Caustics of wave fronts reflected by a surface

open access: yesJournal of Mathematical Sciences and Modelling, 2018
One can often see caustic by reflection in nature but it is rather hard to understand the way of how caustic arise and which geometric properties of a mirror surface define geometry of the caustic.

Does the Second Caustic Ring of Dark Matter Cause the Monoceros Ring of Stars ? [PDF]

open access: yes, 2007
Caustic rings of dark matter were predicted to exist in the plane of the Galaxy at radii $a_n \simeq 40 {\rm kpc}/n$ for $n = 1,2,3 ..$. The recently discovered Monoceros Ring of stars is located near the $n=2$ caustic, prompting us to consider a ...

Properties of the Planetary Caustic Perturbation [PDF]

open access: yes, 2010
Just two of 10 extrasolar planets found by microlensing have been detected by the planetary caustic despite the higher probability of planet detection relative to the central caustic which has been responsible for four extrasolar planet detections.

Caustic ingestions

open access: yesMedicina, 2009
Caustic ingestions (alkalis, acids) may cause severe chemical burns and lifelong complications, which worsen life quality. Approximately 80% of caustic ingestions occur in children. They mostly intoxicate because of chemical substances kept insecurely or in inappropriate containers.

Experimental study on impact fracture of cantilever beam-column specimen with prefabricated crack

open access: yes矿业科学学报, 2018
The impact fracture mechanics of the cantilever beam-column specimens with different inclination angles(0°,30°,60°) prefabricated cracks subjected to hammer impact loading were studied by using digital dynamic caustic test system.The results show that ...

Event Horizon Deformations in Extreme Mass-Ratio Black Hole Mergers [PDF]

open access: yes, 2011
We study the geometry of the event horizon of a spacetime in which a small compact object plunges into a large Schwarzschild black hole. We first use the Regge-Wheeler and Zerilli formalisms to calculate the metric perturbations induced by this small ...

Beyond Caustic Crossings: Properties of Binary Microlensing Light Curves [PDF]

open access: yes, 2007
Binary microlensing light curves have a variety of morphologies. Many are indistinguishable from point lens light curves. Of those that deviate from the point lens form, caustic crossing light curves have tended to dominate identified binary lens events.
