Neutron Star Model Atmospheres [PDF]

open access: yesAIP Conference Proceedings, 2009
Determination of neutron star (NS) parameters is an important astrophysical problem. The stellar radius depends on the mass and the equation of state (EOS) in the NS core, which is not well known. Therefore, with masses and radii inferred from observations we are able to select between various theories for the EOS.

Experimental Study on Real-time Measurement of Atmospheric-neutron Induced Single Event Effect Based on High-altitude Area

open access: yesYuanzineng kexue jishu, 2022
Based on the test site at the Qinghai Tibet Plateau with an altitude of 4 300 m, atmospheric neutron single event effects of a 65 nm high speed large area static random access memory (SRAM) array were measured in real time.

Observing the neutron component during thunderstorm activity at a mountain CR station

open access: yesSolar-Terrestrial Physics, 2019
During three summer months in 2015, the Cosmic Ray (CR) station Irkutsk-3000, located at 3000 m above sea level, measured the CR neutron component intensity with the 6NM64 neutron monitor, as well as the atmospheric electric field strength and the level ...

Sensitivity improvements via enhanced neutron detection in SK-Gd atmospheric neutrino oscillation analysis

open access: yes, 2022
With the loading of Gadolinium in the Super-Kamiokande detector, the overall detection efficiency of neutrons from neutrino-nucleus interaction has greatly increased. Based on semi-tuned atmospheric neutrino event simulation, we estimate how the improved

A HYDROGENIC MOLECULAR ATMOSPHERE OF A NEUTRON STAR

open access: yesModern Physics Letters A, 2004
A model of a hydrogenic content of atmosphere of the isolated neutron star 1E1207.4-5209 is proposed. It is based on the assumption that the main component in the atmosphere is the exotic molecular ion [Formula: see text] and that there exists a magnetic field in the range of (4±2)×1014 G .

Unfolding the Neutron Flux Spectrum on the Surface of Mars Using the MSL‐RAD and Odyssey‐HEND Data

open access: yesSpace Weather, 2023
Understanding the long‐term radiation environment at the surface of Mars allows us to estimate the exposure for future robotic and crewed missions. Typically, the radiation environment includes charged particles (i.e., protons and heavier ions) and ...
