Dear members of Division H,

This is a friendly reminder that the abstract deadline and the grant application deadline are February 28th for submission of contributed talks to IAU Symposium 345, ​"Origins: From the Protosun to the First Steps of Life". The symposium will take place at the IAU General Assembly in Vienna Austria from August 20-23.

The web site for the symposium is: http://ninlil.elte.hu/IAUS345/

If you have not registered, then the place to go is here: http://astronomy2018.univie.ac.at/registration/

After you register, you will get an email acknowledgement from "congress" with the subject line "Registration Confirmation: XXX IAU General Assembly". The link for your abstract submission should be at the bottom of that email.

We are pleased to announce the following invited speakers, who will lead the main sessions:

• Mike Juvela (Finland): Star Formation in the solar neighborhood -- surveys, generalities, simulations
• Christoph Federrath (Australia): Star formation in cloud cores – simulations and observations of dense molecular cores and the formation of solar mass stars
• Edward Young (USA): Early environment of the pre-solar nebula - isotopic anomalies in meteorites and the implications for nearby supernovae; physics of presolar nebulae, single versus binary star formation
• Laura Perez (Chile): Formation and evolution of protoplanetary disks - observations and modeling of jets, disks, and disk substructures
• Inga Kamp (Netherlands): Physical and chemical properties of protoplanetary disks - chemical composition, organics, planetesimals, planetary embryos; snow line; complex molecules; temperatures and densities; magnetic fields
• Eiichiro Kokubo (Japan): Formation of Earth and Earth-like planets
• Doris Breuer (Germany): Early planetary atmospheres and surfaces, origin of the Earth's water, crust and atmosphere
• Helmut Lammer (Austria): Early conditions on the Earth; general conditions for habitability - young stellar output, stellar winds and activity
• Daniel Apai (USA): Earth-like planets - observations, properties
• Addy Pross (Israel): Early life on Earth – tracing the physical/chemical process from non-living to living

A related summer school will be held the weekend before the Symposium: “Basics of Astrobiology,”organized by the University of Vienna, 17-18 August 2018. For more information see: http://ninlil.elte.hu/boa/

We hope to see you there!
