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…
3D mapping of the Wolf-Rayet nebula M1-67: clues for post-common envelope evolution in massive stars
S. Zavala, J. A. Toalá, E. Santamarí +5
We present a 3D mapping of the Wolf-Rayet (WR) nebula M1-67 around WR124. We obtained high-resolution San Pedro Mártir (SPM) Manchester Echelle Spectrograph (MES) observations alon…
Common envelope evolution in born-again planetary nebulae -- Shaping the H-deficient ejecta of A30
J. B. Rodríguez-González, E. Santamaría, J. A. Toalá +7
Born-again planetary nebulae (PNe) are extremely rare cases in the evolution of solar-like stars. It is commonly accepted that their central stars (CSPN) experienced a very late th…
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…
X-ray observations of the nova shell IPHASX J210204.7+471015
J. A. Toalá, G. Rubio, E. Santamaría +4
We present the analysis of XMM-Newton European Photon Imaging Camera (EPIC) observations of the nova shell IPHASX J210204.7471015. We detect X-ray emission from the progenitor b…
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…
