Planetary Nebulae with DENIS
The last, and only, attempt to survey the sky in the near infrared range was the TMSS (Neugebauer & Leighton, 1969). This survey contains mainly bright stars. The Deep Near Infrared Southern Sky Survey (DENIS) is the first attempt to survey all the southern sky in the near infrared (NIR) range in three bands; I, J and Ks (Epchtein et al., 1994). Planetary nebulae (PNe) were investigated by means of aperture photometers (e.g. Whitelock 1985, Kwok et al. 1986, Pena & Torres-Peimbert 1987, Preite-Martinez & Persi 1989, Phillips & Cuesta 1994) in the past. These investigations often use J, H and K bands. Thus the DENIS survey will lead, due to different bands and the total sky coverage, to a new view on PNe in this wavelength domain. We show here the capabilities of investigations of PNe with the DENIS data, being comparable in spatial resolution, will also support investigation at longer wavelengths (Kimeswenger et al., 1997a) done with the ISOCAM instrument (Cesarsky et al., 1996). Spatially resolved observations also provide better information about the contamination of the red (or highly reddened) foreground stars. The survey also will uncover the nature of several objects suspected to be PNe by means of their IRAS colors, but having no optical identification yet.
