XMM-Newton Detection of X-Ray Emission from the Metal-polluted White Dwarf G 29-38

Autor: S. Estrada-Dorado, M. A. Guerrero, J. A. Toalá, Y.-H. Chu, V. Lora, C. Rodríguez-López

Publikováno v: The Astrophysical Journal Letters, Vol 944, Iss 2, p L46 (2023)

A recent analysis of Chandra X-ray data of the metal-polluted white dwarf G 29-38 has revealed X-ray emission that can be attributed to the accretion of debris from a planetary body. In the light of this detection we revisit here archival XMM-Newton

We present an infrared (IR) characterization of the born-again planetary nebulae (PNe) A 30 and A 78 using IR images and spectra. We demonstrate that the carbon-rich dust in A 30 and A 78 is spatially coincident with the H-poor ejecta and coexists wi

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

Autor: J B Rodríguez-González, J A Toalá, L Sabin, G Ramos-Larios, M A Guerrero, J A López, S Estrada-Dorado

We present a comprehensive study of the ionization structure and kinematics of the planetary nebula (PN) NGC 40 (a.k.a. the Bow-tie Nebula). A set of narrow-band images obtained with the Alhambra Faint Object Spectrograph and Camera at the Nordic Opt

Multiple variability time-scales of the early nitrogen-rich Wolf-Rayet star WR 7

Autor: J A Toalá, D M Bowman, T Van Reeth, H Todt, K Dsilva, T Shenar, G Koenigsberger, S Estrada-Dorado, L M Oskinova, W-R Hamann

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) light curves and high-resolution spectroscopic observations confirm mul

We present the analysis of XMM–Newton European Photon Imaging Camera (EPIC) observations of the nova shell IPHASX J210204.7+471015. We detect X-ray emission from the progenitor binary star with properties that resemble those of underluminous interm
