A virtual interdisciplinary workshop on planetesimal formation via the streaming instability that explores the connection to protoplanetary disc observations and the Solar System minor bodies.
17-20 November
Start time: 17 November 16:00 Central European Time (in your timezone)
Two and a half contact hours, the same each day, with presentations on zoom, between 16:00-18:30 Brussels / 10:00-12:30 New York / 08:00-10:30 Denver / 23:00-01:30 Taipei
A slack workspace will be used for speaker Q&A, discussions and as place to host the posters.
You can register
here for the zoom event.
Please sign up before 13 November.
Registered participants will receive an invite to the slack workspace Monday 16 November.
Participants can choose to present a pdf poster on slack.
A title will be requested when you register, but there is no abstract required.
When contributing a poster, please register or let us know via email (michiel@astro.lu.se) before 12 November. Then you will get early access to the slack workspace (13-16 November) to upload your poster.
There are no size or style requirements for the pdf posters.
We have verified that uploading a classic A0-format pdf poster works, however,
if you wish to, you are welcome to take advantage of the online format and
present content like videos, papers and links, in addition to the pdf poster.
Each talk will be about 10 minutes, review talks will be about 20 minutes. Talks are presented live on zoom and recorded (for participants only).
