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 pr…
Revealing the state transition of Cen X-3 at high spectral resolution with Chandra
Graciela Sanjurjo-Ferrín, Jose Miguel Torrejón, Lida Oskinova +4
Cen X-3 is a compact, high-mass X-ray binary (HMXRB), likely powered by Roche lobe overflow. We present a phase-resolved X-ray spectral and timing analysis of a target of opportuni…
The clumpy absorber in the high-mass X-ray binary Vela X-1
V. Grinberg, N. Hell, I. El Mellah +13
Bright and eclipsing, the high-mass X-ray binary Vela X-1 offers a unique opportunity to study accretion onto a neutron star from clumpy winds of O/B stars and to disentangle the c…
Chandra and Suzaku observations of the Be/X-ray star HD110432
Jose M. Torrejon, Norbert S. Schulz, Michael A. Nowak
We present an analysis of a pointed 141 ks Chandra high resolution transmission gratings observation of the Be X-ray emitting star HD110432, a prominent member of the gamma Cas ana…
Dynamical Ne K Edge and Line Variations in the X-Ray Spectrum of the Ultra-compact Binary 4U 0614+091
Norbert S. Schulz, Michael P. Nowak, Deepto Chakrabarty +1
We observed the ultra-compact binary candidate 4U 0614+091 for a total of 200 ksec with the high-energy transmission gratings onboard the \chandra X-ray Observatory. The source is…
