RESUMEN
]]> Presentamos mapas, perfiles y fotometría de 24 nebulosas planetarias (NPs) detectadas en el estudio del plano galáctico en el infrarrojo medio (MIR) de GLIMPSE 3D. Las NPs muestran muchas de las propiedades observadas en estudios previos de estas fuentes, incluyendo la evidencia de emisión a mayores longitudes de onda afuera de las zonas ionizadas, una consecuencia probable de la emisión de hidrocarburos aromáticos policíclicos (PAHs) dentro de las regiones de fotodisociación (PDRs). Notamos también variaciones en los cocientes de flujo 5.8 µm/4.5 µm y 8.0 µm/4.5 µm con respecto a la distancia del núcleo; presentamos evidencia de un aumento en la emisión MIR en los halos de las fuentes y encontramos evidencia de variaciones en color respecto de la evolución nebular.
ABSTRACT
We present mapping, profiles and photometry for 24 planetary nebulae (PNe) detected in the GLIMPSE 3D mid–infrared (MIR) survey of the Galactic plane. The PNe show many of the properties observed in previous studies of these sources, including evidence for longer wave emission from outside of the ionised zones, a likely consequence of emission from polycyclic aromatic hydrocarbons (PAHs) within the nebular photo–dissociation regimes (PDRs). We also note variations in 5.8 µm/4.5 µm and 8.0 µm/4.5 µm flux ratios with distance from the nuclei; present evidence for enhanced MIR emission in the halos of the sources; and note evidence for variations in colour with nebular evolution.
Key Words: infrared: ISM — ISM: jets and outflows — planetary nebulae: general.
