", "abstract": "A photometer employing a liquid hydrogen-cooled mercury-doped germanium photoconductor whose spectral response is limited to the 8 - 14 \u00b5 region by a low pass interference filter and a BaF_2 window coupled with the\ncell's threshold wavelength has been placed at the east arm Cassegrain focus of the 200 inch Hale telescope.\nTwenty-five stars have been measured. The earliest star for which two measurements have been obtained is the B8Ia star \u03b2 Orionis. The latest star is the M7e star X Cygni. The brightest star, L37 X 10^(-14) watts/cm^2, is \u03b1 Orionis. The carbon star DS Peg was also measured. In a two-color diagram formed with B and V there is an intrinsic increase\nin dispersion going to later type stars and a systematic trend away from the blackbody relation. The ratios of the stellar fluxes to those expected from blackbodies at the published stellar effective-temperatures and angular diameters are not far from one. A systematic trend exhibited\nmay not be real because of the assumptions involved in inteferometric diameter determinations. DS Peg does not appear overly peculiar in the two-color plots, but X,Cygni falls on the opposite side of the blackbody curve (\"blue excess\") compared with most of the late type stars.\nThe fluxes presented here have not been corrected for presently uncertain telescope transmission losses which may be important.", "date": "2012-09-21", "date_type": "published", "publisher": "California Institute of Technology", "id_number": "CaltechAUTHORS:20120921-080107787", "official_url": "https://resolver.caltech.edu/CaltechAUTHORS:20120921-080107787", "rights": "No commercial reproduction, distribution, display or performance rights in this work are provided.", "funders": { "items": [ { "agency": "NASA", "grant_number": "NsG 56-60" }, { "agency": "NSF", "grant_number": "G-25210" } ] }, "other_numbering_system": { "items": [ { "id": "CR-50143", "name": "NASA Technical Report" } ] }, "primary_object": { "basename": "MURjpltr1963007152.pdf", "url": "https://authors.library.caltech.edu/records/cq0qc-k5r59/files/MURjpltr1963007152.pdf" }, "resource_type": "monograph", "pub_year": "2012", "author_list": "Wildey, Robert L. and Murray, Bruce C." }, { "id": "https://authors.library.caltech.edu/records/cet4g-yrk13", "eprint_id": 27929, "eprint_status": "archive", "datestamp": "2023-08-19 09:12:27", "lastmod": "2023-10-24 17:31:05", "type": "monograph", "metadata_visibility": "show", "creators": { "items": [ { "id": "Murray-B-C", "name": { "family": "Murray", "given": "B.
