Un equipo internacional de astr\u00f3nomos ha identificado en la nebulosa del Anillo una estructura inesperada, una nube de hierro con forma de barra, cuyo origen todav\u00eda no tiene explicaci\u00f3n clara.\u00a0<\/p>\n

Los detalles de esta nube de \u00e1tomos de hierro se publican en la revista Monthly Notices of the Royal Astronomical Society en un art\u00edculo firmado, entre otros, por cient\u00edficos del University College de Londres (UCL) y de la Universidad de Cardiff.<\/p>\n

Tiene forma de barra o franja y encaja perfectamente en la capa interna de la nebulosa, de geometr\u00eda el\u00edptica<\/p>\n

Tiene forma de barra o franja y encaja perfectamente en la capa interna de la nebulosa, de geometr\u00eda el\u00edptica, conocida por numerosas im\u00e1genes, incluidas las obtenidas por el telescopio espacial James Webb.<\/p>\n

<\/a><\/p>\n

Como la masa de Marte<\/h2>\n

La longitud de la barra es aproximadamente 500 veces la de la \u00f3rbita de Plut\u00f3n alrededor del Sol y, seg\u00fan el equipo, su masa de \u00e1tomos de hierro es comparable a la masa de Marte, seg\u00fan explican en sendos comunicados las instituciones brit\u00e1nicas.<\/p>\n

El hallazgo se produjo a partir de observaciones obtenidas con el modo Large Integral Field Unit (LIFU) de un nuevo instrumento, el WHT Enhanced Area Velocity Explorer (WEAVE), instalado en el telescopio William Herschel de 4,2 metros.<\/p>\n

El hallazgo se logr\u00f3 gracias a observaciones realizadas con un nuevo instrumento instalado en el telescopio William Herschel<\/p>\n

El William Herschel es el telescopio principal del Grupo de Telescopios Isaac Newton, que a su vez forma parte del Observatorio del Roque de los Muchachos, en La Palma (Islas Canarias). El grupo est\u00e1 operado conjuntamente por el Reino Unido, los Pa\u00edses Bajos y Espa\u00f1a, a trav\u00e9s del Instituto de Astrof\u00edsica de Canarias.<\/p>\n

\u201cAunque la nebulosa del Anillo se ha estudiado con muchos telescopios e instrumentos diferentes, WEAVE nos ha permitido observarla de una forma nueva, proporcionando muchos m\u00e1s detalles que antes\u201d, afirma Roger Wesson.<\/p>\n

Wesson a\u00f1ade que, al obtener un espectro continuo de toda la nebulosa, es posible crear im\u00e1genes en cualquier longitud de onda y determinar su composici\u00f3n qu\u00edmica en cualquier posici\u00f3n.<\/p>\n

Al procesar los datos y revisar las im\u00e1genes, una caracter\u00edstica destac\u00f3 con claridad: la barra de \u00e1tomos de hierro ionizados, hasta ahora desconocida, situada en medio del familiar e ic\u00f3nico anillo.<\/p>\n

<\/a><\/p>\n

Un misterio<\/h2>\n

Seg\u00fan los autores, su formaci\u00f3n es por ahora un misterio y ser\u00e1n necesarias observaciones m\u00e1s detalladas para desentra\u00f1ar qu\u00e9 est\u00e1 sucediendo.<\/p>\n

Hay dos posibles escenarios: la barra de hierro podr\u00eda revelar nueva informaci\u00f3n sobre c\u00f3mo progres\u00f3 la eyecci\u00f3n de la nebulosa por parte de la estrella madre o, lo que resulta m\u00e1s intrigante, el hierro podr\u00eda corresponder a un arco de plasma originado por la vaporizaci\u00f3n de un planeta rocoso atrapado en una fase anterior de expansi\u00f3n de la estrella.<\/p>\n

\u201cSin duda, necesitamos saber m\u00e1s, en particular si hay otros elementos qu\u00edmicos que coexistan con el hierro reci\u00e9n detectado, ya que esto probablemente nos indicar\u00eda el tipo de modelo adecuado que debemos seguir. En este momento, nos falta esta importante informaci\u00f3n\u201d, apunta por su parte Janet Drew.<\/p>\n

El equipo cree que podr\u00edan existir m\u00e1s barras de hierro en otras nebulosas similares, lo que ayudar\u00eda a explicar el origen de este elemento<\/p>\n

El equipo trabaja ya en un estudio de seguimiento y tiene previsto obtener nuevos datos con el LIFU de WEAVE, esta vez con una resoluci\u00f3n espectral m\u00e1s alta, para comprender mejor c\u00f3mo pudo haberse formado la barra.<\/p>\n

Wesson se\u00f1ala que \u201cser\u00eda muy sorprendente\u201d que la barra de hierro de la nebulosa del Anillo fuera \u00fanica. \u201cEsperamos que, a medida que observemos y analicemos m\u00e1s nebulosas creadas de la misma manera, descubramos m\u00e1s ejemplos de este fen\u00f3meno, lo que nos ayudar\u00e1 a comprender de d\u00f3nde proviene el hierro\u201d.<\/p>\n
