A ballistics analysis of the Deep Impact ejecta plume: Determining Comet Tempel 1's gravity, mass, and density (2007, methodology): “Due to the self-similarity of all gravity-dominated craters, the proportionality constant C T g is invariant across both similar and non-similar impacts, and has an experimentally determined value of 0.8–0.9 (Schmidt and Housen, 1987; Holsapple and Housen, 2007).”
A NEW CHRONOLOGY FOR THE MOON AND MERCURY (2008, unknown): “The first one by Holsapple & Housen (2007) (H&H hereinafter), reads: D = kd [ gd 2v2 ⊥ ( ρ δ ) 2ν µ + ( Y ρv2 ⊥ ) 2+µ 2 ( ρ δ ) ν(2+µ) µ ]− µ 2+µ (4) where g is the target gravitational acceleration, v⊥ is the perpendicular component of the impactor velocity, δ is the projectile density, ρ and Y…”
AIDA DART asteroid deflection test: Planetary defense and science objectives (2018, background): “If the ejecta consist of much smaller-sized dust, as was the case with the Deep Impact mission at comet Tempel 1 (Holsapple and Housen, 2007), then the ejecta probably will not be detectable with radar.”
Nonuniform cratering of the Moon and a revised crater chronology of the inner Solar System (2011, methodology): “We use a linear transition from porous (i.e., ”sand or co-19 hesive soils” from Holsapple and Housen (2007)) to nonporous scaling to fit20 either the Neukum or Hartmann production functions.”
Nonuniform cratering of the terrestrial planets (2008, background): “For non porous rocks, the adopted scaling constants are K = 1.17, ν1 = 0.22 and ν2 = 0.31, whereas for dry sand K � = 1.03, ν�1 = 0.17 and ν�2 = 0.332 (Schmidt and Housen, 1987; Holsapple and Housen, 2007 ).”
The timeline of the lunar bombardment: Revisited (2018, methodology): “14 km/s for Mars, with an impact angle of 45 degrees. For reference, the relationship D crater = 10D impactor is also plotted. We use the scaling law between projectile size and crater size given in (Holsapple and Housen, 2007), which is very similar to that in Johnson et al. (2016). These scaling l”
