    "description": "<p>Information on stellar inclinations are of prime importance to characterize the formation and dynamics of transiting exoplanetary&nbsp;systems, by helping to constrain the angle between the stellar spin axis and the planetary&nbsp;orbit axis, namely the&nbsp;obliquity. As PLATO will observe about 150 000 main-sequence stars potentially hosting&nbsp;exoplanets, it is crucial to have at hand a&nbsp;fast, robust and automated method to measure the stellar inclination angle.<br>\nI will present the method I developed and the results I derived for almost 1200 red giant stars that have been&nbsp;observed by the Kepler&nbsp;space mission, which exhibit mixed modes offering the opportunity to obtain accurate measurements of the inclination angle&nbsp;of the stellar rotation axis. I could characterize the biases affecting inclination&nbsp;measurements, in particular for extreme values&nbsp;close to 0 \u25e6 and 90 \u25e6 . This study allowed me to provide a way to infer&nbsp;the underlying statistical distribution of inclinations for a&nbsp;given sample of stars, free from observational limitations.&nbsp;This method has the advantage to be able to derive&nbsp;seismic&nbsp;measurements of the&nbsp;inclination angle for any solar-type&nbsp;pulsator with identified oscillation modes.</p>",
