Extrasolar planets with WiFSIP
Since 2010, WiFSIP frequently observed transit events of extrasolar
planets. These observations yielded refined transit parameters, and
contributed to the search for additional planetary bodies in the systems
potentially revealed by transit timing variations. However, the main
science driver was an initial characterization of the planetary
atmospheres via broad-band spectrophotometry.
Additionally, WiFSIP provided complementary observations of the host
stars by long-term monitoring campaigns. The data were used to
accurately measure pulsation frequencies of a Delta-Scuti type host
star, and to estimate star spot parameters of several host stars with
rotationally modulated variability.
