Grants for post-doctorants and PhD students

Are you a post-doc or PhD student out of France who would like a grant to attend the Journées 2023. In that case send an email, before March 12th, to the President of SF2A with a copy to the secretary, including a letter of “motivation” along with a current CV. Tell us which sessions you would like to attend and how much money you need to participate. The format of these documents is free. If granted, refund will be done on the basis of your receipts and a non-payment certificate from your home institute.

Contributions (abstracts)

Deadline to submit an abstract for workshops is March 27th.

The submission of a contribution (or two) can be done by filling or modifying the registration form. You could then select the workshop in which you wish to submit your contribution (talk or poster). Up to two contributions can be submitted. If you want to submit more contributions, please contact the system administrator.

ePosters: only eposters will be available. They will be display online for all participants available from their computers. ePosters allow presenters to more effectively convey information that would not be feasible with a traditional printed poster, and it improves visualization to attract the attention of attendees while also conserving the environment!

Later on, a “book of abstracts” will be available online (and only online).

The proceedings of the conference give an annual overview of the current state of French astronomy. They will be published in an electronic format in English and made available on the SF2A website. They will be referenced in ADS. The instructions for the authors will be given later.
