Spectro-polarimetric view of bright atoll source GX 9+9 using<i>IXPE</i>and<i>AstroSat</i>

We have carried out the first spectro-polarimetric study of bright NS-LMXB GX 9+9 using IXPE and AstroSat observations. report a significant detection polarization $1.7\pm 0.4\%$ over $2-8$ keV energy band, with angle $63^{\circ}\pm 7^{\circ}$. The is found to be energy-dependent, $3\sigma$ degree consistent null in $2-4$ keV, $3.2\%$ $4-8$ keV. Typical spectra seen NS-LMXBs, we find that combination soft thermal emission from accretion disc Comptonized component optically thick corona produces good fit spectra. also attempt infer individual these components, obtain upper limit $\sim 11\%$ on component, constrain 3\%$. comment possible geometry system based our results.
