Asteroseismic measurement of the inclination angle: characterizing exoplanetary systems

open access: yes, 2021
Information on stellar inclinations are of prime importance to characterize the formation and dynamics of transiting exoplanetary systems, by helping to constrain the angle between the stellar spin axis and the planetary orbit axis, namely the obliquity.

Pressure distribution on a flat plate in the context of the phenomenon of the Coanda effect hysteresis

open access: yesScientific Reports, 2022
As a result of the Coanda effect, a symmetrical free jet will flow as an asymmetrical wall jet. At the same time, at the obstacle along which the flow is observed, the wall jet generates pressure distribution.
