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…
The inside-out planetary nebula around a born-again star
Martin A. Guerrero, Xuan Fang, Marcelo M. Miller Bertolami +8
Planetary nebulae are ionized clouds of gas formed by the hydrogen-rich envelopes of low- and intermediate-mass stars ejected at late evolutionary stages. The strong UV flux from t…
Discovery of a new classical nova shell around a nova-like cataclysmic variable
Martin A. Guerrero, Laurence Sabin, Gagik Tovmassian +8
The morphology and optical spectrum of IPHASXJ210205+471015, a nebula classified as a possible planetary nebula, are however strikingly similar to those of ATCnc, a classical nova…
The interaction of the halo around the butterfly planetary nebula NGC650-1 with the interstellar medium
G. Ramos-Larios, M. A. Guerrero, A. Nigoche-Netro +7
With its bright and wide equatorial waist seen almost edge-on (the butterfly body) and the faint and broad bipolar extensions (the butterfly wings), NGC650-1 is the archetypical ex…
