CONNECTION OF ADDITIONAL PULSAR EMISSION COMPONENTS IN THE CRAB WITH THE RESONANCE REFLECTION FROM A NEUTRON STAR [PDF]

open access: yesRadio Physics and Radio Astronomy, 2018
Purpose: The subject of the paper is discussion of reflected radiation from the neutron star surface. Such radiation, as was shown earlier by S. V. Trofymenko and one of the authors, occurs when reflects the radiation of relativistic positrons flying ...

I–V and C–V characteristics and interface electron states of Al2O3/AlGaN/GaN structures [PDF]

open access: yesModern Electronic Materials
This paper analyzes properties of the dielectric/AlGaN/GaN system with an ALD Al2O3 film as a dielectric. It was investigated how the current flow process in the system changes due to the deposition of films with different thicknesses; at what bias ...

Finding the Ionospheric Fluctuations Reflection in the Pulsar Signals’ Characteristics Observed with LOFAR

open access: yesSensors, 2020
Pulsars’ signals reaching the atmosphere can be considered being stable under certain assumptions. In such a case the ionosphere remains the main factor distorting signal from the extraterrestrial sources, particularly if we observe them at long radio ...

Pulsars and gravity [PDF]

open access: yesInternational Journal of Modern Physics D, 2006
Pulsars are wonderful gravitational probes. Their tiny size and stellar mass give their rotation periods a stability comparable to that of atomic frequency standards. This is especially true of the rapidly rotating "millisecond pulsars" (MSPs). Many of these rapidly rotating pulsars are in orbit with another star, allowing pulsar timing to probe ...
