Parameters of Six Selected Galactic Potential Models

open access: yesOpen Astronomy, 2017
This paper is devoted to the refinement of the parameters of the six three-component (bulge, disk, halo) axisymmetric Galactic gravitational potential models on the basis of modern data on circular velocities of Galactic objects located at distances up ...

Phase spirals induced by the gas warp

open access: yesAstronomy & Astrophysics
Context. The discovery of the phase space-spirals in the Solar neighborhood in Gaia Data Release 2 has prompted various attempts to understand their origin. A source of bending waves that has been neglected as a cause of the phase spiral is irregular gas

Mass Distribution and Gravitational Potential of the Milky Way

open access: yesOpen Astronomy, 2017
Models of mass distribution in the Milky Way are discussed where those yielding the potential analytically are preferred. It is noted that there are three main contributors to the Milky Way potential: bulge, disc and dark halo.

On the application of a particular form of the gravitational potential [PDF]

open access: yesSerbian Astronomical Journal, 2003
A formula, already existing in the literature, describing the gravitational potential of a spherically symmetric stellar system is analyzed. Some interesting cases of comparison with empirical formulae are presented. A good agreement is found.

Natural Frequencies of Levodopa‐Induced Dyskinesia in Parkinson's Disease

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objectives Abnormal involuntary movements, known as dyskinesias, are common complications of levodopa treatment in patients with Parkinson's disease and can significantly impair quality of life. The underlying pathophysiology remains unclear, and current therapeutic options are limited.

Microstructural Evolution and Vacancy Defect Formation in Mn–Mo–Ni RPV Steel Under Low Cycle Fatigue: Insights From EBSD and PALS

open access: yesAdvanced Engineering Materials, EarlyView.
Low‐cycle fatigue damage in Mn–Mo–Ni reactor pressure vessel steel is examined using a combined electron backscatter diffraction and positron annihilation lifetime spectroscopy approach. The study correlates texture evolution, dislocation substructure development, and vacancy‐type defect formation across uniform, necked, and fracture regions, providing

Identifying substructure associations in the Milky Way halo using chemo-kinematic tagging

open access: yesAstronomy & Astrophysics
Context. The Milky Way halo has been built-up over cosmic time through the accretion and dissolution of star clusters and dwarf galaxies as well as through their complex interactions with the Galactic disc.
