Thermonuclear Type-I X-ray Bursts and Burst Oscillations from the Eclipsing AMXP Swift J1749.4-2807
A. C. Albayati, P. Bult, D. Altamirano +10
Swift J1749.4-2807 is the only known eclipsing accreting millisecond X-ray pulsar. In this paper, we report on 7 thermonuclear (Type-I) X-ray bursts observed by NICER during its 20…
Hydrogen-triggered X-ray Bursts from SAX J1808.4-3658? The Onset of Nuclear Burning
Sierra Casten, Tod Strohmayer, Peter Bult
We present a study of weak, thermonuclear X-ray bursts from the accreting millisecond X-ray pulsar SAX J1808.4-3658. We focus on a burst observed with the Neutron Star Interior Com…
Detection of millihertz quasi-periodic oscillations in the low-mass X-ray binary 4U 1730--22 with NICER
G. C. Mancuso, D. Altamirano, P. Bult +8
We report the discovery of millihertz quasi-periodic oscillations (mHz QPOs) from the neutron star (NS) low-mass X-ray binary 4U 1730--22 using the Neutron Star Interior Compositio…
Timing analysis of the 2022 outburst of the accreting millisecond X-ray pulsar SAX J1808.43658: hints of an orbital shrinking
Giulia Illiano, Alessandro Papitto, Andrea Sanna +19
We present a pulse timing analysis of NICER observations of the accreting millisecond X-ray pulsar SAX J1808.43658 during the outburst that started on 2022 August 19. Similar to…
The thermonuclear X-ray bursts of 4U 1730-22
Peter Bult, Giulio C. Mancuso, Tod E. Strohmayer +11
We present observations of the historic transient 4U 1730-22 as observed with the Neutron Star Interior Composition Explorer (NICER). After remaining in quiescence since its 1972 d…
MAXI J1957+032: a new accreting millisecond X-ray pulsar in an ultra-compact binary
A. Sanna, P. Bult, M. NG +12
The detection of coherent X-ray pulsations at ~314 Hz (3.2 ms) classifies MAXI J1957+032 as a fast-rotating, accreting neutron star. We present the temporal and spectral analysis p…
