Earth-sized planets around Trappist-1

February 24, 2017

The discovery of Earth-sized planets around Trappist-1 has been making waves, and we’re proud to say that the interior structures of those seven newly discovered planets were calculated based on the model developed here at EPS by the Jacobsen group. Attached is the paper from Nature that cites their work; specifically, figure 2 is plotted based on the composition model developed by Professor Stein Jacobsen, Professor Dimitar Sasselov of the Center for Astrophysics, and Dr. Li Zeng, Simons Foundation postdoc. They would like to thank the entire EPS community for their support, as… Read more about Earth-sized planets around Trappist-1

Isotope Geochemistry and Processes of Planetary Evolution

Professor Stein Jacobsen

2013 Dec 18

FAS Science Lecture - The Violent Origin of the Earth and Moon

7:00pm

Location: 

Science Center Hall C, 1 Oxford Street

Professor Sarah Stewart

The physical properties of our planet are intricately tied to the sequence of giant impact events that led to the formation of the Moon. The canonical giant impact model for lunar origin has been called into question by recent geochemical measurements of lunar rocks. Professor Stewart will present a new model for the origin of the Earth and Moon that reconciles the observations and highlights the importance of stochastic early events in shaping our habitable world.

Research Associate/Scientist
Jacobsen

Fatemeh Sedaghatpour has received her PhD in Space and Planetary Sciences from Arkansas Center for Space and Planetary Sciences at the University of Arkansas in 2013. She has joined Professor Stein Jacobsen’s group as a postdoctoral fellow in June 2013 and promoted to Research Associate in June 2016. Her research involves stable isotope cosmochemistry to study the early solar system, origin and evolution of planetary bodies. Her current research is focused on Mg and Ca stable isotope systems in lunar samples and meteorites samples using high precision isotopic analyses to have a better understanding of the Moon’s origin and evolution, and investigate the planetary formation processes.
