SALT reveals the barium central star of the planetary nebula Hen 2-39
B. Miszalski, H. M. J Boffin, D. Jones +6
Classical barium stars are binary systems which consist of a late-type giant enriched in carbon and slow neutron capture (s-process) elements and an evolved white dwarf (WD) that i…
An Interacting Binary System Powers Precessing Outflows of an Evolved Star
Henri M. J. Boffin, Brent Miszalski, Thomas Rauch +5
Stars are generally spherical, yet their gaseous envelopes often appear non-spherical when ejected near the end of their lives. This quirk is most notable during the planetary nebu…
IC 4663: The first unambiguous [WN] Wolf-Rayet central star of a planetary nebula
B. Miszalski, P. A. Crowther, O. De Marco +4
We report on the serendipitous discovery of the first central star of a planetary nebula (PN) that mimics the helium- and nitrogen-rich WN sequence of massive Wolf-Rayet (WR) stars…
A barium-rich binary central star in Abell 70
Henri M. J. Boffin, B. Miszalski, D. J. Frew +4
We have found the central star of Abell 70 (PN G038.1-25.4, hereafter A 70) to be a binary consisting of a G8 IV-V secondary and a hot white dwarf. The secondary shows enhanced Ba…
A barium central star binary in the Type-I diamond ring planetary nebula Abell 70
B. Miszalski, H. M. J. Boffin, D. J. Frew +4
Abell 70 (PN G038.1-25.4, hereafter A 70) is a planetary nebula (PN) known for its diamond ring appearance due a superposition with a background galaxy. The previously unstudied ce…
The influence of binarity on dust obscuration events in the planetary nebula M 2-29 and its analogues
B. Miszalski, J. Mikołajewska, J. Köppen +8
The central star of the planetary nebula (CSPN) M 2-29 shows an extraordinary R Coronae Borealis-like fading event in its optical lightcurve. The only other CSPN to show these even…
