Accreting Neutron star (NS) X-ray binaries are some of the unique laboratories in the universe as they have one of the strongest gravity regimes and interaction of high-temperature matter. X-ray observations of these sources provide insights into the emission components and constrain the physical properties of compact objects due to the proximity of the emission region to the compact object. In this seminar, I will discuss an interesting NS X-ray binary GX 340+0 and how the X-ray and radio observations of the source can be interpreted to understand the dynamics of such systems. The source shows a peculiar Z-track on its hardness-intensity diagram which we probe with our observations. We have done an extensive campaign of the source to study the spectral, timing, and polarimetric properties of GX 340+0 in X-ray and radio wavelengths, revealing many interesting properties of the source. I will also discuss how polarimetric observations are essential to identify the emission components and reject geometrical configurations in such systems.
