isochrone Archives

Distribution of stellar isochrone mass (top) and spectroscopic metallicity (bottom) with isochrone (left) and gyrochronology (right) ages where the colour indicates the number of data points in each bin, with equal number of bins across the four distributions. These distributions illustrate that the two samples of isochrone and gyrochronology ages span a different parameters space in mass and metallicity despite sharing the same stars. It also shows the relationship between mass and metallicity with age which could bias the trend between occurrence rate and age. -- astro-ph.EP

Exoplanet Occurrence Rate with Age for FGK Stars in Kepler

by Keith CowingJanuary 24, 2025January 24, 2025

We measure exoplanet occurrence rate as a function of isochrone and gyrochronology ages using confirmed and candidate planets identified in Q1-17 DR25 Kepler data.
