We also found such a positive correlation holds in this persistent neutron star LMXB in a luminosity range spanning about a factor of four. Our results indicate that non-stationary accretion also plays an important role in driving X-ray spectral state transitions in persistent accreting systems ...
together to fuel nuclear fusion. The star's iron core then collapses under its own gravity and reaches temperatures as high as billions of degrees in this process which triggers the star to explode in a supernova. What's left behind at the core can be either a neutron star or a black ...

This explosion leaves behind a “remnant” in the form of a compact object – i.e. aneutron star– and a cloud of gas and dust that is ionized by the energy of the explosion. TheVeil Nebulais a prime example of a Supernova Remnant, as seen in this image captured using a small tele...
The Supergiant X-ray binary Vela X-1 represents one of the best astrophysical sources to investigate the wind environment of a O/B star irradiated by an accreting neutron star. Previous studies and hydrodynamic simulations of the system ... R Amato,V Grinberg,N Hell,... - 《Astronomy & As...
Now you can use, for example, /process/inactivate nCapture to disable neutron capture process in your simulation. And you can use, for example, /process/setVerbose 20 RadioactiveDecay to change the verbosity of the radioactive decay process. Individual optical processes can be toggled by the fo...
Low-mass X-ray binaries (LMXB) serve as natural laboratories, where the predictions of general relativity can be tested in the strong field regime. The primary object of such sources can be a neutron star (NS) or a black hole (BH), and this object captures material from the secondary obj...
The signal GW170817 [4], observed in 2017 by the Advanced LIGO and Advanced Virgo gravitational-wave detectors, is the first from binary neutron star inspiral. The signal GW200105 [5], observed in 2020 by LIGO–Virgo detector network, is the first from two compact binary coalescences. ...
Stars are believed to originate from molecular clouds as well as the dense clouds of gas. A star forms from a big cool mass of gas that arises from the collapse of the dense regions contained in the clouds (Delehanty 1). There are usually some contractions of the gases that form the sta...
