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…
Discovery of a Fast Expanding Shell in the Inside-out Born-Again Planetary Nebula HuBi 1 Through High-Dispersion Integral Field Spectroscopy
J. S. Rechy-García, M. A. Guerrero, E. Santamaría +8
HuBi 1 has been proposed to be member of the rare class of born-again planetary nebulae (PNe), i.e., its central star experienced a very late thermal pulse and ejected highly-proce…
Unveiling the stellar origin of the Wolf-Rayet nebula NGC6888 through infrared observations
G. Rubio, J. A. Toalá, P. Jiménez-Hernández +5
We present a comprehensive infrared (IR) study of the iconic Wolf-Rayet (WR) wind-blown bubble NGC6888 around WR136. We use Wide-field Infrared Survey Explorer (WISE), Spitzer IRAC…
Extended X-ray emission from the classic nova DQ Her -- On the possible presence of a magnetized jet
J. A. Toalá, M. A. Guerrero, E. Santamaría +2
We present an analysis of archival Chandra and XMM-Newton observations of the magnetically-active cataclysmic variable DQ Her and the shell around it ejected in a nova event in 193…
Angular Expansion of Nova Shells
E. Santamaría, M. A. Guerrero, G. Ramos-Larios +4
Nova shells can provide us with important information on their distance, their interactions with the circumstellar and interstellar media, and the evolution in morphology of the ej…
Measuring the Expansion and Age of the Nova Shell IPHASXJ210204.7+471015
E. Santamaría, M. A. Guerrero, G. Ramos-Larios +4
The parallax expansion and kinematics of a nova shell can be used to assess its age and distance, and to investigate the interaction of the ejecta with the circumstellar medium. Th…
