cds-question@unistra.frstellar-agesa-starsDEBRIS is a flux-limited survey of nearby stars (spectral types A-M) for evidence of debris disks with the Herschel Space Observatory. One goal of the survey is to determine disk incidence as a function of various stellar parameters. Understanding debris disk evolution depends on knowledge of the precise age of stars around which these debris disks are found. However, finding ages for field stars is notoriously difficult. Furthermore, in an unbiased sample like DEBRIS, one is working with stars across many spectral types. This requires a multi-method approach to age determination. In this paper, we outline several methods of age determination broken down by spectral type, including some strengths and limitations of each method. In total, we were able to calculate ages for 263 of 274 F-, G-, and K-type stars, and all 83 A-type stars in the DEBRIS sample.2012AJ....143..135Vhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/143/135CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toIX/10 : ROSAT All-Sky Bright Source Catalogue (1RXS) (Voges+ 1999)I/239 : The Hipparcos and Tycho Catalogues (ESA 1997)III/159 : CaII H and K Measurements Made at MWO (Duncan+ 1991)J/ApJ/756/133 : ScoCen debris disks around B- and A-type stars (Chen+, 2012)J/ApJ/743/48 : Stellar rotation periods & Xray luminosities (Wright+, 2011)J/ApJ/738/122 : ScoCen debris disks Around F- and G-type stars (Chen+, 2011)J/MNRAS/403/1089 : SUNS and DEBRIS surveys target selection (Phillips+, 2010)J/A+A/493/1099 : Ca2 HK emission in rapidly rotating stars (Schroeder+, 2009)J/MNRAS/387/105 : Isochrone database for single & binary-star SSPs (Li+, 2008)J/ApJ/687/1264 : Age estimation for solar-type dwarfs (Mamajek+, 2008)J/ApJ/660/1556 : Characterization of dusty debris disks (Rhee+, 2007)J/PASJ/59/335 : Properties of 160 F-K disk dwarfs/subgiants (Takeda+, 2007)J/AJ/132/161 : NStars project: The southern sample.
