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.

Star and planet formation is one of the basic physical processes in the universe, and has extensively been studied observationally and theoretically over more than 30 years. It is not only a structure-formation process, but also a chemical-evolution process of interstellar matter toward stars and planets. Observational understanding of the chemical evolution is an important target for modern astronomy, which would possibly be related to an origin of life. On the other hand, chemical compositions of the star forming clouds are sensitive to physical conditions and evolutionary history. Hence, they can be useful tools to investigate physical processes of star and planet formation.
With these in mind, we are studying chemical evolution of molecular clouds mainly by millimeter- and submillimeter-wave observations. In this talk, I am going to introduce our continuous study on the chemical evolution from starless cores to star-forming cores. In particular, we have recently found star forming cores, L1527 and IRAS15398-3359, which have different chemical compositions from others. In these sources, various carbon-chain molecules are extremely abundant in the vicinity of the protostars (Warm Carbon Chain Chemistry: WCCC). Discovery of the WCCC sources means that star-forming cores have a significant chemical variation, even if they look similar in physical properties. An origin of the chemical variation is discussed in relation to the difference in star-formation processes.
