Planetary nebulae with Wolf-Rayet-type central stars -- IV. NGC 1501 and its mixing layer
G. Rubio, J. Toalá, H. Todt +4
Theory predicts that the temperature of the X-ray-emitting gas (10 K) detected from planetary nebulae (PNe) is a consequence of mixing or thermal conduction when in con…
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…
QU Vul: An Integral Field Spectroscopy Case Study of a Nova Shell
E. Santamaría, M. A. Guerrero, J. A. Toalá +2
We present GTC MEGARA high-dispersion integral field spectroscopic observations of the nova remnant QU\,Vul, which provide a comprehensive 3D view of this nova shell. The tomograph…
Two temperate super-Earths transiting a nearby late-type M dwarf
L. Delrez, C. A. Murray, F. J. Pozuelos +82
In the age of JWST, temperate terrestrial exoplanets transiting nearby late-type M dwarfs provide unique opportunities for characterising their atmospheres, as well as searching fo…
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…
Adjusting the bow-tie: A morpho-kinematic study of NGC40
J. B. Rodríguez-González, J. A. Toalá, L. Sabin +4
We present a comprehensive study of the ionization structure and kinematics of the planetary nebula (PN) NGC40 (a.k.a. the Bow-tie Nebula). A set of narrow-band images obtained wit…
