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.…
Grantecan spectroscopic observations and confirmations of Planetary Nebulae candidates in the Northern Galactic Plane
A. Ritter, Q. A. Parker, L. Sabin +3
We present Grantecan 10 m telescope (GTC) spectroscopic confirmations of 55 faint Planetary Nebulae (PNe) candidates discovered largely in the INT Photometric H Survey of the N…
WHTZ 1: A high excitation Planetary Nebula not a gaseous cocoon from runaway star HD 185806
Quentin A. Parker, Pascal Le Dû, Andreas Ritter +6
We present evidence that the nebular cocoon and bow-shock emission nebula putatively and recently reported as deriving from the 9th magnitude "runaway" star HD 185806 is the previo…
A new study on a type Iax stellar remnant and its probable association with SN 1181
Foteini Lykou, Quentin A. Parker, Andreas Ritter +4
We report observations and modeling of the stellar remnant and presumed double-degenerate merger of Type~Iax supernova Pa30, which is the probable remnant of SN~1181~AD. It is the…
