Planetary nebulae with Wolf-Rayet-type central stars -- III. A detailed view of NGC 6905 and its central star
V. M. A. Gómez-González, G. Rubio, J. A. Toalá +6
We present a multi-wavelength characterisation of the planetary nebula (PN) NGC 6905 and its [Wolf-Rayet]-type ([WR]) central star (CSPN) HD 193949. Our Nordic Optical Telescope (N…
Planetary nebulae with Wolf-Rayet-type central stars -- II. Dissecting the compact planetary nebula M2-31 with GTC MEGARA
J. S. Rechy-García, J. A. Toalá, S. Cazzoli +4
We present a comprehensive analysis of the compact planetary nebula M2-31 investigating its spectral properties, spatio-kinematical structure and chemical composition using GTC MEG…
Tomography of the unique on-going jet in the planetary nebula NGC 2392
M. A. Guerrero, S. Cazzoli, J. S. Rechy-Garcia +5
Jets (fast collimated outflows) are claimed to be the main shaping agent of the most asymmetric planetary nebula (PNe) as they impinge on the circumstellar material at late stages…
Discovery of a Fast Expanding Shell in the Inside-out Born-Again Planetary Nebula HuBi 1 Through High-Dispersion Integral Field Spectroscopy
J. S. Rechy-García, M. A. Guerrero, E. Santamaría +8
HuBi 1 has been proposed to be member of the rare class of born-again planetary nebulae (PNe), i.e., its central star experienced a very late thermal pulse and ejected highly-proce…
Unveiling the stellar origin of the Wolf-Rayet nebula NGC6888 through infrared observations
G. Rubio, J. A. Toalá, P. Jiménez-Hernández +5
We present a comprehensive infrared (IR) study of the iconic Wolf-Rayet (WR) wind-blown bubble NGC6888 around WR136. We use Wide-field Infrared Survey Explorer (WISE), Spitzer IRAC…
Planetary nebulae with Wolf-Rayet-type central stars -- I. The case of the high-excitation NGC 2371
V. M. A. Gómez-González, J. A. Toalá, M. A. Guerrero +4
We present the analysis of the planetary nebula (PN) NGC 2371 around the [Wolf-Rayet] ([WR]) star WD 0722295. Our Isaac Newton Telescope (INT) Intermediate Dispersion Spectrogra…
The Bubble Nebula NGC 7635 -- testing the wind-blown bubble theory
J. A. Toalá, M. A. Guerrero, H. Todt +5
We present a multiwavelength study of the iconic Bubble Nebula (NGC 7635) and its ionising star BD602522. We obtained XMM-Newton EPIC X-ray observations to search for…
Wolf-Rayet stars in M81 using GTC/OSIRIS: 7 new detections, analysis and classification of the full sample
V. M. A. Gómez-González, Y. D. Mayya, D. Rosa-González +3
We report the detection of 7 new Wolf-Rayet (WR) star locations in M81 using the Multi-Object Spectrograph of the OSIRIS instrument at Gran Telescopio Canarias. These detections ar…
