The origin of the planetary nebula M 1-16. A morphokinematic and chemical analysis
M. A. Gómez-Muñoz, R. Vázquez, L. Sabin +4
We investigated the origin of the Planetary Nebula (PN) M 1-16 using narrow-band optical imaging, and high- and low-resolution optical spectra to perform a detailed morpho-kinemati…
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…
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…
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…
Observations of the planetary nebula RWT 152 with OSIRIS/GTC
A. Aller, L. F. Miranda, L. Olguín +2
RWT 152 is one of the few known planetary nebulae with an sdO central star. We present subarcsecond red tunable filter Halpha imaging and intermediate-resolution, long-slit spectro…
GTC/OSIRIS observations of RWT 152, a case study of a planetary nebula with an sdO central star
A. Aller, L. F. Miranda, L. Olguín +2
RWT 152 is one of the few planetary nebula with an sdO central star. We present subarcsecond red tunable filter imaging and intermediate-resolution, long-slit spectroscopy of RWT 1…
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…
First release of the IPHAS Catalogue of New Extended Planetary Nebulae
L. Sabin, Q. A. Parker, R. L. M Corradi +21
We present the first results of our search for new, extended Planetary Nebulae (PNe) based on careful, systematic, visual scrutiny of the imaging data from the INT Photometric H-al…
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…
New Galactic supernova remnants discovered with IPHAS
L. Sabin, Q. A. Parker, M. E. Contreras +7
As part of a systematic search programme of a 10-degree wide strip of the Northern Galactic plane we present preliminary evidence for the discovery of four (and possibly five) new…
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…
