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…
VISIR-VLT high resolution study of the extended emission of four obscured post-AGB candidates
M. W. Blanco, M. A. Guerrero, G. Ramos-Larios +4
The onset of the asymmetry of planetary nebulae (PNe) is expected to occur during the late Asymptotic Giant Branch (AGB) and early post-AGB phases of low- and intermediate-mass sta…
An updated catalog of OH-maser-emitting planetary nebulae
L. Uscanga, J. F. Gómez, O. Suárez +1
Aims. We studied the characteristics of planetary nebulae (PNe) that show both OH maser and radio continuum emission (hereafter OHPNe). These have been proposed to be very young PN…
VISIR-VLT Images of the Water Maser Emitting Planetary Nebula K 3-35
Mónica W. Blanco, Martín A. Guerrero, Luis F. Miranda +2
K3-35 is an extremely young bipolar planetary nebula that contains a precessing bipolar jet and a small (radius 80 AU) water maser equatorial ring. We have obtained VISIR- VLT imag…
Water maser emission in planetary nebulae
L. F. Miranda, O. Suárez, J. F. Gómez
Planetary Nebulae (PNe) evolve from Asymptotic Giant Branch (AGB) stars after a brief post-AGB phase. Water maser emission is characteristic of oxygen-rich AGB stars, is observed i…
Water maser detections in southern candidates to post-AGB stars and Planetary Nebulae
O. Suárez, J. F. Gómez, L. F. Miranda +4
We intended to study the incidence and characteristics of water masers in the envelopes of stars in the post-AGB and PN evolutionary stages. We have used the 64-m antenna in Parkes…
