If there exists the quark star of maximum mass ∼ 0.7M⊙ as suggested by recent Chandra observations, we show that the general relativistic collapse of a neutron star of mass greater than the maximum mass of the neutron star with angular momentum parameter q ≡ cJ/GM > 1 may lead to such a strange star. Here J and M are the angular momentum and the gravitational mass of the neutron star, respectiv...

We compute the synthetic 2-100 keV spectrum of an actively star forming galaxy. To this aim we use a luminosity function of point sources appropriate for starbursts (based on Chandra data), as well as the types of stellar sources and their corresponding spectra. Our estimates indicate that a Compton spectral component resulting from scattering of SN-accelerated electrons by ambient FIR and CMB ...
