Diverse Science from VLT imagery and spectroscopy of PNe in the Galactic Bulge
Quentin Parker, Shuyu Tan, Andreas Ritter +1
We have undertaken a deep investigation of a well defined sample of 136 PNe located in a 10x10 degree central region of the Galactic Bulge observed with the ESO VLT and supplemente…
Whither or wither the Sulfur Anomaly in Planetary Nebulae?
Shuyu Tan, Quentin Parker
We present a thorough investigation of the long standing sulfur anomaly enigma. Our analysis uses chemical abundances from the most extensive dataset available for 126 planetary ne…
A Catalogue of Planetary Nebulae Chemical Abundances in the Galactic Bulge
Shuyu Tan, Quentin A. Parker, Albert A. Zijlstra +1
In this, the third of a series of papers, we present well determined chemical abundances for 124 Planetary nebulae (PNe) in the Galactic bulge from deep, long-slit FORS2 spectra fr…
When the Stars Align: A 5 σ Concordance of Planetary Nebulae Major Axes in the Centre of our Galaxy
Shuyu Tan, Quentin A. Parker, Albert A. Zijlstra +2
We report observations of a remarkable major axes alignment nearly parallel to the Galactic plane of 5σ significance for a subset of bulge "planetary nebulae" (PNe) that host, or a…
Morphologies and Central Stars of Planetary Nebulae in the Galactic bulge from VLT, and Pan-STARRS imaging
Shuyu Tan, Quentin A. Parker, Albert Zijlstra +1
This is the first in a series of papers that present sets of different results for 136 compact, known planetary nebulae within a 10 10 degree region of the Galactic bulge.…
