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…
Detailed studies of IPHAS sources -- III. The highly extinguished bipolar planetary nebula IPHASX J191104.8060845
J. B. Rodríguez-González, L. Sabin, J. A. Toalá +6
We present the first detailed study of the bipolar planetary nebula (PN) IPHASX J191104.8060845 (PN G040.601.5) discovered as part of the Isaac Newton Telescope Photometric H…
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…
History of the mass ejection in K 4-37: from the AGB to the evolved planetary nebula phase
L. F. Miranda, P. F. Guillén, L. Olguín +1
We present narrow-, broad-band, and WISE archive images, and high- and intermediate-resolution long-slit spectra of K 4-37, a planetary nebula that has never been analyzed in detai…
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…
Millimeter polarisation of the protoplanetary nebula OH 231.8+4.2: A follow-up study with CARMA
L. Sabin, C. L. H. Hull, R. L. Plambeck +4
In order to investigate the characteristics and influence of the magnetic field in evolved stars, we performed a follow-up investigation of our previous submillimeter analysis of t…
The physical structure of planetary nebulae around sdO stars: Abell36, DeHt2, and RWT152
A. Aller, L. F. Miranda, L. Olguín +5
We present narrow-band Halpha and [OIII] images, and high-resolution, long-slit spectra of the planetary nebulae (PNe) Abell36, DeHt2, and RWT152 aimed at studying their morphology…
Submillimeter polarisation and magnetic field properties in the envelopes of proto-planetary nebulae CRL 618 and OH 231.8+4.2
L. Sabin, Q. Zhang, A. A. Zijlstra +5
We have carried out continuum and line polarisation observations of two Proto-planetary nebulae (PPNe), CRL 618 and OH 231.8+4.2, using the Submillimeter Array (SMA) in its compact…
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…
Detection of a multi-shell planetary nebula around the hot subdwarf O-type star 2MASS J19310888+4324577
A. Aller, L. F. Miranda, A. Ulla +8
(Abridged) The origin of hot subdwarf O-type stars (sdOs) remains unclear since their discovery in 1947. Among others, a post-Asymptotic Giant Branch (post-AGB) origin is possible…
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…
