The planetary nebula nature and properties of IRAS18197-1118
L. F. Miranda, L. F. Rodriguez, C. B. Pereira +1
IRAS18197-1118 is a stellar-like object that has been classified as a planetary nebula from its radio continuum emission and high [SIII]9532 to Paschen9 line intensity ratio, as de…
On the relationship between the H2 emission and the physical structure of planetary nebulae
R. A. Marquez-Lugo, G. Ramos-Larios, M. A. Guerrero +1
Mid-IR observations of planetary nebulae (PNe) have revealed diffuse emission associated to their main nebular shells and outer envelopes or haloes. The interpretation of this emis…
The filamentary Multi-Polar Planetary Nebula NGC 5189
L. Sabin, R. Vázquez, J. A. López +2
We present a set of optical and infrared images combined with long-slit, medium and high dispersion spectra of the southern planetary nebula (PN) NGC 5189. The complex morphology o…
Observational Study of the Multistructured Planetary Nebula NGC 7354
M. E. Contreras, R. Vázquez, L. F. Miranda +3
We present an observational study of the planetary nebula (PN) NGC 7354 consisting of narrowband Halpha and [NII]6584 imaging as well as low- and high-dispersion long-slit spectros…
UBV(RI)_C photometry of the open clusters Be 15, Be 80, and NGC 2192
M. T. Tapia, W. J. Schuster, R. Michel +4
The three open clusters Be 15, Be 80, and NGC 2192 have been observed using CCD UBV(RI)_C photometry at the San Pedro Mártir Observatory, México within the framework of our open-cl…
