Fig. 1.From: Collisional process on Comet 9/P Tempel 1: Mass loss of its dust and ice by impacts of asteroidal objects and its collisional historyR-plot against crater diameter for various exposure age T . Solid circles indicate the data observed on T1 (Thomas et al., 2007). Dash-dotted line indicates the empirical saturation line (R ∼ 0.2). Dashed-line indicates the R value for our sublimation erase model in Eq. (22).Back to article page
