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…
Decentralized nation, solving the web identity crisis
Frederic Jumelle, Timothy Pagett, Ryan Lemand
The web of today whether you prefer to call it web 2.0, web 3.0, web 5.0 or even the metaverse is at a critical stage of evolution and challenge, largely centered around its crisis…
The Planetary Nebula in the 500 Myr old Open Cluster M37
Vasiliki Fragkou, Quentin A. Parker, Albert A. Zijlstra +3
We report confirmation of a large, evolved, bipolar planetary nebula and its blue, white dwarf central star as a member of the ~500 Myr old Galactic open star cluster M37 (NGC 2099…
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…
