The Effect of Coronal Radiation on a Residual Inner Disk in the Low/Hard Spectral State of Black Hole X-ray Binary Systems (2011)
Journal Article
Liu, B., Done, C., & Taam, R. (2011). The Effect of Coronal Radiation on a Residual Inner Disk in the Low/Hard Spectral State of Black Hole X-ray Binary Systems. Astrophysical Journal, 726(1), Article 10. https://doi.org/10.1088/0004-637x/726/1/10

Thermal conduction between a cool accretion disk and a hot inner corona can result in either evaporation of the disk or condensation of the hot corona. At low mass accretion rates, evaporation dominates and can completely remove the inner disk. At hi...

A physical interpretation of the variability power spectral components in accreting neutron stars (2010)
Journal Article
Ingram, A., & Done, C. (2010). A physical interpretation of the variability power spectral components in accreting neutron stars. Monthly Notices of the Royal Astronomical Society, 405(4), 2447-2452. https://doi.org/10.1111/j.1365-2966.2010.16614.x

We propose a physical framework for interpreting the characteristic frequencies seen in the broad-band power spectra from black hole and neutron star binaries. We use the truncated disc/hot inner flow geometry, and assume that the hot flow is generic...

X-ray spectral variability in the ultraluminous X-ray source Holmberg IX X-1 (2010)
Journal Article
Vierdayanti, K., Done, C., Roberts, T., & Mineshige, S. (2010). X-ray spectral variability in the ultraluminous X-ray source Holmberg IX X-1. Monthly Notices of the Royal Astronomical Society, 403(3), 1206-1212. https://doi.org/10.1111/j.1365-2966.2009.16210.x

We use XMM–Newton and Swift data to study a spectral variability in the ultraluminous X-ray source (ULX), Holmberg IX X−1. The source luminosity varies by a factor of 3–4, giving rise to corresponding spectral changes which are significant, but subtl...

The ultraluminous state (2009)
Journal Article
Gladstone, J., Roberts, T., & Done, C. (2009). The ultraluminous state. Monthly Notices of the Royal Astronomical Society, 397(4), 1836-1851. https://doi.org/10.1111/j.1365-2966.2009.15123.x

We revisit the question of the nature of ultraluminous X-ray sources (ULXs) through a detailed investigation of their spectral shape, using the highest quality X-ray data available in the XMM–Newton public archives (≳10 000 counts in their EPIC spect... Read More about The ultraluminous state.
