EC 19529-4430: SALT identifies the most carbon- and metal-poor extreme helium star
Simon Jeffery, Laura Scott, Asish Philip Monai +2
EC 19529-4430 was identified as a helium-rich star in the Edinburgh-Cape Survey of faint-blue objects and subsequently resolved as a metal-poor extreme helium (EHe) star in the SAL…
Hot white dwarfs and pre-white dwarfs discovered with SALT
C. S. Jeffery, K. Werner, D. Kilkenny +3
The Southern African Large Telescope (SALT) survey of helium-rich hot subdwarfs aims to explore evolutionary pathways amongst groups of highly-evolved stars. The selection criteria…
The messy death of a multiple star system and the resulting planetary nebula as observed by JWST
Orsola De Marco, Muhammad Akashi, Stavros Akras +66
Planetary nebulae (PNe), the ejected envelopes of red giant stars, provide us with a history of the last, mass-losing phases of 90 percent of stars initially more massive than the…
A detailed study of the barium central star of the planetary nebula Abell 70
David Jones, Henri M. J. Boffin, Alex J. Brown +4
We present a detailed study of the barium star at the heart of the planetary nebula Abell 70. Time-series photometry obtained over a period of more than ten years demonstrates that…
The binary central star of the bipolar pre-planetary nebula IRAS 08005-2356 (V510 Pup)
Rajeev Manick, Brent Miszalski, Devika Kamath +5
Current models predict that binary interactions are a major ingredient for the formation of bipolar planetary nebulae (PNe) and pre-planetary nebulae (PPNe). Despite years of radia…
Multiplicity of Galactic Luminous Blue Variable stars
L. Mahy, C. Lanthermann, D. Hutsemékers +7
Context. Luminous Blue Variables (LBVs) are thought to be in a transitory phase between O stars on the main-sequence and the Wolf-Rayet stage. Recent studies suggest that they migh…
