Abstract

Einstein Observatory and EXOSAT X-ray data from 1E0630+178 reveal a ∼50% periodic emission at ≳59s. This confirms the early SAS-II and COS-B findings on 2CG 195+04 atE>50 MeV and provides the temporal signature for the identification of Geminga. The observations, spanning over a decade (1973–1983), also suggest a very high positive $$\dot P$$ which has become still higher in 1979–1983.

Abstract

Data for the soft X-ray source 1E0630+178 are now available from four independent measurements of the Einstein and EXOSAT missions. These are presented and compared in the light of the different characteristics and energy response of the different X-ray imaging detectors used (IPC, LE 1, LE 2). The time variability on medium (∼ hours) time scale is also investigated.
