Tuning Pulsation Modes with Stellar Interferometry

  • A. Domiciano de Souza (a1), F. Vakili (a1), S. Jankov (a1) and E. Janot-Pacheco (a2)

Abstract

Stellar interferometry represents a qualitative jump toward stellar surface imaging. We propose a method that tunes and filters out high degree non-radial pulsation (NRP) modes from the Fourier plane associated to the stellar brightness distribution. The proposed method can be applied to continuum flux, slow stellar rotation and high degree multi mode NRP stars.
