Scalar field self-force effects on orbits about a Schwarzschild black hole
, 2004 For a particle of mass mu and scalar charge q, we compute the effects of the scalar field self-force upon circular orbits, upon slightly eccentric orbits and upon the innermost stable circular orbit of a Schwarzschild black hole of mass M.

Circular orbits and photon orbits at wormhole throats
Physical Review DIn this work we study timelike circular orbits and photon orbits at the throat of stationary and axisymmetric wormholes. We assume a global radial coordinate l connecting both sides, with twice differentiable metric components and vanishing first ...

Measurement of spin–orbit torque using field counterbalancing in radial current geometry
Scientific Reports, 2023 Controlling the direction of magnetization with an electric current, rather than a magnetic field, is a powerful technique in spintronics. Spin–orbit torque, which generates an effective magnetic field from the injected current, is a promising method for

Circular orbits inside the sphere of death [PDF]
American Journal of Physics, 1998 A wheel or sphere rolling without slipping on the inside of a sphere in a uniform gravitational field can have stable circular orbits that lie wholly above the “equator,” while a particle sliding freely cannot.

Entropy, 2023 The many problems faced by the theory of general relativity (GR) have always motivated us to explore the modified theory of GR. Considering the importance of studying the black hole (BH) entropy and its correction in gravity physics, we study the ...

Post-Newtonian Models of Binary Neutron Stars [PDF]
, 1997 Using an energy variational method, we calculate quasi-equilibrium configurations of binary neutron stars modeled as compressible triaxial ellipsoids obeying a polytropic equation of state.

Pediatric Blood &Cancer, EarlyView.ABSTRACT Blinatumomab has been shown to be highly effective for patients with pediatric B‐ALL and has recently become standard of care therapy. Due to its past use in the clinical trial setting, there is limited information available about real‐world administration.

Three-body orbital stability criteria for circular orbits [PDF]
Monthly Notices of the Royal Astronomical Society, 1992 Previous investigations of the stability of hierarchical three-body systems by Harrington (1972, Cel. Mech., 1; 1975, AJ, 80 and 1977, AJ, 82), and by Black (1982, AJ, 87), Graziani & Black (1981, ApJ, 251) and Pendleton & Black (1983, AJ, 88) give conflicting results. A new numerical examination of such systems and the corresponding stability criteria
