Nucleosynthesis in type I X-ray bursts [PDF]
Progress in Particle and Nuclear Physics, 2013 Type I X-ray bursts are thermonuclear explosions that occur in the envelopes of accreting neutron stars. Detailed observations of these phenomena have prompted numerous studies in theoretical astrophysics and experimental nuclear physics since their discovery over 35 years ago.

Investigating Time Variability of X-Ray Absorption in Swift GRBs
The Astrophysical Journal, 2023 The existence of excess absorption in the X-ray spectra of GRBs is well known, but the primary location of the absorbing material is still uncertain. To gain more knowledge about this, we have performed a time-resolved analysis of the X-ray spectra of ...

Supercollapsars and their X-ray bursts [PDF]
Monthly Notices of the Royal Astronomical Society: Letters, 2010 Abstract The very first stars in the Universe can be very massive, up to 103 M⊙. If born in large numbers, such massive stars can have a strong impact on the subsequent star formation, producing strong ionizing radiation and contaminating the primordial gas with heavy elements.

X-Ray Bursts of Nuclear Origin [PDF]
Highlights of Astronomy, 1977 The fate of nuclear energy carried by matter accreted onto a neutron star was considered e.g. by Rosenbluth et al. (1973). They examined pycnonuclear reactions on an originally cold star, and found that the whole star is thereby heated up to 106−107 °K. The thermonuclear reactions that can be ignited then, have been studied by Hansen and Van Horn (1975)

Detection of X-Ray Bursts in Astronomical Time Series: The Burst of GRO J1744-28 as an Example
The Astrophysical Journal, 2023 To automatically, accurately, and quickly detect local changes in time-series data continuously emitted by X-ray sources, an autoencoder-based unsupervised learning anomaly detection method is proposed.

Solar Physics, 1985 The major results from SMM are presented as they relate to our understanding of the energy release and particle transportation processes that lead to the high-energy X-ray aspects of solar flares. Evidence is reviewed for a 152–158 day periodicity in various aspects of solar activity including the rate of occurrence of hard X-ray and gamma-ray flares ...

Different types of X-ray bursts from GRS 1915+105 and their origin [PDF]
, 1999 We report the X-ray observations of the Galactic X-ray transient source GRS 1915+105 with the PPCs of the Indian X-ray Astronomy Experiment(IXAE) onboard the Indian satellite IRS-P3 during 1997 June - August, which have revealed the presence of four ...
