Global helioseismology (WP4.1): From the Sun to the stars & solar analogs

TL;DR

This paper reviews the SPACEINN global helioseismology team's recent activities, focusing on stellar surface dynamics, magnetic properties, and seismic analysis of solar analogs to contextualize the Sun among similar stars.

Contribution

It introduces new seismic data and metrics for surface dynamics and magnetic properties of solar-like stars, enhancing understanding of the Sun's place among stellar counterparts.

Findings

Characterized rotation and magnetic properties of ~300 solar-like stars

Analyzed surface magnetic and seismic properties of 18 solar analogs

Provided new seismic data and metrics via the SPACEINN portal

Abstract

Sun-as-a star observations put our star as a reference for stellar observations. Here, I review the activities in which the SPACEINN global seismology team (Working Package WP4.1) has worked during the past 3 years. In particular, we will explain the new deliverables available on the SPACEINN seismic+ portal. Moreover, special attention will be given to surface dynamics (rotation and magnetic fields). After characterizing the rotation and the magnetic properties of around 300 solar-like stars and defining proper metrics for that, we use their seismic properties to characterize 18 solar analogues for which we study their surface magnetic and seismic properties. This allows us to put the Sun into context compared to its siblings.
