Experimental method of analyzing stress intensity factors and singularity order in rocket motor geometry
… of frozen stress experiments were conducted on surface flaws of varying aspect ratios in pressurized cylinder with star-shaped cutout in order to study the stress intensity factor distribution along the flaw border and to estimate the loss of the inverse square root singularity when the crack …

Proton deceleration near the surface of an accreting neutron star
In binary X-ray sources consisting of a neutron star accreting matter from a companion star, X-radiation is produced by the layer of hot, dense plasma that develops where the matter collides with the neutron star surface. The structure of this layer and the spectrum of the radiation produced there …

Polarized Radiative Transfer in the Magnetospheres and Atmospheres of Neutron Stars
Neutron stars are sources of strongly polarized emission in X-rays or soft gamma-rays due to the presence of strong magnetic fields. Radiation transport of soft X-rays in neutron star surface layers is critical to the determination of the emergent anisotropy of light intensity and polarization …

Type I X-ray bursts as probes of the neutron star accretion flow
Neutron stars in low-mass X-ray binaries frequently exhibit Type I X-ray bursts caused by unstable nuclear burning of accreted matter on the neutron star surface. X-ray bursts offer the opportunity to constrain the neutron star radii and masses and hence the equation of state of one of the densest …

Proton deceleration near the surface on an accreting neutron star
In binary X-ray sources consisting of a neutron star accreting matter from a companion star, Xradiation is produced by the layer of hot, dense plasma that develops where the matter collides with the neutron star surface. The structure of this layer and the spectrum of the radiation produced there …

Accretion- and nuclear-powered phenomena in neutron stars with millisecond spin periods
… the X-ray emission produced by accreting neutron stars with millisecond spin periods can provide important information about the masses M and radii R of neutron stars, thereby yielding uniquely valuable information about the still uncertain properties of cold matter at several times the density of …

Accretion flows and neutron star heating in low-mass X-ray binaries
… and the properties of compact objects. Neutron star (NS) low-mass X-ray binaries (LMXBs) vary in brightness by almost 8 orders of magnitude and are hosts to diverse accretion flows, transporting varying amounts of energy and mass toward the central NS, as well as expelling significant mass from …

Distribuição de pontos fonte para o método das soluções fundamentais: aplicação a problemas de ondas acústicas em domínios exteriores em R3
Neste trabalho pretende-se gerar uma distribuição de pontos fonte adequada para o método das soluções fundamentais (MFS - method of fundamental solutions) que otimize o condici-onamento do sistema linear associado à resolução numérica do problema exterior de difração de um campo acústico incidente …
