From blue to red spirals: Slow galaxy transformation via ram pressure stripping in TNG-50

V. Lora, J. I. Gonzalez-Carbajal, A. Pasquali +5

Late-type galaxies lose gas through ram-pressure stripping (RPS) after falling into a massive halo. Because this mechanism primarily removes the gaseous component while leaving the…

Accretion onto WD 2226210, the central star of the Helix Nebula

S. Estrada-Dorado, M. A. Guerrero, J. A. Toalá +4

The central star of the Helix Nebula, WD 2226210 presents enigmatic hard X-ray emission and mid-IR excess. The latter has been attributed to a dusty disk or a cloud-like structu…

Synthetic X-ray emission from white dwarf accreting planetary material

S. Estrada-Dorado, V. Lora, J. A. Toalá +4

The emission of hard X-rays associated with white dwarfs (WD) can be generated by the presence of a stellar companion either by the companion's coronal emission or by an accretion…

XMM-Newton Detection of X-ray Emission from the Metal-Polluted White Dwarf G 29-38

S. Estrada-Dorado, M. A. Guerrero, J. A. Toalá +3

A recent analysis of Chandra X-ray data of the metal-polluted white dwarf (WD) G29-38 has revealed X-ray emission that can be attributed to the accretion of debris from a planetary…

Adjusting the bow-tie: A morpho-kinematic study of NGC40

J. B. Rodríguez-González, J. A. Toalá, L. Sabin +4

We present a comprehensive study of the ionization structure and kinematics of the planetary nebula (PN) NGC40 (a.k.a. the Bow-tie Nebula). A set of narrow-band images obtained wit…

Multiple variability time-scales of the early nitrogen-rich Wolf-Rayet star WR7

J. A. Toalá, D. Bowman, T. Van Reeth +7

We present the analysis of the optical variability of the early, nitrogen-rich Wolf-Rayet (WR) star WR7. The analysis of multi-sector Transiting Exoplanet Survey Satellite (TESS) l…

Carbon dust in the evolved born-again planetary nebulae A30 and A78

J. A. Toalá, P. Jiménez-Hernández, J. B. Rodríguez-González +6

We present an infrared (IR) characterization of the born-again planetary nebulae (PNe) A30 and A78 using IR images and spectra. We demonstrate that the carbon-rich dust in A30 and…

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…
