Abstract:
We present a comprehensive spectral-timing study of the black hole
candidate MAXI J1659-152 during its 2010 outburst. We analysed 65
Rossi X-ray timing explorer (RXTE) observations taken along this
period, and computed the fundamental diagrams commonly used to study
black hole transients. We fitted power density and energy spectra and
studied the evolution of the spectral and timing parameters along the
outburst. We discuss the evolution of the variability observed at
different energy bands on the basis of the relative contribution of
the disc and hard components to the energy spectrum of the source.
Description:
We analyse 65 RXTE observations of MAXI J1659-152 performed during
2010 September 28 and November 11.

--------------------------------------------------------------------------------
Note on table1.dat: A model consisting of a power-law, a multi-color
disk-blackbody and a Gaussian emission line with a centroid constrained
between 6.4 and 6.8keV was used.
Note on table2.dat: The noise components were fitted with three Lorentzian
shapes, one zero-centred and other two centred at a few Hz. The QPOs were
fitted with one Lorentzian each.

Note (1): The normalization for the diskbb component is defined as
[(Rin/km)/(D/10kpc)]2cosθ, where Rin is the inner disc
radius (km), D is the distance to the source (kpc) and θ
is the inclination angle of the disc.
