Central-star extinctions towards planetary nebulae
Alexander Csukai, Albert A. Zijlstra, Iain McDonald +1
Planetary nebulae trace the hottest and most luminous phase of evolution of solar-type stars. We use these hot, bright stars to investigate extinctions towards a complete sample of…
Three-dimensional simulations of accretion disks in pre-CE systems
Ana L. Juarez-Garcia, Orsola De Marco, Fabio De Colle +4
Before a binary system enters into a common envelope (CE) phase, accretion from the primary star onto the companion star through Roche Lobe overflow (RLOF) will lead to the formati…
Novel Constraints on Companions to the Helix Nebula Central Star
Leyla Iskandarli, Jay Farihi, Joshua D. Lothringer +3
The Helix is a visually striking and the nearest planetary nebula, yet any companions responsible for its asymmetric morphology have yet to be identified. In 2020, low-amplitude ph…
High-Speed Outflows and Dusty Disks during the AGB to PN Transition: The PANORAMA survey
Raghvendra Sahai, Javier Alcolea, Bruce Balick +15
As mass-losing asymptotic giant branch (AGB) stars evolve to planetary nebulae (PNe), the mass outflow geometries transform from nearly spherical to extreme aspherical. The physica…
Binary Central Stars of Planetary Nebulae Identified With Kepler/K2
George H. Jacoby, Todd C. Hillwig, David Jones +6
We present the identification of 34 likely binary central stars (CSs) of planetary nebulae (PNe) from {\it Kepler/K2} data, seven of which show eclipses. Of these, 29 are new disco…
Bipolar Planetary Nebulae from Outflow Collimation by Common Envelope Evolution
Yangyuxin Zou, Adam Frank, Zhuo Chen +8
The morphology of bipolar planetary nebulae (PNe) can be attributed to interactions between a fast wind from the central engine and dense toroidal shaped ejecta left over from comm…
