Visualizing Debris Disk "Roller Derby" to Understand Planetary System Evolution

Erika Nesvold

New work led by DTM’s Erika Nesvold looks at how a disk is affected by a planet that exists beyond its outermost edge and demonstrates that the disk’s shape can indicate whether the planet formed beyond the disk or initially existed inside of the disk and moved outward over time. The work is published in The Astrophysical Journal Letters.

Writing a Successful Grant Proposal

Joel Kastner

Joel Kastner, a professor at the Rochester Institute of Technology and DTM's most recent Merle A. Tuve Senior Fellow, led a workshop titled "Writing a Successful Grant Proposal" on Tuesday, March 7, 2017, in the Abelson Collaboration Center as part of DTM's Postdoctoral Development Workshop Series. 


Melting Temperature of Earth’s Mantle Depends on Water

Erik Hauri

A joint study between Carnegie and the Woods Hole Oceanographic Institution has determined that the average temperature of Earth’s mantle beneath ocean basins is about 110 degrees Fahrenheit (60 Celsius) higher than previously thought, due to water present in deep minerals. The results are published in Science.


Hunting for Giant Planet Analogs in our Own Backyard

Floating Planet

There may be a large number of undetected bright, substellar objects similar to giant exoplanets in our own solar neighborhood, according to new work from a team led by DTM’s Jonathan Gagné and including researchers from the Institute for Research on Exoplanets (iREx) at Université de Montréal. It is published by The Astrophysical Journal Supplement Series.


February 2017 Letter from the Director

Helene Le Mevel

Besides the record warmth we are enjoying in Washington this “winter”, something else unusual for DTM occurred in February - we hired a new staff scientist! We are very pleased to welcome Dr. Hélène Le Mével to the DTM geophysics group. Learn more about what research Le Mével will be doing at DTM in the February 2017 Letter from the Director.
