"Giotto" - the second comet.

Bibcode: 1993ZemVs...4...55S

Schwehm, G. H.

The author reports on the "Giotto Extended Mission" to comet Grigg-Skjellerup. The investigations of Giotto have provided new data concerning the interaction of solar wind with a non-magnetized body in space.

Calibration of HST narrow band filters using the Orion Nebula.

Bibcode: 1993RMxAA..27..153H

Hu, Xihai

HST images in three emission line filters: Hα, [O III] and [N II] have been calibrated. The CCD sensitivity was determined by comparing regions within HST frames with the corresponding surface brightness determined from ground based Orion Nebula observations. Corrections for continuum within each filter were made. It was necessary to correct the […

Analysis of COS-B and HEAO-B satellite data of the pulsar Geminga

Bibcode: 1993AcApS..12..389M

Song, Li-Ming; Wu, Mei; Ma, Yu-Qian +4 more

Timing and spectral analysis of COS-B and HEAO-B satellite data of the pulsar Geminga are presented. The results confirm that Geminga is a pulsar with a strong gamma emission and a weak X-ray emission. A phase histogram of Geminga in different energy ranges from a summation of four COS-B observations is given.

X-ray studies of Be/X-ray binaries.

Bibcode: 1993BASI...21..359S

Saraswat, Priyamvada

In this thesis a study of some X-ray binaries in which a Be star is a primary has been undertaken in an effort to understand the nature of X-ray emission from these sources. The work attempts to answer questions regarding the structure of the circumstellar disk and its evolution with time. The thesis consists of two parts. The first part is devote…

Periodicities in the IUE Particle Radiation Data

DOI: 10.1086/133203 Bibcode: 1993PASP..105..603A

Arquilla, Richard

The magnetospheric charged particle flux measured serendipitously by the IUE satellite during perigee passages from February 1978 to February 1989 has been searched for periodicities using Fourier transform and correlation techniques. The analysis uncovers persistent modulations of the particle flux with periods of 28 to 33 days and 15 to 17 days.…
