An Etymological Dictionary of Astronomy and Astrophysics

An open-source (adiabatic/non-adiabatic) pulsation code that calculates the oscillation frequencies of an input stellar model. The code is based on a “Magnus Multiple Shooting” scheme, which is a numerical technique to solve boundary value problems. This is done by subdividing the possible solution space into sub-intervals and solving the pulsation equation in these sub-intervals, assuming continuity conditions. GYRE is integrated into → Modules for Experiments in Stellar Astrophysics (MESA)’s → asteroseismologic module (Townsend & Teitler, 2013, MNRAS 435, 3406).
