The evolutionary history of ultra-compact accreting binaries. II. HST spectroscopy of two eclipsing AM CVn stars
W. Yu, A. F. Pala, T. Kupfer +50
AM CVn stars are ultra-compact binaries in which a white dwarf (WD) accretes helium-rich material from a hydrogen-deficient donor. They are promising mHz gravitational-wave sources…
MeerKAT radio detection of the Galactic black hole candidate Swift J1842.5-1124 during its 2020 outburst
X. Zhang, W. Yu, S. E. Motta +4
Swift J1842.51124 is a transient Galactic black hole X-ray binary candidate, which underwent a new outburst in May 2020. We performed multi-epoch MeerKAT radio observations unde…
A repeating fast radio burst associated with a persistent radio source
C. -H. Niu, K. Aggarwal, D. Li +32
The dispersive sweep of fast radio bursts (FRBs) has been used to probe the ionized baryon content of the intergalactic medium, which is assumed to dominate the total extragalactic…
Sources of The Slow Solar wind During the Solar Cycle 23/24 Minimum
E. K. J. Kilpua, M. S. Madjarska, N. Karna +4
We investigate the characteristics and the sources of the slow (< 450 km/s) solar wind during the four years (2006-2009) of low solar activity between Solar Cycles 23 and 24. We us…
Using XMM-Newton to study the energy dependent variability of H 1743-322 during its 2014 outburst
H. Stiele, W. Yu
Black hole transients during bright outbursts show distinct changes of their spectral and variability properties as they evolve during an outburst, that are interpreted as evidence…
The LOFT perspective on neutron star thermonuclear bursts
J. J. M. in 't Zand, D. Altamirano, D. R. Ballantyne +31
This is a White Paper in support of the mission concept of the Large Observatory for X-ray Timing (LOFT), proposed as a medium-sized ESA mission. We discuss the potential of LOFT f…
Orbital Period and Outburst Luminosity of Transient Low Mass X-ray Binaries
Y. X. Wu, W. Yu, T. P. Li +2
In this paper we investigate the relation between the maximal luminosity of X-ray outburst and the orbital period in transient low mass X-ray binaries (or soft X-ray transients) ob…
On the Relation of Hard X-ray Peak Flux and Outburst Waiting Time in the Black Hole Transient GX 339-4
Y. X. Wu, W. Yu, Z. Yan +2
Aims. In this work we re-investigated the empirical relation between the hard X-ray peak flux and the outburst waiting time found previously in the black hole transient GX 339-4. W…
The Cross-Spectra of Cir X-1: Evolution of Time Lags
J. L. Qu, W. Yu, T. P. Li
Earlier work showed that the track in the X-ray hardness-intensity diagram of Cir X-1 corresponds to a Z track in its color-color diagram. In this paper, we study the cross spectru…
Spectral State Transitions in Aql X-1: Evidence for `Propeller' Effects
S. N. Zhang, W. Yu, W. Zhang
Aql X-1 is a soft X-ray transient source and emits type I X-ray bursts. A spectral state transition was observed with RXTE during its outburst decay in February and March 1997. Its…
