AstroSat view of GRS 1915+105 during the Soft State: Detection of HFQPOs and estimation of Mass and Spin

We report the results of AstroSat observations of GRS 1915\(+\)105 obtained using 100 ks guaranteed-time (GT) during the soft state. The Color-Color Diagram (CCD) indicates a variability class of \(\delta\) with the detection of High Frequency QPO (HFQPO) in the power density spectra (PDS). The HFQP...
