"One of the main questions in planetary astronomy is how did the solar system form, how did the planets form and then evolve," Gaulme said. "Jupiter is the most massive planet, it represents 70 percent of the mass in the solar system (apart from the sun). Giant planets like Jupiter or Saturn are mostly fluid (they contain no solid surface), which makes their seismology much closer to that of the sun than that of Earth. I started to work on the prototype of this instrument while doing my Ph.D.
"We are also going to study the wind circulation on Jupiter, Venus and Saturn. The circulation of planets is usually obtained by taking pictures of the planet and measuring the shift of clouds from one picture to the next, but clouds evolve constantly. It's not very accurate. With JIVE, we'd be able to measure the instantaneous speed of the clouds."
The JIVE instrument would measure Jovian oscillations and, for the first time, determine the interior structure and composition of Jupiter and Saturn to better understand their dynamic atmospheres. Researchers also will determine Jupiter's wind speeds and compare them to cloud-tracking results.
The goal of NASA EPSCoR is to provide funding to enable

Additionally, the grant will provide funding to employ three graduate students and two to six undergraduates. Students will be involved in all aspects of the project and will work alongside the PIs in the optics lab, computer lab and at the observatory after the instrument is installed.
Gaulme was part of a team of French researchers that developed the prototype of a similar device, the Doppler Spectro-Imager. The proposed device will be designed after DSI, with some modifications. Gaulme was a postdoctoral scholar of Jackiewicz's after completing his doctorate at
"Dr. Gaulme is the key member who brings years of planetary seismology expertise to the project, and with his strong collaboration with our French science partners,
Over the next six months, PIs will begin to hire students to assist in the project and collaborators will travel to
