Abundances of PN towards Galactic bulge
Listed in IVOA Registry (Virtual Observatory)
In this work we report spectrophotometric observations of a planetary nebula sample towards the galactic bulge.
Description
A total of 45 PNe was observed and their physical parameters (electron density and temperature) were derived. Ionic abundances were calculated using a three-level atom model and abundances were derived through ionisation correction factors.
Results show low abundance objects at high galactic latitudes, indicating a possible vertical gradient inside the bulge. A few objects with low N/O ratio were found, which could have originated from old, low mass progenitors.
