Summary

Description
English: Artist's impression of an evolving white dwarf (foreground) and millisecond pulsar (background) binary system. Using the 4.1-meter SOAR Telescope on Cerro Pachón in Chile, part of Cerro Tololo Inter-American Observatory, a Program of NSF's NOIRLab, astronomers have discovered the first example of a binary system consisting of an evolving white dwarf orbiting a millisecond pulsar, in which the millisecond pulsar is in the final phase of the spin-up process. The source, originally detected by the Fermi Space Telescope, is a “missing link” in the evolution of such binary systems.
Español: Impresión artística de un sistema en binario en evolución compuesto por una una enana blanca (Primer plano) y un púlsar (plano de fondo) de milisegundos. Utilizando el telescopio SOAR de 4,1 metros en Chile, los astrónomos descubrieron el primer ejemplo de un sistema binario compuesto por una enana blanca en evolución que se encuentra orbitando un púlsar de milisegundos que se encuentra en la fase final del proceso de giro. La fuente, que fue detectada originalmente por el Telescopio Espacial Fermi, es un eslabón perdido en la evolución de este tipo de sistemas binarios.
