  • A dichotomy between the hard state spectral properties of black hole and neutron star X-ray binaries 
    Burke M.; Gilfanov M.; Sunyaev R. (2017)

    Soraisam M.; Gilfanov M. (2015)
    © 2015 ESO. With the progenitors of type Ia supernovae (SNe Ia) still eluding direct detections, various types of accreting white dwarfs (WDs) have been proposed as prospective candidates. One of the possibilities are WDs ...
