Morpho-kinematics of the planetary nebula NGC 3242: an analysis beyond its multiple-shell structure
M. A. Gómez-Muñoz, M. W. Blanco Cárdenas, R. Vázquez +3
In this paper we present the results of optical high-resolution imaging and spectroscopy of the complex planetary nebula (PN) NGC~3242. Our study is based on the analysis of the na…
Multiple outflows in the planetary nebula NGC 6058
P. F. Guillén, R. Vázquez, L. F. Miranda +4
We present narrow-band [O III]lambda5007 and H-alpha images, as well as long-slit high-resolution echelle spectra of the planetary nebula NGC 6058. Our data reveal that NGC 6058 is…
Resolving the CO Snow Line in the Disk around HD 163296
Chunhua Qi, Paola D'Alessio, Karin I. Oberg +4
We report Submillimeter Array (SMA) observations of CO (J=2--1, 3--2 and 6--5) and its isotopologues (13CO J=2--1, C18O J=2--1 and C17O J=3--2) in the disk around the Herbig Ae sta…
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…
The physical structure of the point-symmetric and quadrupolar planetary nebula NGC 6309
R. Vázquez, L. F. Miranda, L. Olguín +4
We analyse the point-symmetric planetary nebula NGC 6309 in terms of its three-dimensional structure and of internal variations of the physical conditions to deduce the physical pr…
Optical and Near Infrared Study of the Cepheus E outflow, a very low excitation object
S. Ayala, A. Noriega-Crespo, P. M. Garnavich +4
We present images and spectra of the Cepheus E (Cep E) region at both optical and infrared wavelengths. Only the brightest region of the southern lobe of the Cep E outflow reveals…
