Abstract

The goal of the project is to determine, through various methods, the ages for the target list of the Habitable Worlds Observatory (HWO), a new NASA space telescope project, to directly observe, for the first time, potentially habitable planets around nearby stars. Ages are fundametal, as biosignatures depend on the age of the system. However, this property has not yet been published for the initial target list of the HWO.
