Diffusion Limitations to I[sub 3][sup −]/I[sup −] Electrolyte Transport Through Nanoporous TiO[sub 2] Networks Open
Diffusion limitations due to triiodide transport through nanoporous networks are investigated with the help of a simple device structure, a nanoporous layer directly sintered onto a platinum electrode and immersed in an electrolyte solutio…

The distribution of (B-V) in two star catalogs Open
Graphical representations of the distribution of (B-V) in data bases of catalogs are shown. The sources are the Yale Bright Star Catalog (Hoffleit, 1982) and its supplement Hoffleit et al.,1983 plus the Navy UbV Catalog (Blanco et al., 196…

Integrated photometry and light distribution of 21 Southern-Hemisphere galactic globular clusters Open
Total magnitudes and brightness distributions were determined by computer analysis of multiaperture observations of 21 galactic globular clusters made in 1960-1961 at the Mount Stromlo Observatory. The results were compared with the Kron a…

Brightness profiles for 69 globular clusters determined by means of the electronic camera Open
The present 109 partial profiles are of the surface brightness of 69 globular clusters. All but two were determined by PDS microphotometry of electronic camera recordings. Some objects were recorded through UBV filters, while others were r…

Surface Brightness Profiles of 68 Globular Clusters Derived From Electronic Camera Recordings Open
Images of 68 globular clusters have been recorded in 125 exposures made with the electronic camera of the U.S. Naval Observatory on the 24-inch, 40-inch and 61-inch reflecting telescopes at the Flagstaff Station. The images were electronic…

Electrographic UBV Photometry of the Jet in 3C 273 Open
Magnitudes in the UBV system have been determined for the jet in 3C 273 by means of the electronic camera. The precision of the magnitudes is limited by the determination of that portion of the background light contributed by scattering an…

25. Stellar Photometry Open
During the past three years there has been increased activity in many fields where photometric methods are employed; more telescopes have been commissioned or adapted for photometric measurements and new magnitude systems have been propose…

The Observation of Monochromatic Intensity Distributions in Planetary Nebulae by Means of Electronography Open
The linear response and high information gain of the electronographic process make it an important new technique for the observation of monochromatic intensity distributions in planetary nebulae. Preliminary results for NGC 6720, obtained …

The Determination of Stellar Magnitudes by Electronography Open
The application of electronography to stellar photometry is investigated, and it is shown that a linear relationship between the area under the density profile of the star image and the intensity of the star exists over a range of at least…

Electronic Camera Studies of the Light Distribution in M 13 and M 15 Open
The radial distribution of surface brightness has been measured for M 13 and M 15 by means of electrographic plates. The surface brightness of M 15 follows the inverse-fourth-power law of de Vaucouleurs quite closely over a very large rang…

A Photometric Study of the Globular Cluster 47 Tucanae Open
During an eight-month visit to the Mount Stromlo Observatory in 1960-61, a major program involved photometry of globular clusters in the Small Magellanic Cloud. Because of the proximity of 47 Tucanae (NGC 104, « = 00h 21^9, 8 = -72° 21', (…

Photoelectric Observations of Magellanic Cloud Cepheids Open
Two-colour photoelectric light-curves have been obtained for 27 cepheids in the Magellanic Clouds. Eight of these have periods shorter than 20 days, and 6 periods longer than 50 days. The shorter-period SMC cepheids are intrinsically about…

Photometry of SN-NGC 4178 (1963) and Eight Low-Luminosity Stars Open
In the course of other work at the 120-inch telescope, one field star, eight stars in three multiple systems, and a supernova were measured in the P, V system of Kron and Mayall.1 The photocell, 1P21 1 of the Lick Observatory, and filters …

Color Excesses from Six-Color Photometry of Supergiant Stars Open
Although the supergiants are very rare objects, their high luminosity permits us to see and investigate considerable numbers of them in spite of the loss of light caused by their great distances and by the presence of absorbing material. S…

Performance Data for Several Infrared-Sensitive Multiplier Phototubes Open
Infrared photometry has been practiced for many years by photoelectric methods ; however, the necessity in the past for employing diode photocells has restricted photometry in the infrared to those observers versed in the highly specialize…

Three-Color Photoelectric Observations of the Intrinsically Faintest Star Known Open
The faint companion of the M3 dwarf BD +4°4048, discovered by G. Van Biesbroeck, has the lowest luminosity of any known star. Interest in this unusual object was recently stimulated by Herbig's success in obtaining three spectrograms of it…
