Grants for post-doctorants and PhD candidates

Are youa SF2A member and a post-doc or PhD candidate abroad and you could not participate in the SF2A Conference without a little financial help?  In this case, the SF2A can allocate you a grant. If you are interested, please send, before March 20th, to the President of SF2A with a copy to the secretary, a concise “motivation” letter accompanied by a short CV. Tell us which sessions you would like to attend and the realistic amount you would need (registration + accommodation + transport) to participate or to supplement funding already partially acquired. The format of these documents is free.

If your request is accepted, the SF2A will reimburse you the costs (adjusted to the actual amount), on invoice after the conference. A request for an advance will however be possible.

Contributions (abstracts)

Deadline to submit an abstract for workshops is April 25th.

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.
