Journal ArticleDOI
Binary planetary nebulae nuclei towards the Galactic bulge - I. Sample discovery, period distribution, and binary fraction
Brent Miszalski,Brent Miszalski,A. Acker,Anthony F. J. Moffat,Quentin A. Parker,Andrzej Udalski +5 more
TL;DR: In this article, the OGLE microlensing survey with the largest sample of planetary nebulae towards the Galactic bulge was used to systematically search for new binary central stars.
Journal ArticleDOI
Binary planetary nebulae nuclei towards the Galactic bulge - II. A penchant for bipolarity and low-ionisation structures
TL;DR: In this article, the discovery of several new binary central stars (CSPN) from the OGLE-III photometric variability survey has significantly increased the number of post-CE PNe available for morphological analysis to 30 PNe.
Journal ArticleDOI
A barium central star binary in the Type I diamond ring planetary nebula Abell 70
Brent Miszalski,Henri M. J. Boffin,David J. Frew,A. Acker,Joachim Köppen,Joachim Köppen,Joachim Köppen,Anthony F. J. Moffat,Quentin A. Parker,Quentin A. Parker +9 more
TL;DR: A 70 (PN G038.1−25.4, hereafter A 70) is a planetary nebula known for its diamond ring appearance due to a superposition with a background galaxy.
Journal ArticleDOI
The influence of binarity on dust obscuration events in the planetary nebula M 2-29 and its analogues
Brent Miszalski,Brent Miszalski,Brent Miszalski,Joanna Mikolajewska,Joachim Köppen,Joachim Köppen,Joachim Köppen,Thomas Rauch,A. Acker,Martin Cohen,David J. Frew,Anthony F. J. Moffat,Quentin A. Parker,Quentin A. Parker,Albert F. Jones,Andrzej Udalski +15 more
TL;DR: The central star of the planetary nebula (CSPN) M 2-29 shows an extraordinary R Coronae Borealis-like fading event in its optical lightcurve as mentioned in this paper.
Journal ArticleDOI
Discovery of eclipsing binary central stars in the planetary nebulae M 3-16, H 2-29, and M 2-19
TL;DR: In this article, the authors used photometric data from the third phase of the Optical Gravitational Lensing Experiment (OGLE) to search for periodic variability in a large sample of planetary nebulae towards the Galactic Bulge using Fourier and phase-dispersion minimisation techniques.
