charts, accurate coordinates, and light curves for those stars are presented here. The reliability of the coordinates from the General Catalogue of Variable Stars is discussed. The magnitude scale of the present photometry is compared with that of the Hubble Space Telescope Guide Star Catalogue.


Far-Ultraviolet Stellar Photometry: A Field In Orion, Edward G. Schmidt, George R. Carruthers Dec 1993

Far-Ultraviolet Stellar Photometry: A Field In Orion, Edward G. Schmidt, George R. Carruthers

Edward Schmidt Publications

Far-ultraviolet photometry for 625 objects in Orion is presented. These data were extracted from electrographic camera images obtained during sounding rocket flights in 1975 and 1982. The 1975 images were centered close to the belt of Orion while the 1982 images were centered ~9° further north. One hundred and fifty stars fell in the overlapping region and were observed with both cameras. Sixty-eight percent of the objects were tentatively identified with known stars using the SIMBAD database while another 24% are blends of objects too close together to separate with our resolution. As in previous studies, the majority of the ...


Far-Ultraviolet Stellar Photometry: A Field In Monoceros, Edward G. Schmidt, George R. Carruthers May 1993

Far-Ultraviolet Stellar Photometry: A Field In Monoceros, Edward G. Schmidt, George R. Carruthers

Edward Schmidt Publications

Far-ultraviolet photometry of stars in a field in Monoceros in the wavelength rang from 1230 Å to 1600 Å has been carried out using data from an electrographic Schmidt camera carried on a sounding rocket. Ultraviolet magnitudes were extracted for 602 objects in the field. Fifty-eight percent were tentatively identified with visible stars using the SIMBAD data base while another 25% are blends of objects too close together to separate with our resolution. Eleven of the uv objects coincide with parts of the star clusters NGC 2169, NGC 2244, and KGC 2264 in which individual stars cannot be resolved. As ...


The Behlen Observatory Variable Star Survey, Paper Iii, Edward G. Schmidt, John R. Chab, Darwin E. Reiswig Mar 1993

The Behlen Observatory Variable Star Survey, Paper Iii, Edward G. Schmidt, John R. Chab, Darwin E. Reiswig

Edward Schmidt Publications

Finding charts, accurate coordinates and light curves are presented for 146 variable stars including three which are newly discovered. Parameters descriptive of the light curves arc tabulated including periods for eight stars which lacked them in the General Catalogue of Variable Stars (the GCVS). GCVS periods of twelve stars were found to be seriously in error. The classification of the stars is discussed. Revisions or refinements of the classifications from the General Catalogue of Variable of Stars are suggested for thirty-one stars. Of the nineteen stars classified as Bailey type c RR Lyrae stars in the General Catalogue of Variable ...
