Virtual Online Meeting

Hosted by the NASA Exoplanet Science Institute, IPAC/Caltech

All attendees are required to read and adhere to the Code of Conduct posted here

Collaborative STEAM (Science, Technology, Engineering, Arts and Math) public outreach project

For this virtual conference, it has taken the form of daily e-zine of micro-fiction stories, poetry, and art inspired by the discoveries being presented at the conference, called "Heavy Metal Jupiters and Other Stories". It has been edited by Jessie Christiansen and Heather Clitheroe, and we are so grateful and excited by all the contributions!

Monday Zine The creative works in today's issue were inspired by the abstracts that will be presented today by Jason Rowe, Eric Nielsen, Arthur Vigan, and Kevin Schlaufman.

Tuesday Zine The creative works in today's issue were inspired by the abstracts that will be presented today by Ryan Cloutier, Andrew Neil, Daniel Thorngren, Rafael Luque, Sivan Ginzburg, and Jiayin Dong.

Wednesday Zine The creative works in today's issue were inspired by the abstracts that will be presented today by Martin Schlecker, Juliette Becker, Nader Haghighipour, and Sivan Ginzberg.

Thursday Zine The creative works in today's issue were inspired by the abstracts that will be presented today by Aida Behmard , Emily Safsten, Rachel Fernandes (she/her), Sam Grunblatt, Erik Dennihy , Matthias Schrieber, and Steve Lubow.

Friday Zine The creative works in today's issue were inspired by the abstracts that will be presented today by James Rogers, Kristin Sotzen, William Misener, Óscar Carrión- González, Samson Johnson, and Knicole Colon.

Conference Themes

The exoplanet field has transitioned rapidly from discovery to characterization. As the numbers of known exoplanets grows, our ability to discern and understand the underlying populations and planets that produce the observed distributions we see also grows. This conference will bring together community members working both theoretically and observationally on understanding exoplanet demographics.

  • What are the current limitations on our ability to discern the true underlying planet population from the observed distribution?
  • What can the size and/or mass distribution of exoplanets teach us about the dominant planet formation, migration, and evolution pathways?
  • What properties of stars affect the types of planets that form, and how can we use the properties of stars to study planet formation?
  • What can we learn from planetary systems or disks around stellar remnants and substellar objects?
  • How will upcoming missions advance our understanding of exoplanet demographics?

Agenda (updated 10/22; session chairs added)
Poster Presentations
  • Poster POPs: There are 45 slots in the agenda for poster POPs which are which will be 1-minute pre-recorded poster video "advertisements". These videos will be accepted on a first-come, first-served basis starting on Tuesday, Oct. 13 at 9 am Pacific until all slots are filled; video files should be emailed to; early submissions and re-submissions will not be accepted, so please plan to submit a final version of the video if you wish to present a poster POP. Topics directly related to the topic of the conference will be prioritized for POPs and we will accept one POP per person. Poster POPs are not required in order to present a poster.
  • Convert a Contributed Talk to a Poster: If your abstract was not selected for a talk, there is still time to submit it as a poster. You can email us at to let us know that you would like to convert your talk to a poster and we will add it to the poster listing.
  • Poster Discussion: We will be setting up a Slack workspace for the conference and there will be dedicated channels for posters sorted by major session topic on the agenda. In addition to having a PDF of your poster on the conference website, authors can put their posters in whatever flexible format you like (not restricted to pdf). Then people can 'reply' to that poster to start a thread for discussion of the poster.
Participant List (651)
Link to Register

Abstract submission is now closed.

Selection criteria: The SOC is committed to building an inclusive conference agenda, and is looking for ways to facilitate vibrant, thoughtful, and respectful discussions between all participants. Submissions are widely solicited and encouraged. Abstracts were anonymously ranked in three career stage categories (student, postdoc, and staff) using three criteria: originality of the work, relevance to the conference themes, and results.

Three types of presentations were selected:

  • Review Talks: 30 minute presentations that are intended to address one or more of the conference themes listed above. The review talks will provide the framework for the conference agenda, and therefore the submission deadline for review talks is May 8 and speakers can expect to be notified by May 22 about the outcome.
  • Contributed Talks: 15 minute presentations. We hope to accommodate as many requests as possible.
  • Poster Presentations: Poster presenters will have the opportunity to present a 1 minute poster POP during the conference. There will also be dedicated poster sessions. Each poster will have a 4' x 4' (1.2 m x 1.2 m) area for display.
