Asymmetrical Post-main-sequence Nebulae 8 e2021

The Shaping of Stellar Outflows

Links to webpages with contributed talks and e-Posters

A virtual meeting hosted in Granada, Spain held in October 4-8, 2021.

The meeting is devoted to the shaping effects of stellar outflows from evolved stars in the formation of asymmetrical post-main-sequence nebulae including planetary nebulae, nebulae around massive stars, nova remnants, symbiotic stars, ...

Three main topics will be covered:

I. Nebular Architecture: morphologies and dynamics across stellar mass and wavelength.

- Multi-wavelength properties of planetary nebulae and related nebulae, including nebulae around evolved massive stars, symbiotic stars, nova remnants, …

- Morphological diversity and statistics.

- Accreting and circumbinary disks: getting closer to the launching engine of collimated outflows and jets.

II. Nebular Sequences: time-evolving morphologies and physical structures.

- Nebular evolution from the ejection time to its dilution into the ISM.

- Comparative studies between proto-PNe and PNe and between pre-explosion shells and post-explosion remnants in CVs and evolved massive stars.

- Transient nebulae: born-again PNe, nova shells, and other eruptive objects and transients

III. The Engine of the Nebular Shaping: mass-loss mechanisms and their effects on the winds symmetry.

- Post-MS binary interactions: wide, close and interacting binaries, common envelopes, planets.

- Magnetic fields: strength, structure, effects, statistics.

- Mass-loss mechanisms: radiation pressure on dust, convection, rotation, non-radial pulsations.

- Collateral effects on stellar evolution, planetary nebulae population, chemistry.

This APN8e virtual meeting will move to the full traditional meeting format in Granada, Spain (Fall 2023 or Spring 2024)

The APN 8-e2021 meeting consist of 12-minute oral contributions and e-Posters (up to 2-minute videos or PDF files).
