VLT VIMOS Integral Field Spectroscopy of the nova remnant FH Ser
M. A. Guerrero, E. Santamaria, L. Takeda +4
FH Ser experienced a slow classical nova outburst in February 1970 that was the first one observed at UV, optical, and IR wavelengths. Its nova remnant is elliptical in shape, with…
Confirmation of the planetary nebula nature of HaTr 5. Not the remnant of Nova Sco 1437
M. A. Guerrero, E. Santamaria, G. Liberato +6
The identification of the nebula HaTr 5 with the shell remnant of the historic Nova Sco 1437 around the low-accretion rate cataclysmic variable 2MASS J17022815-4306123 has been use…
The impact of periastron passage on the X-ray and optical properties of the Symbiotic System R Aquarii
D. A. Vásquez-Torres, J. A. Toalá, A. Sacchi +4
Multi-epoch Chandra and XMM-Newton observations of the symbiotic system R Aquarii (R Aqr) spanning 22 yr are analysed by means of a reflection model produced by an accretion disc.…
Shaping the nebula around the symbiotic system R Aquarii
E. Santamaría, J. A. Toalá, T. Liimets +4
We present an analysis of high-dispersion spectroscopic observations of the symbiotic system R Aquarii (R Aqr) obtained with the Manchester Echelle Spectrograph (MES) at the 2.1 m…
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…
