3D physical structure and angular expansion of the remnant of the recurrent nova T Pyx
E. Santamaría, J. A. Toalá, M. A. Guerrero +2
We present the analysis of archival Very Large Telescope (VLT) MUSE and multi-epoch Hubble Space Telescope (HST) WFPC2 and WFC3/UVIS narrow-band observations of the remnant associa…
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…
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…
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…
Spatio-kinematic models of five nova remnants: correlations between nova shell axial ratio, expansion velocity, and speed class
E. Santamaría, M. A. Guerrero, S. Zavala +3
We present long-slit intermediate-dispersion spectroscopic observations and narrow-band direct imaging of four classical nova shells, namely TAur, HRDel, DQHer and QUVul, and the n…
