Investigadores de Warwick pronostican tonos verdes y rosados en enanas blancas

Investigadores de la Universidad de Warwick declararon que algunos enanos blancos podrían presentar tonos verdes o rosados porque elementos atmosféricos como el sodio y el calcio absorben determinadas longitudes de onda, según su último estudio. Esta conclusión se basa en trabajos previos del mismo equipo, que modelaron los colores visibles de los enanos blancos y describieron una gama de posibles matices.

Anteriormente anunciaron el descubrimiento de WD J1330+6435, un enano blanco a unos 326 años luz que muestra un leve resplandor verde debido al sodio procedente de restos planetarios, constituyendo la primera estrella verde confirmada. Sus modelos también identificaron el enano blanco de tono rosado más intenso conocido.
