<i>NuSTAR</i> and <i>AstroSat</i> observations of GX 9+1: spectral and temporal studies

We have studied the spectro-temporal properties of neutron star low mass X-ray binary GX 9$+$1 using data from \textit{NuSTAR/FPM} and \textit{AstroSat/SXT} \textit{LAXPC}. The hardness-intensity diagram source showed it to be in soft spectral state during both observations. \textit{NuSTAR} analysis yielded an inclination angle ($\theta$) $=$ 29$\substack{+3\\-4}^{\circ}$ inner disk radius ($R_{in}$) $\leq$ 19.01 km. Assuming that accretion was truncated at Alfv\'en observation, upper limit magnetic dipole moment ($\mu$) field strength ($B$) poles were calculated 1.45$\times$$10^{26}$ G cm$^3$ 2.08$\times$$10^8$ G, respectively (for $k_A$ 1). Flux resolved with \textit{AstroSat} ($F_{disk}$/$F_{total}$ $\sim$0.9) a monotonic increase rate ($\dot{m}$) along banana branch. also presence absorption edges $\sim$1.9 $\sim$2.4 keV, likely due Si XIII S XV, respectively. Temporal \textit{LAXPC-20} 0.02 $-$ 100 Hz range revealed noise components, which could characterized broad Lorentzian components.
