Truncation of the Accretion Disk at One Third of the Eddington Limit in the Neutron Star Low-Mass X-ray Binary Aquila X-1

Renee M. Ludlam, Jon M. Miller, Nathalie Degenaar +4

We perform a reflection study on a new observation of the neutron star low-mass X-ray binary Aquila X-1 taken with NuSTAR during the August 2016 outburst and compare with the July…

Evidence of a non-conservative mass transfer for XTE J0929-314

A. Marino, T. Di Salvo, A. F. Gambino +5

Context. In 1998 the first accreting millisecond pulsar, SAX J1808.4-3658, was discovered and to date 18 systems showing coherent, high frequency (> 100 Hz) pulsations in low mass…

Relation between the properties of the kilohertz quasi-periodic oscillations and spectral parameters in 4U 163653

Evandro M. Ribeiro, Mariano Méndez, Guobao Zhang +1

We investigate the relation between the parameters of the energy spectrum and the frequency and amplitude of the kilohertz quasi-periodic oscillations (kHz QPOs) in the low-mass X-…

Swift observations of V404 Cyg during the 2015 outburst: X-ray outflows from super-Eddington accretion

S. E. Motta, J. J. E. Kajava, C. Sánchez-Fernández +11

The black-hole binary V404 Cyg entered the outburst phase in June 2015 after 26 years of X-ray quiescence, and with its behaviour broke the outburst evolution pattern typical of mo…

On the timing properties of SAX J1808.4-3658 during its 2015 outburst

A. Sanna, T. Di Salvo, L. Burderi +7

We present a timing analysis of the 2015 outburst of the accreting millisecond X-ray pulsar SAX J1808.4-3658, using non-simultaneous XMM-Newton and NuStar observations. We estimate…

Imaging of SNR IC443 and W44 with the Sardinia Radio Telescope at 1.5 GHz and 7 GHz

E. Egron, A. Pellizzoni, M. N. Iacolina +33

Observations of supernova remnants (SNRs) are a powerful tool for investigating the later stages of stellar evolution, the properties of the ambient interstellar medium, and the ph…

The reflection spectrum of the low-mass X-ray binary 4U 1636-53

Yanan Wang, Mariano Mendez, Andrea Sanna +2

We present 3-79 keV NuSTAR observations of the neutron star low-mass X-ray binary 4U 1636-53 in the soft, transitional and hard state. The spectra display a broad emission line at…

A re-analysis of the NuSTAR and XMM-Newton broad-band spectrum of Ser~X-1

M. Matranga, T. Di Salvo, R. Iaria +4

Context: Ser X-1 is a well studied LMXB which clearly shows a broad iron line. Recently, Miller et al. (2103) have presented broad-band, high quality NuSTAR data of SerX-1.Using re…
