V618 Sgr: Galactic eclipsing symbiotic nova detected in repeated outbursts
J. Merc, R. Gális, P. Velez +9
V618 Sgr was previously classified as an R CrB-type variable and later as a possible symbiotic star. Our study aims to analyse the nature of this target, which is currently undergo…
ASASSN-21co: A detached eclipsing binary with an 11.9 year period
D. M. Rowan, K. Z. Stanek, Z. Way +10
We use ASAS V-band and ASAS-SN g-band observations to model the long-period detached eclipsing binary ASASSN-21co. ASAS observations show an eclipse of depth V ~ 0.6 mag in April o…
A high-mass Planetary Nebula in a Galactic Open Cluster
Vasiliki Fragkou, Quentin Parker, Albert Zijlstra +2
Planetary Nebulae are the ionised ejected envelopes surrounding the remnant cores of dying stars. Theory predicts that main-sequence stars with one to about eight times the mass of…
Flickering in AGB stars: Probing the nature of accreting companions
S. Snaid, A A. Zijlstra, I. McDonald +3
Binary companions to asymptotic giant branch (AGB) stars are an important aspect of their evolution. Few AGB companions have been detected, and in most cases it is difficult to dis…
The binary fraction of planetary nebula central stars: the promise of VPHAS+
Helen Barker, Albert Zijlstra, Orsola De Marco +5
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 Hypo…
The Binary Central Star of Hf 38
Helen Barker
Despite years of effort, the impact of central star binarity on planetary nebula formation and shaping remains unclear. This is hampered by the fact that detecting central star bin…
