Morphokinematical study of the planetary nebula Me2-1: Unveiling its point-symmetric and unusual physical structure
L. F. Miranda, R. Vázquez, L. Olguín +2
(Abridged) We present narrow-band images in several emission lines, and high- and intermediate-resolution long-slit spectra of Me2-1 to investigate its morphology and 3D structure,…
The reactivation of water maser emission in the planetary nebula IRAS 18061--2505 through a born-again episode
L. F. Miranda, O. Suárez, L. Olguín +12
Water maser emitting planetary nebulae (HO-PNe) are believed to be among the youngest PNe. We present new optical narrow- and broad-band images, intermediate- and high-resoluti…
The morpho-kinematical structure and chemical abundances of the complex planetary nebula NGC 1514
Alba Aller, Roberto Vázquez, Lorenzo Olguín +2
We present high-resolution, long-slit optical spectra and images of the planetary nebula NGC1514. The position velocity maps of the [OIII] emission line reveal complex kinematics w…
A Submillimeter Polarization Analysis of Frosty Leo
L. Sabin, Q. Zhang, R. Vázquez +1
We present a polarimetric investigation of the protoplanetary nebula Frosty Leo performed with the Submillimeter Array. We were able to detect, in the low continuum level (peak at…
Measuring the Expansion and Age of the Nova Shell IPHASXJ210204.7+471015
E. Santamaría, M. A. Guerrero, G. Ramos-Larios +4
The parallax expansion and kinematics of a nova shell can be used to assess its age and distance, and to investigate the interaction of the ejecta with the circumstellar medium. Th…
The interaction of the halo around the butterfly planetary nebula NGC650-1 with the interstellar medium
G. Ramos-Larios, M. A. Guerrero, A. Nigoche-Netro +7
With its bright and wide equatorial waist seen almost edge-on (the butterfly body) and the faint and broad bipolar extensions (the butterfly wings), NGC650-1 is the archetypical ex…
