Insight-HXMT observations of Swift J0243.6+6124: the evolution of RMS pulse fractions at super-Eddington luminosity
P. J. Wang, L. D. Kong, S. Zhang +116
Based on Insight-HXMT data, we report on the pulse fraction evolution during the 2017-2018 outburst of the newly discovered first Galactic ultraluminous X-ray source (ULX) Swift J0…
X-ray reprocessing in accreting pulsar GX 301-2 observed with Insight-HXMT
L. Ji, V. Doroshenko, V. Suleimanov +100
We investigate the absorption and emission features in observations of GX 301-2 detected with Insight-HXMT/LE in 2017-2019. At different orbital phases, we found prominent Fe Kalph…
Insight-HXMT observations of a possible fast transition from jet to wind dominated state during a huge flare of GRS~1915+105
L. D. Kong, S. Zhang, Y. P. Chen +92
We present the analysis of the brightest flare that was recorded in the \emph{Insight}-HMXT data set, in a broad energy range (2200 keV) from the microquasar GRS~1915+105 during…
Physical origin of the nonphysical spin evolution of MAXI J1820+070
J. Guan, L. Tao, J. L. Qu +91
We report on the Insight-HXMT observations of the new black hole X-ray binary MAXI J1820+070 during its 2018 outburst. Detailed spectral analysis via the continuum fitting method s…
Saturation of Energy Levels of the Hydrogen Atom in Strong Magnetic Field
T. C. Adorno, D. M. Gitman, A. E. Shabad
We demonstrate that the finiteness of the limiting values of the lower energy levels of a hydrogen atom under an unrestricted growth of the magnetic field, into which this atom is…
The study of two quasi-degenerate heavy sterile neutrinos in rare meson decays
Jiabao Zhang, Tianhong Wang, Geng Li +2
In this work, we study the lepton-number-violating processes of and mesons. Two quasi-degenerate sterile neutrinos are assumed to induce such processes. Different w…
