Presolar grains - A session in honor of Ernst Zinner 
Conveners: Peter Hoppe and Larry Nittler

Presolar grains are found in small quantities in a variety of primitive Solar System materials. These grains formed in the winds of evolved stars and in the ejecta of stellar explosions and laboratory studies on these pristine samples have provided a wealth of astrophysical information. Ernst Zinner (1937-2015) pioneered the laboratory study of individual presolar grains and this session will honor his many contributions to this field. Contributions covering all aspects of presolar grain research, from laboratory studies to astrophysical modelling, are welcome. The session will start with a keynote lecture by Maria Lugaro, Konkoly Observatory, Hungarian Academy of Sciences, Budapest, Ungarn, on Stellar grains in the laboratory: Messengers from the Sky.

 

From meteorites to planets – A session in honor of Heinrich Wänke
Conveners: Herbert Palme, Katharina Lodders, and Klaus Keil 

The major themes of this sessions are the formation and bulk chemical and isotopic composition of the terrestrial planets including the Moon, as well as meteorites and their parent bodies. We welcome contributions about nebular and planetary fractionation processes, and isotope studies related to time scales of planet formation and differentiation.

 

Small meteorite impacts - From atmospheric entry to environmental effects 
Conveners: Witold Szczucinski, Anna Losiak and Jürgen Oberst

There is growing interest in small impacts on surface of the terrestrial planets. However, so far researchers often focused on selected aspects, e.g. atmospheric entry, crater formation, field studies or modeling. This session aims to integrate the various viewpoints on processes involved in small (decameter-size and smaller) meteoroid passing of the atmosphere, impact craters formation, and resulting various environmental effects. We invite contribution coming from various ground-based, airborne, or space-based
observational techniques, geological studies of meteorites, impact sites and sedimentary records of associated environmental changes, as well as from a range of modeling and experimental studies.

The session is linked to post-conference Excursion to Morasko Crater Field (Poland).

 

Surface and interior dynamics of meteorite parent bodies
Conveners: Wladimir Neumann, Stephanie Werner, Doris Breuer

The session will gather researchers of different communities for a better understanding of the evolution and (surface) properties of small bodies, in particular the parent bodies of the meteorites.
We welcome contributions on the study of exogenous and endogenous processes (incuding studies of the surface dynamics as well as statistical and numerical impact models) and on the evolution of specific parent bodies of meteorites as well as investigations across the continuum of small bodies (comets, planetesimals, asteroids, dwarf planets) ranging from local and short-term to global and long-term (thermal and thermochemical) processes.

 

Planetary evolution: Advances in meteoritical and lunar isotopic analyses
Conveners: Fienke Nanne, Mario Fischer-Gödde, Helen Williams, and Amy Riches

Radiogenic, stable, and nucleosynthetic isotopic systematics determined for elements of varying condensation temperatures and differing geochemical properties place key constraints on the origin and evolution of planetary bodies and their volatile inventories. Such data, determined for returned lunar samples and all forms of meteorite [at various analytical scales], are sensitive recorders of both the nature of chemical processes and their rates and/or timing. These observations provide crucial insight into the conditions prevalent in the early Solar System, and during the latter 4.5 Gyrs of planetary growth, ultimately resulting in a habitable Earth. We encourage the submission of all presentations providing relevant high-precision isotopic data and/or analytical advances as relate to meteoritical, lunar, and experimental analogue studies.

This special session is open to all potential contributors and is allied with the 4th International Workshop on Highly Siderophile Element Geochemistry.

 

 

Rosetta: To Catch a Comet!

Prof. Mark McCaughrean

The European Space Agency's Rosetta mission captured the imagination of the world in 2014, as it rendezvoused with Comet 67P/Churyumov-Gerasimenko and deployed a lander, Philae, to its surface. In this talk, I'll give a behind-the-scenes view of the mission, its history, the 10-year journey to reach the comet, and the exciting events that have been taking place there. I'll talk about some of the challenges and risks involved in the mission, and give some insights into the key scientific findings revealed to date about the formation of our solar system, the origins of water and perhaps even life on Earth. And to end, a look forward to the final phase of the mission, now that Rosetta, Philae, and the comet are past their closest approach to the Sun and heading back out into the cold.

Prof Mark McCaughrean is Senior Science Advisor in the Directorate of Science at the European Space Agency. He is also responsible for communicating results from ESA’s astronomy, heliophysics, planetary, and fundamental physics missions to the scientific community and wider general public. Following a PhD from the University of Edinburgh, he worked at the NASA Goddard Space Flight Centre, followed by astronomical institutes in Tucson, Heidelberg, Bonn, and Potsdam, and taught as a professor of astrophysics at the University of Exeter before joining ESA in 2009. His personal scientific research involves observational studies of the formation of stars and their planetary systems, and he is also an Interdisciplinary Scientist for the NASA/ESA/CSA James Webb Space Telescope.

Stellar Grains in the Laboratory: Messengers from the Sky !

Dr. Maria Lugaro

The detailed, extensive analysis of meteoritic stardust pioneered and led by Ernst Zinner in the past three decades provides us with revolutionary methodologies to investigate astrophysical questions. Decoding the message carried by stardust is challenging, but opens up fresh opportunities, leading to breakthroughs into our understanding of the creation of nuclei and dust in stars and of the chemodynamical evolution of the Milky Way. In this talk I will give an overview of the unique information that can be derived from the interpretation of stardust on currently debated topics in astrophysics, from supernova explosions, to the binary properties of massive stars, the origin of the elements heavier than iron, and stellar migration in the galaxy. Further current and future prospects involve coupling stardust data with bulk rock and leachates data to disentangle nucleosynthetic components in the protoplanetary disk and track the presolar dust inventory and its distribution.

Dr. Maria Lugaro is leading the Momentum “AGB Nuclei and Dust”  project of the Hungarian Academy  of Sciences in Budapest and holds an adjunct position as Senior Researcher of the Monash Centre for Astrophysics (Australia). Following a PhD from Monash University in 2001, she worked at the Institute of Astronomy in Cambridge (UK), as VENI fellow of the Netherland Organisation for Scientific Research (NWO) at the University of Utrecht, and as Australian Research Council (ARC) Future Fellow back at Monash University. Her research involves nuclear reactions in stars and the interpretation of their signatures in stellar spectra and meteoritic inclusion. In 2004 she authored the textbook on stardust “Stardust from meteorites: an introduction to presolar grains”   (World Scientific). Overall she authored or coauthored more than 40 works on the topic of stardust. She acknowledges the sup port and mentoring of Ernst Zinner all through her career and is particularly grateful for his encouragement during her PhD and help in revising the textbook, and for the many fun chats about life and politics.
