  • Cyg X-3

  • Accretion Drived Pulsars

  • Other Sources

    • SS433

    • LMXB

    • AGN

  • Proposals


Cyg x 3

Cyg X-3

  • Discovery of Radiative Recombination Continuum

    • Kawashima and Kitamoto (1996)

    • Liedahl and Paerels (1996)

  • 3,5keV S+15Si+13

  • Measurement of Electron Temperature


Accretion driven pulsars

Accretion Driven Pulsars

Pre-eclipse

  • Vela X-1

    • Nagase et al. (1994)

    • Sako et al.(1999)

      • DEM and wind structure

  • Cen X-3

    • Ebisawa et al.(1996)

  • GX301-2

    • Saraswat et al.(1996)

      • Line emission fromcold gas

Post-Eclipse

Eclipse


Other sources

Other Sources

  • SS433

    • Kotani et al.(1994;19966)

  • 4U1626-67

    • Angelini et al. (1995)

  • AGN MCG-6-30-15

    • Fabian et al. (1994)

  • LMXRB (OVIII lines?)

    • Bautista et al. (1998)


Remaining problems

Remaining Problems

  • Cyg X-3

    • Parameter dependence on the environment

  • Pulsars

    • No direct evidence

  • 4U1626-67

    • Is this an unique source?

  • O & Ne lines in LMXBTrue or Not?


Proposal observation of cyg x 3 in its low state

Proposal: Observation of Cyg X-3 in its Low State

  • Redio Flare: Observed

  • High State : Observed

  • Low State : Not yet

    Scientific Objective

  • Dependence of the photoionization parameters on the environment

    Observation Plan

  • 40 ksec

  • TOO (Alert from RXTE/ASM)

    ASCA’s Benefit

  • Flexibility

  • Cyg X-3 Spectra obtained

    with Ginga/ASM
