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…
