RCN Events

Full RCN Meeting -- October 20th, 2022

The RCN steering committee is excited to announce that we’ll be holding the first full RCN meeting on October 20th, 2022 from 8a - 12p Pacific (11a-3p Eastern, 4p-8p UK, and 5p-9p CEST)!

This all-digital meeting will feature:

  • Discussions on how the RCN can best serve the community

  • Tutorials on RV-related software packages

  • Science presentations, with a focus on works-in-progress that may benefit from collaborations or community input

  • Networking opportunities for early career EPRV scientists

Ahead of the meeting, the RCN steering committee is looking for community input! We’d like to hear from you about:

  • What EPRV-adjacent software packages would you be interested in learning more about, especially via a hands-on tutorial? We’ll be reaching out to creators ahead of the meeting, and want to know who you’d most like to learn from. If you’d like to submit a suggestion/request, or volunteer to give a tutorial on your own software, please do so using this Google Form.
  • Would you be interested in giving a short format talk (5-15 minutes, depending on the final meeting structure) about a current/recent research effort? If so, please do so using this Google Form. We are especially interested in hearing about works-in-progress that may benefit from new collaborations or community input, and in hearing from early career researchers, but the invite to apply is open to all RCN members.

We request that all talk submissions and tutorial requests be submitted by Sept. 15.

Extreme Precision RV Foundational Science Seminar
April 26th, 2022

This seminar featured the PIs from NASA’s 2021 ROSES call on ‘EPRV Foundation Science’ which focused on new pathways to mitigating stellar variability in (E)PRV data. Each speaker described the scope of their project and provided updates on their teams progress in the first year+ of effort. You will find more details below, including the program schedule, presentation abstracts, and connection information.

A full recording of the seminar is available on the RCN Google Drive
