cds-question@unistra.frgamma-ray-astronomygamma-ray-burstsx-ray-sourcesredshiftedGamma-ray bursts (GRBs) can be divided into three subclasses: X-ray flash (XRF), X-ray rich (XRR), and classical GRB (C-GRB). An X-ray flare is the rebrightening emission shown in the early X-ray afterglow of some GRBs. In this paper, we comprehensively examine the X-ray flare properties among XRF, XRR, and C-GRB subclasses. We utilize the XRF, XRR, and C-GRB subclass samples obtained from the Swift-BAT3 catalog, and the X-ray flare observational properties are collected from Falcone+ (2007ApJ...671.1921F), Chincarini+ (2010MNRAS.406.2113C), and Yi+ (2016, J/ApJS/224/20). We find that XRFs and XRRs have more bright X-ray flares than C-GRBs. The ratio of the X-ray flare fluence to the prompt emission fluence has different distributions between XRF and C-GRB subclasses. The linear correlation between the duration and the peak time of the X-ray flares is also different between XRF and C-GRB subclasses. We are inclined to identify the GRBs with the bright X-ray flares as XRFs or XRRs. We discuss some issues that are related to the XRF/XRR/C-GRB classification. We also caution the selection effects and the instrument bias in our investigation. Large samples are required in the future to further confirm our results.2019ApJ...884...59Lhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/884/59CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toB/swift : Swift Master Catalog (HEASARC, 2004-)J/ApJS/126/19 : BATSE gamma-ray burst spectral catalog.
