In order to enable an iCal export link, your account needs to have an API key created. This key enables other applications to access data from within Indico even when you are neither using nor logged into the Indico system yourself with the link provided. Once created, you can manage your key at any time by going to 'My Profile' and looking under the tab entitled 'HTTP API'. Further information about HTTP API keys can be found in the Indico documentation.
Additionally to having an API key associated with your account, exporting private event information requires the usage of a persistent signature. This enables API URLs which do not expire after a few minutes so while the setting is active, anyone in possession of the link provided can access the information. Due to this, it is extremely important that you keep these links private and for your use only. If you think someone else may have acquired access to a link using this key in the future, you must immediately create a new key pair on the 'My Profile' page under the 'HTTP API' and update the iCalendar links afterwards.

Forming Earths and Mercuries: solids less volatile than water
Life requires a variety of chemicals and elements. The question of water,
how it was delivered to Earth and how it would be delivered to exoplanets,
has taken a central position. However, other chemicals and elements are
also important. Earth is significantly (~80%) depleted in elements
important for life like sodium and potassium, both much less volatile than
water, but much more volatile than silicon, magnesium, or iron. Part of
the composition of planets is set during their formation process, when the
solids are still in sub-cm dust grains. I will discuss both the supply of
moderately volatile elements to the proto-Earth, and why Mercury is
extremely iron rich. Both processes should play major roles in exoplanet
formation, with consequences for their chemistry and hence any possible
