Science & Technology Policy Fellowships: A Bridge Between Academia and Congress

Science Policy Workshop

Caitlin Murphy, a 2012-2014 Geophysical Laboratory Postdoctoral Fellow who received her Ph.D. from Caltech, presented a talk about her experience as an AIP-ASA Congressional Science Fellow in the United States Senate. 

Murphy's science policy fellowship included working on Climate Change policy, the Keystone XL pipeline, and a broad energy bill that was crafted by the Senate Energy Committee. These experiences allowed her to help shape the discussion about how to advance progressive, clean energy policy, which sends important market signals to the innovators, manufacturers, and distributors of clean energy technologies.

What Kinds of Stars Form Rocky Planets?

Kepler-62f

As astronomers continue to find more and more planets around stars beyond our own Sun, they are trying to discover patterns and features that indicate what types of planets are likely to form around different kinds of stars. This will hopefully inform and make more efficient the ongoing planet hunting process, and also help us better understand our own Solar System’s formation.

New work from a team including Johanna Teske, Origins fellow at DTM and The Observatories, extended this idea by measuring a large suite of elements besides iron. They found that stars with Earth-sized rocky planets are overall chemically similar to those with Neptune-sized planets, and to stars with no planets, but not to stars with gas giant planets.
