Andromeda's tenuous veil: A likely Milky Way nebula projected toward M31
A. Lumbreras-Calle, J. A. Fernández-Ontiveros, R. Infante-Sainz +10
A large, faint nebula was unexpectedly discovered near M31 using narrowband [O III] images. Its apparent size and the lack of a clear counterpart at other wavelengths make it uniqu…
Optical tomography of the born-again ejecta of A 58
B. Montoro-Molina, D. Tafoya, M. A. Guerrero +2
In a born-again planetary nebula (PN), processed H-deficient material has been injected inside the old, H-rich nebula as a result of a very late thermal pulse (VLTP) event. Long-sl…
Spatially-resolved spectroscopic investigation of the born-again planetary nebula A 78
B. Montoro-Molina, M. A. Guerrero, J. A. Toalá
We present the analysis of spatially-resolved spectroscopic observations of the born-again planetary nebula (PN) A 78 that are used to investigate the chemistry and physical proper…
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…
Chemistry and physical properties of the born-again planetary nebula HuBi 1
B. Montoro-Molina, M. A. Guerrero, B. Pérez-Díaz +4
The central star of the planetary nebula (PN) HuBi\,1 has been recently proposed to have experienced a very late thermal pulse (VLTP), but the dilution of the emission of the recen…
Formation and fate of the born-again planetary nebula HuBi 1
J. A. Toalá, V. Lora, B. Montoro-Molina +2
We present the first 3D radiation-hydrodynamic simulations on the formation and evolution of born-again planetary nebulae (PNe), with particular emphasis to the case of HuBi1, the…
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…
