Sensitivity Study of Nuclear Reactions Influencing Photospheric Radius Expansion X-Ray Bursts [PDF]
EPJ Web of Conferences, 2022 Up to now, more than 62 of the 115 X-ray sources of low-mass-X-ray binaries have been identified as photospheric radius expansion (PRE) bursters [1]. Galloway and collaborators expect more PRE bursters in their near future analysis [2].

THE NUMERICAL THREE-DIMENSIONAL HYDRODYNAMIC SIMULATION OF THE γ-RAY BURSTERS AND X-RAY BURSTERS
Odessa Astronomical Publications, 2013 An radiative wind accretion on to the compact object in a detached close binary system (CBS) where one of the components is a supergiant with radiation stellar wind that blows from its surface, and another component is a compact object (black hole or ...

Constraints on Neutron Star Structure from the Clocked X-Ray Burster 1RXS J180408.9−342058
The Astrophysical Journal, 2023 Type I X-ray bursts are rapid-brightening transient phenomena on the surfaces of accreting neutron stars (NSs). Some X-ray bursts, called clocked bursters, exhibit regular behavior with similar light-curve profiles in their burst sequences.

A Comprehensive Study of Type I (Thermonuclear) Bursts in the New Transient SRGA J144459.2–604207
The Astrophysical JournalWe report an analysis of Insight-HXMT observations of the newly discovered accreting millisecond pulsar SRGA J144459.2–604207. During the outburst, detected in 2024 February by SRG/ART-XC, the broadband persistent spectrum was well fitted by an absorbed ...

Thermonuclear Superburst of MAXI J1752−457 Observed with NinjaSat and MAXI
The Astrophysical Journal LettersAn uncatalogued bright X-ray transient was detected with MAXI on 2024 November 9, named MAXI J1752−457. The NinjaSat X-ray observatory promptly observed the source from November 10 to 18, while the small angular separation from the Sun hampered follow-up

The Astrophysical JournalWe performed astrophysics model calculations with updated nuclear data to identify a possible bypass of the ^64 Ge waiting point, a defining feature of the rapid proton capture (rp) process that powers type I X-ray bursts on accreting neutron stars.

Quenching and Recovery of Persistent X-Ray Emission during a Superburst in 4U 1820–30
The Astrophysical JournalWe report the superburst from 4U 1820–30 in 2021 observed by the Monitor of All-sky X-ray Image and Neutron star Interior Composition Explorer (NICER).
