Magnetohydrodynamical flows in young circumstellar disks
Focus workshop 1 - 5 October 2023
Magnetic fields crucially affect the gas dynamics in young circumstellar discs, and thus shape the gas and dust disk structure and its evolution. Implications range from where in the outer disk the dust grains can grow, over the formation of pressure maxima, that affect the concentration of pebbles, until the most inner regions, in which magnetic fields control the launching of magnetized winds and jets.
Consequently, the issue of magnetic flux evolution in young circumstellar disks (all the way from its initial collapse to its ultimate dispersal) is of central interest, and constitutes one of the most prominent unresolved questions in modern astrophysics.
Our goal for this workshop is to bring together experts in theory and observations of magnetic fields in circumstellar disks to answer key questions of modern astrophysics:
Consequently, the issue of magnetic flux evolution in young circumstellar disks (all the way from its initial collapse to its ultimate dispersal) is of central interest, and constitutes one of the most prominent unresolved questions in modern astrophysics.
Our goal for this workshop is to bring together experts in theory and observations of magnetic fields in circumstellar disks to answer key questions of modern astrophysics:
- What is the initial magnetic field configuration in a young circumstellar disk immediately after its formation?
- How does the magnetic flux evolve over the disk's lifetime?
- Which constraints from observations do we have on the topology and strength of the magnetic flux?
- What precise role do magnetic fields play for the disk wind and for the gas dynamics inside the disk?

Code of Conduct
We are committed to ensure an excellent workshop, regardless of gender, ethnicity, sexual orientation, religion and physical appearance. We will not tolerate any harassment, sexist or racist comments, and participants will be asked to comply with the Code of Conduct, reproduced below.
Please follow these guidelines:
1. Behave professionally. Harassment and sexist, racist, or exclusionary comments or jokes are not appropriate. Harassment includes sustained disruption of talks or other events, inappropriate physical contact, sexual attention or innuendo, deliberate intimidation, stalking, and photography or recording of an individual without consent. It also includes offensive comments related to individual characteristics, for example: age, gender, sexual orientation, disability, physical appearance, race, nationality or religion.
2. All communication should be appropriate for a professional audience including people of many different backgrounds. Sexual or sexist language and imagery is not appropriate.
3. Be respectful and do not insult or put down other attendees or facilitators of the event. Critique ideas not people.
4. Should a participant witness events of bullying, harassment or aggression, we recommend that they approach the affected person to show support and check how they are. The witness may also wish to suggest that the person report the inappropriate behaviour. However, it is up to the affected person alone whether or not they wish to report it.
5. If participants wish to share photos of a speaker on social media, we strongly recommend that they first get the speaker’s permission. Participants may also share the contents of talks/slides via social media unless speakers have asked that specific details/slides not be shared.
Participants can report any violation of these guidelines to the organizing committee in confidence.
