Presentation Transcript

  1. Photoionized Plasmawith ASCA • Cyg X-3 • Accretion Drived Pulsars • Other Sources • ＳＳ４３３ • LMXB • AGN • Proposals

  2. Cyg X-3 • Discovery of Radiative Recombination Continuum • Kawashima and Kitamoto (1996) • Liedahl and Paerels (1996) • 3,5keV S+15 Si+13 • Measurement of Electron Temperature

  3. 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

  4. 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)

  5. 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 LMXB True or Not?

  6. 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
