Sharp Periodic Flares and Long-Term Variability in the High-Mass X-ray Binary XTE J1829-098 from RXTE PCA, Swift BAT and MAXI Observations

Robin H. D. Corbet, Ralf Ballhausen, Peter A. Becker +20

XTE J1829-098 is a transient X-ray pulsar with a period of ~7.8 s. It is a candidate Be star system, although the evidence for this is not yet definitive. We investigated the twent…

Spectral evolution of RX J0440.9+4431 during the 2022-2023 giant outburst observed with Insight-HXMT

P. P. Li, Peter A. Becker, L. Tao

In 2022-2023, the X-ray pulsar RX J0440.9+4431 underwent a Type II giant outburst, reaching a peak luminosity L_x ~ 4*10^{37} erg/s. In this work, we utilize Insight-HXMT data to a…

The giant outburst of EXO 2030+375 II: Broadband spectroscopy and evolution

R. Ballhausen, P. Thalhammer, P. Pradhan +13

In 2021, the high-mass X-ray binary EXO 2030+375 underwent a giant X-ray outburst, the first since 2006, that reached a peak flux of (3-50\,keV). The go…

The giant outburst of EXO 2030+375 I: Spectral and pulse profile evolution

P. Thalhammer, R. Ballhausen, E. Sokolova-Lapa +12

The Be X-ray binary EXO 2030+375 went through its third recorded giant outburst from June 2021 to early 2022. We present the results of both spectral and timing analysis based on N…

Theoretical Analysis of the RX J0209.6-7427 X-ray Spectrum During Giant Outburst

Brent F. West, Peter A. Becker, Georgios Vasilopoulos

We model the spectral formation occurring in the binary X-ray pulsar RX~J0209.6-7427 during the 2019 super-Eddington outburst. Using a theoretical model previously developed by the…
