Compact Ultradense Matter Impactors

We study interactions of meteorlike compact ultradense objects (CUDO), having nuclear or greater density, with Earth and other rocky bodies in the Solar System as a possible source of information about novel forms of matter. We study the energy loss in CUDO puncture of the body and discuss differences between regular matter and CUDO impacts.

The tidal fracture length scale $L$ from Eq. (4) normalized to the capture radius $R_c$ Eq. (5) as a function of distance from the trajectory. The velocity of the compact object is fixed at $v=40\mathrm{km}/\mathrm{s}$ and $c_s=8\mathrm{km}/\mathrm{s}$ used for the speed of sound in the mantle; a higher $v$ only reduces $L/R_c$.
