| Popis: | We carry out a detailed study of the spectral and the timing properties of the stellar-mass black hole candidate XTE J1752-223 during its 2009-10 outburst using RXTE PCA data in the $2.5-25$ keV energy range. Low frequency quasi-periodic oscillations (LFQPOs) are seen in the power density spectrum (PDS). The spectral analysis is done using two types of models: one is the combined disk black body plus power-law model and the other is Transonic flow solution based Two Component Advective Flow (TCAF) model. RXTE PCA was non-operational during 2009 Nov. 16 to 2010 Jan. 18 and thus we study light curve profiles and evolution of hardness ratios using MAXI GSC and Swift BAT data. Based on the evolution of the temporal and the spectral properties of the source during its 2009-10 outburst, we find that the object evolved through the following spectral states: hard, hard-intermediate and soft-intermediate/soft. From the TCAF model fitted spectral analysis, we also estimate the probable mass of the black hole to be in the range of $8.1-11.9$ $M_\odot$, and more precisely, the mass appears to be is $10\pm{1.9}~M_\odot$.
