Astrochemistry and Planetary Science

The Savin Group is carrying out laboratory studies relevant to astrochemistry and planetary science. The student would most likely participate in both projects which involve experimental research and computer simulations of the relevant processes.

Apparatus for simulating key astrochemical processes along the cosmic cycle of gas.

The astrochemistry project is related to studies of key reactions which take place in the interstellar clouds and play important roles in the formation and evolution of stars and protoplanetary disks. Currently we focused on molecular N2 and CO reacting with H3+, using. our dual-source, merged-fast-beams apparatus pictured above.

Apparatus for simulation solar wind ion irradiation of airless planetary bodies.

The planetary science project involves laboratory work with our ion irradiation apparatus to simulate solar wind ion irradiation of airless planetary bodies, such as Mercury and the Moon. We measure the angular distribution of the resulting sputtering yields for analogs of planetary surfaces. The results help us to better understand the contribution of solar wind ion sputtering to the formation of planetary exospheres.

REU students working with the Savin Group would be based at Nevis Labs.
