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…
Detailed studies of IPHAS sources -- III. The highly extinguished bipolar planetary nebula IPHASX J191104.8060845
J. B. Rodríguez-González, L. Sabin, J. A. Toalá +6
We present the first detailed study of the bipolar planetary nebula (PN) IPHASX J191104.8060845 (PN G040.601.5) discovered as part of the Isaac Newton Telescope Photometric H…
A Preferred Orientation Angle for Bipolar Planetary Nebulae
Andreas Ritter, Quentin A. Parker
We present preliminary results from measuring Galactic orientation angles of 800 elliptical and bipolar Planetary Nebulae (PNe) in the Hong Kong/Australian Astronomical Observatory…
The Sixth Data Release of the Radial Velocity Experiment (RAVE) -- II: Stellar Atmospheric Parameters, Chemical Abundances and Distances
Matthias Steinmetz, Guillaume Guiglion, Paul J. McMillan +58
We present part 2 of the 6th and final Data Release (DR6 or FDR) of the Radial Velocity Experiment (RAVE), a magnitude-limited (9<I<12) spectroscopic survey of Galactic stars rando…
The Sixth Data Release of the Radial Velocity Experiment (RAVE) -- I: Survey Description, Spectra and Radial Velocities
Matthias Steinmetz, Gal Matijevic, Harry Enke +59
The Radial Velocity Experiment (RAVE) is a magnitude-limited (9<I<12) spectroscopic survey of Galactic stars randomly selected in the southern hemisphere. The RAVE medium-resolutio…
The Radial Velocity Experiment (RAVE): Fifth Data Release
Andrea Kunder, Georges Kordopatis, Matthias Steinmetz +51
Data Release 5 (DR5) of the Radial Velocity Experiment (RAVE) is the fifth data release from a magnitude-limited (9< I < 12) survey of stars randomly selected in the southern hemis…
Be Stars in the Open Cluster NGC 6830
Po-Chieh Yu, Chien-Cheng Lin, Hsing-Wen Lin +18
We report the discovery of 2 new Be stars, and re-identify one known Be star in the open cluster NGC 6830. Eleven H-alpha emitters were discovered using the H-alpha imaging photome…
