The binary fraction of planetary nebula central stars - III. the promise of VPHAS+
(2018-04-21)
The majority of planetary nebulae (PNe) are not spherical, and current single-star models cannot adequately explain all the morphologies we observe. This has led to the Binary Hypothesis, which states that PNe are ...
Diffuse gas in galaxies sheds new light on the origin of Type Ia supernovae
(2014-08-01)
We measure the strength of He II λ4686 nebular emission in passively evolving ('retired') galaxies, aiming to constrain their populations of hot accreting white dwarfs (WDs) in the context of the single-degenerate (SD) ...
