Abstract

Galactic short orbital period black hole candidate (BHC) XTE~J1752-223 was discovered on 2009 Oct 21 by the Rossi X-ray Timing Explorer (RXTE). We study the spectral properties of this outburst using transonic flow solution based two component advective flow (TCAF) model. TCAF model fitted spectrum gives an estimation of the physical flow parameters, such as the Keplerian disk rate, sub-Keplerian halo rate, properties of the so-called {\it{Compton cloud}}, other than the mass of the source and normalization ($N$). $N$ is a standardized ratio of emitted to observed photon flux in TCAF which does not include X-ray emission from jets. In the presence of jets, this ratio changes and this deviation is used to obtain the estimation of X-ray contribution from the jets. Nature of the jet is found to be compact during low luminous hard state and discrete or blobby during high luminous intermediate states. We find a correlation between the radio (5.5 GHz) and X-ray ($2.5-25$ keV) fluxes from different components. The radio ($F_R$) and jet X-ray ($F_{ouf}$) fluxes are found to be correlated within the acceptable range of the standard correlation ($0.6$ to $0.7$). A similar correlation indices were reported by our group for three other short orbital period transient BHCs (Swift~J1753.5-0127, MAXI~J1836-194 \& XTE~J1118+480).
