Abstract :

We report discovery of Quasi Periodic Oscillations (QPOs) frequencies 25±2.1 mHz, 4±1.3 mHz, 15±1.8 mHz for different outburst of Low mass X–ray source GX340+0 on dated April 1997, November 1998, August 2000 respectively. The flux below the surface layer produced due to conduction of energy during X–ray bursts pours slowly upward and hence generates stable burning on the surface of compact object (neutron star). The mHz QPO only occurs if burning fuel rate (dm/dt) = (dm/dt) = (dm/dt)EDD. These types of mHz QPOs appear in weak magnetized X–ray source because strong magnetic field compresses conduction of heat flux below the core of neutron star
