Registration process:

The registration to Cool Stars 21 is a two-step process:

  1. Click on this link to start your registration and pay the registration fee. Warning #1 : this step will not be validated until you complete the payment form. Make sure to get your credit card or bank details (if you choose the bank transfer option) nearby. Warning #2 : do not cancel the registration process at the payment step, or you will not be allowed to start the procedure again with the same email address (a different email address would do the trick, though). Warning #3 : participants affiliated to a French laboratory should NOT use their lab's credit card, but choose the "bon de commande" option in the payment interface.
  3. Once the first step is completed, you should receive a confirmation email from AzurColloque, and a second email with an invitation to complete your registration (this message may take a few hours to be sent). Click on the link in the email and fill the form. You're done!
If something goes wrong or if you need any help, just send an email to the LOC.

Registration and grant request:

Grants will cover the early bird registration fee and the Conference dinner. If you plan to apply for financial support, we ask you to wait until the SOC decision before registering. If your grant request is approved, you will have access to a separate, free of charge registration channel.

Cancellation policy:

To cancel your participation, send an email to the LOC. 100% refund will be offered if (1) the cancellation is done less than 60 days after the registration and (2) the cancellation is done before June 1st.
