Oscillations about an Equilibrium Position

Oscillations about an Equilibrium Position

Stability is an important concept in oscillation. If an equilibrium point is stable, a slight disturbance of an object that is initially at the stable equilibrium point will cause the object to oscillate around that point. For an unstable equilibrium point, if the object is disturbed slightly, it will not return to the equilibrium point. There are three conditions for equilibrium points—stable, unstable, and half-stable. A half-stable equilibrium point is also unstable, but is named so...

Forced Oscillations

Forced Oscillations

When an oscillator is forced with a periodic driving force, the motion may seem chaotic. The motions of such oscillators are known as transients. After the transients die out, the oscillator reaches a steady state, where the motion is periodic, and the displacement is determined.

Reduced Mass Coordinates: Isolated Two-body Problem

Reduced Mass Coordinates: Isolated Two-body Problem

In classical mechanics, the two-body problem is one of the fundamental problems describing the motion of two interacting bodies under gravity or any other central force. When considering the motion of two bodies, one of the most important concepts is the reduced mass coordinates, a quantity that allows the two-body problem to be solved like a single-body problem. In these circumstances, it is assumed that a single body with reduced mass revolves around another body fixed in a position with an...

Damped Oscillations

Damped Oscillations

In the real world, oscillations seldom follow true simple harmonic motion. A system that continues its motion indefinitely without losing its amplitude is termed undamped. However, friction of some sort usually dampens the motion, so it fades away or needs more force to continue. For example, a guitar string stops oscillating a few seconds after being plucked. Similarly, one must continually push a swing to keep a child swinging on a playground.
Although friction and other non-conservative...

Gravitation Between Spherically Symmetric Masses

Gravitation Between Spherically Symmetric Masses

The gravitational potential energy between two spherically symmetric bodies can be calculated from the masses and the distance between the bodies, assuming that the center of mass is concentrated at the respective centers of the bodies.

Symmetry in Maxwell's Equations

Symmetry in Maxwell's Equations

Once the fields have been calculated using Maxwell's four equations, the Lorentz force equation gives the force that the fields exert on a charged particle moving with a certain velocity. The Lorentz force equation combines the force of the electric field and of the magnetic field on the moving charge. Maxwell's equations and the Lorentz force law together encompass all the laws of electricity and magnetism. The symmetry that Maxwell introduced into his mathematical framework may not be...

Background:

Boson stars are hypothetical compact objects composed of scalar bosons.
Understanding the full parameter space of boson star solutions is crucial for theoretical astrophysics.
Previous models primarily focused on single-frequency or simplified multi-frequency scenarios.

Purpose of the Study:

To investigate the existence and properties of stable boson stars with multiple noncommensurate oscillation frequencies.
To explore the parameter space of these novel multi-frequency boson star solutions.
To compare the characteristics of multi-frequency boson stars with standard single-frequency solutions.

Main Methods:

Numerical construction of two-frequency boson star solutions.
Exploration of the parameter space for these solutions.
Analysis of the limiting behavior as frequencies are turned off.

Main Results:

Stable boson stars can belong to an infinite-parameter family with multiple oscillation frequencies.
Two-frequency solutions were successfully constructed and their parameter space explored.
These solutions exhibit significant variations in size compared to standard boson stars at fixed energy.

Conclusions:

The family of stable boson star solutions is more extensive than previously thought, including multi-frequency configurations.
Multi-frequency boson stars represent a new class of solutions with potentially distinct observational signatures.
This work opens avenues for exploring more complex boson star configurations and their astrophysical implications.
