High-resolution X-ray spectroscopy of Cen X-3 with XMM-Newton

J. J. Rodes-Roca, J. M. Torrejón, G. Sanjurjo-Ferrín +1

The spectral analysis of two XMM-Newton observations of the high-mass X-ray binary system Cen X-3 is presented. In particular, it is focused on the eclipse and out-of-eclipse spect…

Cyclical accretion regime change in the slow X-ray pulsar 4U 0114+65 observed with Chandra

Graciela Sanjurjo-Ferrín, Jose Miguel Torrejón, Konstantin Postnov +5

4U 0114+65 is a high-mass X-ray binary system formed by the luminous supergiant B1Ia, known as V{*} V662 Cas, and one of the slowest rotating neutron stars (NS) with a spin period…

A Time-Dependent Spectral Analysis of Cassiopeiae

Sean J. Gunderson, David P. Huenemoerder, José M. Torrejón +7

We investigated the temporal and spectral features of Cassiopeiae's X-ray emission within the context of the white dwarf accretion hypothesis. We find that the variabilities p…

GX 301-2 pre-periastron and apastron flares with MAXI

Á. Torregrosa, J. J. Rodes-Roca, J. M. Torrejón +4

The bright high-mass X-ray binary GX 301-2 exhibits two periodic flare episodes along its orbit which are produced when the neutron star is close to the apastron and periastron pas…
