Astrophysics Colloquium

Submillimeter Wave Heterodyne Observation of the Solar System
Presented by Paul Hartogh
Max Planck Institute for Solar System Research, Göttingen, Germany

Thursday, June 27, 2019
11:00 A.M. in 169-336

Abstract
Herschel-HIFI, with its unprecedented sensitivity in the far infrared wavelengths range, has provided exciting new insights into solar system science, addressing topics such as the origin and formation of the solar system, the water cycle of Mars, the source of water in the stratospheres of the outer planets, the isotopic ratios in cometary and planetary atmospheres and a number of new detections, including the Enceladus water torus, water atmospheres and emissions of the Galilean satellites and Ceres and the ocean like water in Jupiter family comets. Most of these kinds of observations can only be performed in the submillimeter wave range and from space. After a review of the Herschel results and some SOFIA findings the presentation will focus on the prospectives in solar system science of potential new space telescopes and the Submillimeter Wave Instrument on JUICE.
