TL;DR: The Einstein X-ray Observatory (HEAO 2) as mentioned in this paper is a fully imaging focusing Xray telescope with an angular resolution of a few arc sec, a field of view of up to one deg, and a sensitivity several hundred times greater than previously available in any Xray astronomy experiment.
Journal ArticleDOI
Results from an extensive Einstein stellar survey.

TL;DR: The preliminary results of the Einstein Observatory stellar X-ray survey are presented in this article, showing that stars in general constitute a pervasive class of low-luminosity galactic Xray sources.
Journal ArticleDOI
X-rays from Eta Carinae and the surrounding nebula.
F. D. Seward,William R. Forman,Riccardo Giacconi,Richard E. Griffiths,F. R. Harnden,Christine Jones,J. P. Pye +6 more
TL;DR: Two X-ray images of the Eta Car nebula were obtained using the imaging detectors of the Einstein Observatory as mentioned in this paper, which showed a region of diffuse x-ray emission with luminosity 10 to the 35th ergs/s.
Journal ArticleDOI
Discovery of a 50 millisecond pulsar in the Large Magellanic Cloud
TL;DR: In this paper, the discovery of a new pulsed X-ray source in the Large Magellanic Cloud (LMC) supernova remnant 0540 - 693 was investigated.
Journal ArticleDOI
Discovery of X-Ray Pulsations from the Compact Central Source in the Supernova Remnant 3C 58
TL;DR: In this paper, high-resolution camera observations of the supernova remnant (SNR) 3C 58 using the High Resolution Camera (HRC) on the Chandra X-Ray Observatory were reported.
