Blind Line Search System: BLiSS
Luis Abalo, Graciela Sanjurjo-FerrÃn, Jessica Planelles-Villalva +2
The increasing sensitivity and spectral resolution of current and forthcoming X-ray observatories, including \textit{XRISM} and \textit{NewAthena}, are expected to reveal increasin…
High-resolution X-ray spectroscopy of Cen X-3 with XMM-Newton
J. J. Rodes-Roca, J. M. Torrejón, G. Sanjurjo-FerrÃn +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-FerrÃn, 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
Ã. 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…
