Charges in Planet Formation (CHIP)

research area: astrophysics

experiment title:

Charges in Planet Formation

experiment acronym: CHIP

funding agency: DLR

grant number: 50WM1762

performing organization:

Faculty of Physics, University of Duisburg-Essen

prime investigator:

Prof. Dr. Gerhard Wurm, Dr. Jens Teiser

experiment objective


Collisional charging within granular materials has a direct influence on the coagulation of grains to larger aggregates. To investigate the influence of electrical charge on the coagulation behavior within a granular gas is the objective of the payload. The coagulation behavior will be studied in three separate experiments, to analyze the influence of gas pressure and cosmic radiation on this process.
