# Seismic inference of 57 stars using full-length Kepler data sets

## TL;DR

This paper uses full-length Kepler data to infer detailed stellar properties for 57 stars, validating distances with Gaia data and exploring stellar parameter relationships.

## Contribution

It provides a comprehensive seismic analysis of 57 stars, deriving stellar properties and validating distance measurements, while establishing new relationships and regimes for stellar modeling.

## Key findings

- Validated Gaia-Tycho distances for the stars.
- Derived a linear relation between seismic parameter and stellar age.
- Identified regimes where empirical surface correction is valid.

## Abstract

We present stellar properties (mass, age, radius, distances) of 57 stars from a seismic inference using full-length data sets from Kepler. These stars comprise active stars, planet-hosts, solar-analogs, and binary systems. We validate the distances derived from the astrometric Gaia-Tycho solution. Ensemble analysis of the stellar properties reveals a trend of mixing-length parameter with the surface gravity and effective temperature. We derive a linear relationship with the seismic quantity $\langle r_{02} \rangle$ to estimate the stellar age. Finally, we define the stellar regimes where the Kjeldsen et al (2008) empirical surface correction for 1D model frequencies is valid.
