Modeling X-ray reflection spectra from returning radiation: application to 4U 163047
Kostas Kourmpetis, Shafqat Riaz, Honghui Liu +6
Returning radiation is thought to play a key role in disk illumination of black hole X-ray binaries in the high-soft state, yet it has not been fully incorporated into XSPEC reflec…

Confronting recent light compact star observations with color-flavor locked quark matter
K. Kourmpetis, P. Laskos-Patkos, Ch. C. Moustakidis
Recent analyses on the properties of the central compact object in the HESS J1731-347 remnant and the PSR J1231-1411 pulsar indicated that these two compact objects are characteriz…

Constraints on color-flavor locked quark matter in view of the HESS J1731-347 measurement
K. Kourmpetis, P. Laskos-Patkos, Ch. C. Moustakidis
Astrophysical observations play a crucial role in understanding the processes within compact stars. A recent study measured the central object in the HESS J1731-347 supernova remna…
