J/AJ/123/269        New SMC planetary nebulae                (Jacoby+, 2002)

A survey for very faint planetary nebulae in the SMC. I. Identification, confirmation, and preliminary analysis. Jacoby G.H., De Marco O. <Astron. J., 123, 269-278 (2002)> =2002AJ....123..269J
ADC_Keywords: Magellanic Clouds; Planetary nebulae Keywords: galaxies: individual (Small Magellanic Cloud) - planetary nebulae: general - stars: AGB and post-AGB - stars: evolution Abstract: Using the ESO 2.2m telescope with the 8Kx8K mosaic CCD, we have surveyed 2.8deg2 (∼1.6°x1.7°) of the Small Magellanic Cloud (SMC) to search for faint planetary nebulae (PNs); 34 PNs were previously known in this central region. We identified 25 new PNs, all faint and spectroscopically confirmed. File Summary:

Note (1): The magnitudes have uncertainties of 0.1mag in their zero points. In addition, the magnitudes have measurement accuracies that are no better than 0.05mag. The number of significant figures in the magnitude values reflects the accuracy of the estimate. Note (2): The image diameter is the approximate PN diameter measured from the [O III] difference image, while the spectroscopic diameter is the diameter of the PN measured from the brightest line in the spectrum - often [O III]λ5007, along the slit length from the CTIO 4m spectroscopy. The lack of a value in this column indicates that the PN diameter was smaller than the seeing.
