Death Line For Radio Pulsars In Braneworlds, Djavlanbek Rayimbaev, Satimbay Palvanov, Maksud Umaraliyev, Malika Khudoyberdiyeva
Bulletin of National University of Uzbekistan: Mathematics and Natural Sciences
We investigate the effects of braneworlds on energetic processes in plasma. magnetosphere of neutron stars. Obtained that the presence of brane charge causes an increase in the size of the polar cap region. It has shown that the polar capsize of neutron stars with larger rotation period and compactness parameter is also larger. We have studied deathline of radio pulsar in braneworld. Obtained that the deathline shifted down and the pulsars which lying on the deathline become visible in radio band. Moreover, we have extended particle acceleration in polar cap of neutron stars in the presence of the brane charge, …

Bulletin of National University of Uzbekistan: Mathematics and Natural Sciences
We investigate circular motion of charged and neutral particles around non-rotating black hole immersed in an external asymptotically uniform magnetic field. The effects of braneworlds on innermost circular stable orbits have been considered. Shown that innermost circular orbits (ISCO) decreases in decreasence of both brane charge and particle charge. Moreover, we have investigated energy extraction from black holes in braneworld through collision of two particles. Obtained that the presence of the brane charge parameter causes to decrease of the value of center of mass energy of colliding two charged particles, it means the brane charge acts as an additional gravity.
