Estimating the Spins of Stellar-Mass Black Holes by Fitting Their Continuum Spectra
Ramesh Narayan, Jeffrey E. McClintock, Rebecca Shafee
We have used the Novikov-Thorne thin disk model to fit the continuum X-ray spectra of three transient black hole X-ray binaries in the thermal state. From the fits we estimate the…
Estimating the Spins of Stellar-Mass Black Holes
Jeffrey E. McClintock, Ramesh Narayan, Rebecca Shafee
We describe a program that we have embarked on to estimate the spins of stellar-mass black holes in X-ray binaries. We fit the continuum X-ray spectrum of the radiation from the ac…
Viscous Torque and Dissipation in the Inner Region of a Thin Accretion Disk: Implications for Measuring Black Hole Spin
Rebecca Shafee, Ramesh Narayan, Jeffrey E. McClintock
We consider a simple Newtonian model of a steady accretion disk around a black hole. The model is based on height-integrated hydrodynamic equations, alpha-viscosity, and a pseudo-N…
