The Optimization of Transfer Trajectory for Small Amplitude Halo Orbits
Measurement + Control, 2008 Since the halo orbits in the vicinity of the collinear libration points have a strong hyperbolic character, it is possible to use their stable manifold for the transfer from the Earth.

The orbital structure of galactic halos
The Astrophysical Journal, 1992 Earlier numerical experiments have shown that the orbital structure in the halo of a triaxial logarithmic potential differs significantly from that in the main body of the potential; the usual box orbits are replaced by boxlets originating in higher resonances. Now we have further investigated this phenomenon, with the following results.

Elastic electron scattering from 17Ne and 27P exotic nuclei
Iraqi Journal of Physics, 2019 The ground state proton, neutron and matter densities and corresponding root mean square radii of unstable proton-rich 17Ne and 27P exotic nuclei are studied via the framework of the twofrequency shell model.

Transverse halo orbits about Mars? [PDF]
Geophysical Research Letters, 2003 We predict a new family of charged dust rings about Mars, transverse to the ecliptic plane. These orbits are stable to the perturbations of planetary oblateness, Mars' orbital motion, and the solar wind. Lifetimes of individual orbits are limited primarily by the Lorentz force and Poynting‐Robertson drag, and may exceed 1000 years.

Stability of Circular Orbits Around Kerr Black Holes Immersed in a Dehnen-Type Dark Matter Halo
UniverseWe investigate the dynamical stability of circular orbits around a Kerr black hole embedded in a Dehnen-type dark matter halo. The effective spacetime metric of the combined system is constructed using the Newman–Janis algorithm, and the effective ...

Particle motion and QPOs around Euler-Heisenberg black hole immersed in cold dark matter halo
Nuclear Physics BWe explore the motion of particles in the vicinity of an Euler-Heisenberg black hole immersed in a cold dark matter halo, focusing on how the black hole parameters influence particle dynamics. This black hole solution is characterized by five parameters,

Pediatric Blood &Cancer, EarlyView.ABSTRACT Background Survivors of pediatric brain tumors (PBTs) can experience long‐term social difficulties, impacting quality of life. Beyond medical and environmental factors, family psychosocial risk may play a role in social outcomes by shaping the caregiving environment and may provide intervention options.

Pediatric Blood &Cancer, EarlyView.ABSTRACT Pediatric intramedullary low‐grade gliomas (PIMLGGs) are rare neoplasms that present unique clinical and management challenges. Although surgery remains the primary tool for tissue diagnosis and decompression, complete gross‐total resection is frequently unfeasible due to the infiltrative nature of these lesions.

On Bars and Haloes: Their Interaction and Their Orbital Structure
Annals of the New York Academy of Sciences, 2005 Abstract: A live halo plays an active role in the formation and evolution of bars by participating in the angular momentum redistribution that drives the dynamical evolution. Angular momentum is emitted mainly by neae‐resonant material in the bar region and is absorbed mainly by near‐resonant material in the halo and in the outer disc.
