Identification of Pulsation Modes in Main Sequence Stars: Potentials and Limits

TL;DR

This paper reviews current methods for identifying pulsation modes in main sequence stars using multicolour photometry and radial velocity data, discussing their potentials, limitations, and challenges in high degree mode identification.

Contribution

It provides a comprehensive overview of existing mode identification techniques and discusses the challenges in detecting high degree modes with space-based observations.

Findings

Current methods effectively identify low degree modes.

High degree mode identification remains challenging with space data.

Diagnostic properties are affected by various observational and stellar factors.

Abstract

We review the present-day methods of mode identification applied to main sequence pulsators focusing on those that make use of multicolour photometry and radial velocity data. The effects which may affect diagnostic properties of these observables are discussed. We also raise the problem of identification of high degree modes which can dominate oscillation spectra obtained from space-based projects.
