Why the observed black hole candidates do not show spin pulsation | | Abhas Mitra
; | | Date: |
7 Oct 2005 | | Abstract: | It is shown here that the so-called spinning Black Hole Candidates (BHCs) must be spinning HOT Magnetospheric Eternally Collapsing Objects (MECOs). The question would then arise why the spinning BHCs do not reveal their spin pulsation unlike spinning COLD Neutron Stars (NSs). Even for magnetized NSs, there may be no observed spin pulsation if the dipole axis and spin direction are exactly same. However, spinning MECOs do not show spin pulsation because their surface gravitational red shift is extremely high, z ~10^{7-8}. In contrast NSs have z ~ 0.1 -0.3. The time profile of any periodic signal generated on the surface of a spinning MECO gets extremely distorted due to extreme general relativistic frame dragging effect as it traverses through extremely steep gravitational field. However, if any radiation is formed in the MECO magnetosphere sufficiently away from the surface like in the pulsar ``outer slots’’ (which may happen for isolated spinning MECOs), such a radiation might be pulsed one. | | Source: | arXiv, astro-ph/0510205 | | Services: | Forum | Review | PDF | Favorites | |
