Resumen
Las explosiones de rayos gamma de larga duración (GRB) están relacionadas con la muerte de estrellas masivas. Una hipernova coincidiendo con un GRB proporciona una fuerte evidencia de que los eventos de colapso del núcleo desencadenan estas poderosas explosiones cósmicas, apoyando el modelo de colapso.
Área de la Ciencia:
- La astronomía y la astrofísica.
- Las explosiones cósmicas son explosiones cósmicas.
- Evolución Estelar Evolución Estelar
Sus antecedentes:
- Las explosiones de rayos gamma de larga duración (GRB) son las explosiones más luminosas del Universo.
- La evidencia previa sugería que los GRB se originan en el colapso de estrellas masivas, basado en asociaciones con supernovas y regiones de formación estelar.
Objetivo del estudio:
- Para investigar el vínculo directo entre los GRB de larga duración y la muerte de estrellas masivas.
- Proporcionar evidencia concluyente que apoye el modelo de colapso para la formación de GRB.
Principales métodos:
- La astronomía observacional es la astronomía de las observaciones.
- Análisis de las curvas y espectros de luz.
- Análisis de coincidencia temporal y espacial de un GRB y una hipernova.
Principales resultados:
- Se encontró que un evento de hipernova era temporal y espacialmente coincidente con un GRB con desplazamiento al rojo z = 0.1685.
- La supernova explotó pocos días después del GRB, lo que indica una estrecha relación causal.
Conclusiones:
- Los eventos de colapso del núcleo en estrellas masivas pueden producir GRB.
- Los hallazgos apoyan fuertemente el modelo de colapso para el origen de GRB de larga duración.

03:23Types of Radioactivity
The most common types of radioactivity are α decay, β decay, γ decay, neutron emission, and electron capture.
Alpha (α) decay is the emission of an α particle from the nucleus. For example, polonium-210 undergoes α decay:

02:50Nuclear Fission
Many heavier elements with smaller binding energies per nucleon can decompose into more stable elements that have intermediate mass numbers and larger binding energies per nucleon—that is, mass numbers and binding energies per nucleon that are closer to the “peak” of the binding energy graph near 56. Sometimes neutrons are also produced. This decomposition of a large nucleus into smaller pieces is called fission. The breaking is rather random with the formation of a large number of different...
02:45Nuclear Fusion
The process of converting very light nuclei into heavier nuclei is also accompanied by the conversion of mass into large amounts of energy, a process called fusion. The principal source of energy in the sun is a net fusion reaction in which four hydrogen nuclei fuse and ultimately produce one helium nucleus and two positrons.
A helium nucleus has a mass that is 0.7% less than that of four hydrogen nuclei; this lost mass is converted into energy during the fusion. This reaction produces about...

03:20Nuclear Transmutation
Nuclear transmutation is the conversion of one nuclide into another. It can occur by the radioactive decay of a nucleus, or the reaction of a nucleus with another particle. The first manmade nucleus was produced in Ernest Rutherford’s laboratory in 1919 by a transmutation reaction, the bombardment of one type of nuclei with other nuclei or with neutrons. Rutherford bombarded nitrogen-14 atoms with high-speed α particles from a natural radioactive isotope of radium and observed protons being...
01:06Nuclear Overhauser Enhancement (NOE)
Irradiation of a spin-active nucleus causes an increase or decrease in the signal intensity of neighboring nuclei that are not necessarily chemically bonded or involved in J-coupling. This phenomenon, called the nuclear Overhauser enhancement (NOE), results from through-space interactions between the nuclear spins. The NOE effect decreases with increasing internuclear distance and is generally not observed beyond 4 angstroms. In NOE, dipole-dipole interactions between neighboring spin-active...
01:19Thomson's e/m Experiment
In a beam of charged particles created by a heated cathode, the particles move at different speeds. However, many applications need a beam with uniform particle speeds. An arrangement known as a velocity selector uses electric and magnetic fields to pick particles with a particular speed from the beam.
A particle with charge q, speed v, and mass m enters an area from the top, where the magnetic and electric fields are perpendicular both to the particle's motion and to one another. The magnetic...
