Presentation Transcript

  1. Poster Presentation at XXVI GA IAU, 14-25 August, 2006, JD02-16 External Electromagnetic Fields of Slowly Rotating Relativistic Magnetized NUT Stars Presenter: Bobomurat Ahmedov, Uzbekistan AS, Tashkent E-mail: ahmedov@astrin.uzsci.net Co-author: Avas Khugaev

  2. Plan of talk • Basic assumptions and approach • Electromagnetic Fields of Slowly Rotating Axial Symmetric Magnetized NUT Star • Conclusion

  3. GR effects are important for compact objects • Immense difficulty of simultaneously solving the Maxwell eqs and the highly nonlinear Einstein eqs

  4. APPROACH EMF are considered in a given background geometry R - g R/2 = T T = T(matter) + T(em)¼ T(matter) (em) c2¼ B2/8 )(em)¼ 103 g/cm3 if B s 1012 G (em)¿(matter)¼ 1014 g/cm3 consequently T(em)¿ T(matter) Slow rotation approximation: comparing the neglected terms with the lower order one gives ratios R32/GM < 10% even for fastest rotating stars (PSR J1748-2446ad & PSR 1937+214)

  5. METRIC OF SLOWLY ROTATING NUT STAR

  6. (r) ´ 2aM/r3 ZAMO OBSERVER:

  7. Monopolar configuration for MF

  8. DIPOLAR MAGNETIC FIELD

  9. CONCLUSION • E/M Fields of Rotating Magnetized NUT stars in General Relativity: GR Effects Resulting from Dragging of Inertial Frames Monopolar Part and NUT parameter are Very Important for EF For MF only mass of star plays a role
