Resumen
El plasma solar de alta temperatura genera ondas gravitacionales estocásticas (GW). Este estudio reexamina estas ondas, incluidas las fluctuaciones hidrodinámicas, encontrando que su espectro está por debajo de las sensibilidades actuales del detector.
Área de la Ciencia:
- Física del plasma
- La astrofísica
- Astronomía de las ondas gravitacionales
Sus antecedentes:
- El plasma interior del Sol es una fuente significativa de ondas gravitacionales de alta frecuencia (GW).
- Estudios anteriores exploraron la emisión de axiones del Sol, teniendo en cuenta los efectos del plasma.
Objetivo del estudio:
- Para reexaminar la generación de ondas gravitacionales estocásticas en el interior solar.
- Investigar la contribución de las fluctuaciones hidrodinámicas macroscópicas a la emisión de GW.
- Para comparar el espectro de GW resultante con las señales del universo temprano y los límites actuales del detector.
Principales métodos:
- Análisis de los procesos físicos en el interior del plasma solar.
- Incorporación de fluctuaciones hidrodinámicas macroscópicas en los modelos de generación de GW.
- Comparación del espectro GW teórico con las sensibilidades experimentales.
Principales resultados:
- El plasma solar de alta temperatura genera ondas gravitacionales estocásticas.
- Las fluctuaciones hidrodinámicas macroscópicas contribuyen al espectro de GW.
- El espectro de GW predicho es de órdenes de magnitud por debajo de la sensibilidad de los helioscopios actuales como (Baby) IAXO.
Conclusiones:
- El interior del Sol es una fuente de ondas gravitacionales estocásticas de alta frecuencia.
- Las sensibilidades actuales del helioscopio axion son insuficientes para detectar estos GW solares.
- Se necesitan más avances en la tecnología de detectores para sondear esta fuente de GW astrofísica.

2.2K
No object with a finite mass can travel faster than the speed of light in a vacuum. This fact has an interesting consequence in the domain of extremely high gravitational fields.
The minimum speed required to launch a projectile from the surface of an object to which it is gravitationally bound so that it eventually escapes the object’s gravitational field is called the escape velocity. The escape velocity is independent of the mass of the object. Merging the idea of escape...

01:14Gravitation 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.

02:39Emission Spectra
64.5K
When solids, liquids, or condensed gases are heated sufficiently, they radiate some of the excess energy as light. Photons produced in this manner have a range of energies, and thereby produce a continuous spectrum in which an unbroken series of wavelengths is present.

01:17The Principle of Superposition and the Gravitational Field
1.5K
The principle of superposition applies to gravitational forces of objects that are sufficiently far apart. It states that the net gravitational force on a point object is the vector sum of the gravitational forces on it due to various objects. The principle helps calculate the force by listing the individual forces and then vectorially summing them up. However, it should be noted that the principle of superposition is not always apparent. In the presence of a second force, the first force could...

01:10Detection of Black Holes
2.3K
Although black holes were theoretically postulated in the 1920s, they remained outside the domain of observational astronomy until the 1970s.
Their closest cousins are neutron stars, which are composed almost entirely of neutrons packed against each other, making them extremely dense. A neutron star has the same mass as the Sun but its diameter is only a few kilometers. Therefore, the escape velocity from their surface is close to the speed of light.
Not until the 1960s, when the first neutron...

01:27Gravity between Spherical Bodies
8.6K
Newton's law of gravitation describes the gravitational force between any two point masses. However, for extended spherical objects like the Earth, the Moon, and other planets, the law holds with an assumption that masses of spherical objects are concentrated at their respective centers.
This assumption can be proved easily by showing that the expression for gravitational potential energy between a hollow sphere of mass (M) and a point mass (m) is the same as it would be for a pair of extended...
