摘要

描述HD 131399.jpg	English: This annotated composite image shows the newly discovered exoplanet HD 131399Ab in the triple-star system HD 131399. The image of the planet was obtained with the SPHERE imager on the ESO Very Large Telescope in Chile. This is the first exoplanet to be discovered by SPHERE and one of very few directly-imaged planets. With a temperature of around 580 degrees Celsius and an estimated mass of four Jupiter masses, it is also one of the coldest and least massive directly-imaged exoplanets. This picture was created from two separate SPHERE observations: one to image the three stars and one to detect the faint planet. The planet appears vastly brighter in this image than in would in reality in comparison to the stars. Español: Esta composición con anotaciones muestra el exoplaneta HD 131399Ab, recientemente descubierto en el sistema triple de estrellas HD 131399. Las imágenes del planeta fueron obtenidas con el instrumento SPHERE, instalado en el VLT (Very Large Telescope) de ESO, en Chile. Este es el primer exoplaneta descubierto por SPHERE y uno de los pocos planetas de los que se ha obtenido una imagen directa. Con una temperatura de alrededor de 580 grados centígrados y una masa estimada de cuatro masas de Júpiter, es también uno de los exoplanetas más fríos y menos masivos captados con imagen directa. Esta imagen se ha creado a partir de dos imágenes obtenidas por SPHERE, una llevada a cabo para captar una imagen de las tres estrellas y otra para captar al débil planeta. En esta imagen, el planeta aparece mucho más brillante de lo que en realidad lo veríamos en comparación con las estrellas.
