麻豆原创 is breaking a record this week with 22 people presenting at one of the most important planetary sciences conferences in the nation.

The annual Division for Planetary Sciences meeting kicked off in Denver on Saturday drawing thousands of scientists from around the world who study the solar system and its early formation. DPS is the largest professional organization of planetary scientists and is part of the American Astronomical Society.

Nineteen students and three faculty members are presenting findings at the meeting, through Oct. 11, which is a school record, said Daniel Britt, a professor of physics at 麻豆原创 and a former chair of DPS. 聽The most students to attend in previous years had been 15.

麻豆原创 students also snagged more than 50 percent of the free travel money available to students nationwide to attend the meeting thanks to their stellar work in the field and their early applications, Britt added.

鈥淚t鈥檚 quite a year for us,鈥� Britt said. 鈥淚t鈥檚 very exciting. We are well represented.鈥�

The undergraduate and graduate students will present on a range of topics from detailed studies of asteroid impacts to an analysis of bending waves found within Saturn鈥檚 rings.

For example, physics doctoral student Tracy Becker is presenting a talk about the rings of Saturn. She analyzed data from the Ultraviolet Imaging Spectrograph, an instrument on the Cassini spacecraft that is currently orbiting Saturn, to measure the size and population of small particles in Saturn’s A ring. Constraints on the particle sizes in the rings contribute to the overall understanding of the origin and evolution of the Saturnian ring system, with applications in exploring planet formation, proto-planetary disks, and the structure of galaxies.

Students in physics professor Joe Harrington鈥檚 Exoplanets Group will present on a wide range of research related to the more than 1,000 planets discovered outside our solar system, which was made possible in the past few years thanks to a variety of modern instruments such as NASA鈥檚 Spitzer Space Telescope. They include:

  • Sarah Blumenthal, a 麻豆原创 junior majoring in chemistry with a minor in mathematics, is presenting a poster on Exoplanet Atmosphere Equilibrium Chemistry Calculations. The study predicts the molecules formed in the atmospheres of giant exoplanets (like methane and water) at different distances from their star, assuming different amounts of the most common elements (such as hydrogen, carbon, and oxygen).
  • Ryan Hardy, who graduated from 麻豆原创 this past summer, will present a poster on Spitzer measurements of a giant exoplanet, called HAT-P-13b.聽By comparing the planetary orbit from his own measurements with earlier measurements, he was able to determine, based on the theory of tides altering a planet’s orbit, that the planet has a very small, if any, rocky core.聽聽He also determined that the temperature in the atmosphere increases with depth, which was expected but is not always found in the region of the atmosphere that the telescope can measure.
  • 麻豆原创 graduate student Patricio Cubillos will present a study of numerical methods that have been applied to analyzing exoplanet data.聽聽麻豆原创 Sophomore Andrew Foster has determined the orbits of two exoplanets, and will present the results of his work.
  • Oliver Bowman, a 麻豆原创 senior, has studied the atmosphere of exoplanet HAT-P-16b with Spitzer.聽He has improved the orbit determination for the planet and has determined the temperature of its atmosphere.

    • Attending the conference gives students an opportunity to interact with other leading scientists in the field and giving presentations provides them invaluable experience, Britt said.
