PLANETARY NEBULAE IN THE INNER MILKY WAY II: THE BULGE-DISK TRANSITION
(UNIV NACIONAL AUTONOMA MEXICO, INST DE ASTRONOMIA, 2011)
In this work, a sample of planetary nebulae located in the inner-disk and bulge of the Galaxy is used in order to find the galactocentric distance which better separates these two populations, from the point of view of ...
Planetary nebulae and determination of the bulge-disk boundary
(International Astronomical UnionBeijing, 2012)
In this paper, a sample of planetary nebulae in the Galaxy's inner-disk and bulge is used to find the galactocentric distance that optimally separates these two populations in terms of their abundances. Statistical distance ...

In this paper, a sample of planetary nebulae in the Galaxy's inner-disk and bulge is used to find the galactocentric distance that optimally separates these two populations in terms of their abundances. Statistical distance ...
H(2) infrared line emission from the ionized region of planetary nebulae
(EDP SCIENCES S A, 2011)
Context. The analysis and interpretation of the H(2) line emission from planetary nebulae have been done in the literature by assuming that the molecule survives only in regions where the hydrogen is neutral, as in ...
Towards an improvement in the spectral description of central stars of planetary nebulae
(EDP Sciences, 2018-02)
Context. There are more than 3000 known Galactic planetary nebulae, but only 492 central stars of Galactic planetary nebulae (CSPN) have known spectral types. It is vital to increase this number in order to have reliable ...
ERRATUM: “THE IRON ABUNDANCE IN GALACTIC PLANETARY NEBULAE” (2009, ApJ, 694, 1335)
(The Astrophysical Journal, 2011)
Catalogue of the central stars of planetary nebulae: Expanded edition
(EDP Sciences, 2020-08)
Planetary nebulae represent a potential late stage of stellar evolution, however, their central stars (CSPNe) are relatively faint and, therefore, pertinent information is available for merely < 20 of the Galactic sample. ...
