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…
From outburst to quiescence: spectroscopic evolution of V1838 Aql imbedded in a bow-shock nebula
J. V. Hernández Santisteban, J. Echevarría, S. Zharikov +15
We analyse new optical spectroscopic, direct-image and X-ray observations of the recently discovered a high proper motion cataclysmic variable V1838 Aql. The data were obtained dur…
Lightcurves for asteroids 18301 Konyukhov and 2022 West
Sinhué A. R. Haro-Corzo, Luis A. Villegas, Lorenzo Olguín +7
We report photometric analysis of two main-belt asteroids observed at the Observatorio Astronomico Nacional in the Sierra San Pedro Martir, Baja California, México. For 18301 Konyu…
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…
Catching a Grown-Up Starfish Planetary Nebula: I. Morpho-Kinematical study of PC 22
L. Sabin, M. A. Gómez-Muñoz, M. A. Guerrero +9
We present the first part of an investigation on the planetary nebula (PN) PC 22 which focuses on the use of deep imaging and high resolution echelle spectroscopy to perform a deta…
