Nebulosa planetaria de estrella renacida. Hablamos con Martín Guerrero Roncel.

Las estrellas como el Sol, tras agotar su combustible nuclear, terminan su vida expulsando al espacio sus capas más externas. La materia expulsada forma una extensa nube de gas que envuelve a la estrella y se dispersa por el espacio lentamente. En condiciones normales, la energía desprendida por la estrella ioniza las regiones de gas más cercanas a ella, mientras que las regiones más alejadas y frías muestran menor ionización. Un equipo internacional de científicos, liderado por nuestro invitado, Martín Guerrero Roncel, astrofísico del IAA (CSIC), revela que la nebulosa HuBi1, en cambio, tiene un comportamiento opuesto al esperado.
