Glossary term: Remanentes estelares
Description: «Remanentes estelares» o «restos estelares» es el término colectivo que designa a las enanas blancas, las estrellas de neutrones y los agujeros negros de masa estelar. Estos representan la etapa final de la evolución estelar, una vez que una estrella ha completado la combustión del hidrógeno en la secuencia principal y ha pasado por la fase de gigante. Los remanentes estelares son muy compactos en comparación con las estrellas. Las enanas blancas (el tipo más grande de remanente estelar) contienen aproximadamente una masa solar de materia en un objeto del tamaño de la Tierra. Los remanentes estelares no generan calor mediante fusión nuclear en sus núcleos. En los sistemas binarios cercanos, los restos estelares pueden ser el origen de novas, supernovas de tipo Ia o (si dos restos estelares se acercan en espiral el uno al otro y chocan) ráfagas de ondas gravitacionales.

Death of a massive star
Caption: A multi-wavelength image taken with telescopes on the Earth and in space of a neutron star within our neighbouring Small Magellanic Cloud galaxy. A neutron star (seen here as the blue spot surrounded by a red ring) is the final product of gravitational collapse, compression and explosion of a massive star, left embedded in its supernova remnant (in green).

Remnant of SN 1006
Caption: This image shows the remnant of the supernova SN 1006. This was probably the result of a white dwarf that accreted so much material from a binary companion star that the white dwarf exploded (this is called a Type 1a supernova by astronomers). This explosion happened several thousand years ago, however it took time for the light from this event to reach Earth, only arriving in the year 1006. This bright explosion was noticed by observers across the Earth and its appearance was noted in the records of many different societies.
Here we see the effect that supernova has had on its surroundings in the galaxy. The force of the explosion has blown a huge bubble in the surrounding interstellar gas with a hot shockwave at its edge. The image appears to be a simple color picture but it actually represents light far beyond what our eye can see. The blue is X-ray data from NASA's Chandra X-ray Observatory, the yellow and orange are data from optical telescopes and the red is detections in radio waves from the Very Large Array and the Green Bank Telescope. The bright blue of the outer shell shows the gas there is very hot and that the explosion produced energetic shock waves.

The Crab Pulsar
Caption: At the heart of the Crab Nebula, situated approximately 6,500 light-years away in the constellation of Taurus, lies the Crab Nebula Pulsar. This is remnant of a massive star that exploded at the end of its life. This happened several thousand years ago but the light from this explosion only reached the Earth in the year 1054. This celestial event was viewed by people across the world with many different societies noting it in their records.
The Crab Nebula Pulsar rotates about 30 times per second and emits light in many different wavelengths, including the visible spectrum. It is roughly one and a half times the mass of the sun but the force of the explosion that formed it crammed this mass into a tiny space, roughly ten kilometres in radius.
This image is a composite of several observations conducted by the Gemini North observatory in Hawaii, USA. The pulsar can be seen at the center. The observations that this image was created from were taken over a period of five years. Data from 2009 is shown in blue and data from 2014 is shown in red. Over this time material has flowed away from the pulsar resulting in this colored ripple effect. Again the colors do not show real colors in the image, the ripples show the positions of the shockwaves as they moved away from the pulsar and hit into the surrounding gas.
