The Pulkovo catalog of 284 positions of Pluto in 1930 - 1994 based on observations from three observatories.

Ryl'Kov, V. P.; Dement'eva, A. A.; Narizhnaja, N. V.

A unique data archive of measurements and reduced positions of Pluto for the period from 1930 to 1994 has been collected from a new reduction of all photographic observations of Pluto obtained by Pulkovo astronomers. All 250 plates taken with the Pulkovo Normal astrograph were remeasured in 1993-1994. These measurements form data files that can be…

The Lyman-α line from the solar wind acceleration region: Results from an eight-moment approximation two-fluid solar wind model

DOI: 10.1029/97GL02583 Bibcode: 1997GeoRL..24.2873O

Olsen, Espen Lyngdal

We investigate neutral hydrogen in an eight-moment, two-fluid, high speed solar wind model. In this model the proton heat flux decreases rapidly in the solar wind acceleration region, and extended coronal heating of the proton gas leads to high coronal proton temperatures and large solar wind flow speeds. The properties of the Lyman-α line from th…

Noci, Giancarlo; Martin, Renato; Maccari, Lisa

We investigate the expected emission from coronal transients in the following spectral lines observable with the Ultraviolet Coronagraph Spectrometer (UVCS) on board SOHO: Hi Lα 1216 Å, Ovi 1032-1037 Å, Nv 1239-1243 Å, Mgx 610-625 Å, Sixii 499-521 Å, and Fexii 1242 Å. We calculate line intensities and profiles for typical CME conditions, and we an…

Using the PPM catalogue as a preliminary reference catalogue, the authors have reduced 17 exposures on 9 plates taken with the 40 cm refractor at Zo-Sè Station of Shanghai Astronomical Observatory in about 30 years. By means of the central overlapping technique and the iterative process, high-precision positions and proper motions of 28 PPM stars,…
