Spitzer IRS Spectroscopy of the 10 Myr-old EF Cha Debris Disk: Evidence for Phyllosilicate-Rich Dust in the Terrestrial Zone [PDF]
, 2011 We describe Spitzer IRS spectroscopic observations of the 10 Myr-old star, EF Cha. Compositional modeling of the spectra from 5 {\mu}m to 35 {\mu}m confirms that it is surrounded by a luminous debris disk with LD/L\star ~ 10-3, containing dust with ...

Emergent 1/3 magnetization plateaus in pyroxene CoGeO_{3}
Physical Review Research, 2021 Despite the absence of an apparent triangular pattern in the crystal structure, we observe unusually well-pronounced 1/3 magnetization plateaus in the quasi-one-dimensional Ising spin chain compound CoGeO_{3} which belongs to the class of pyroxene ...

Anisotropy study of multiferroicity in the pyroxene NaFeGe2O6
New Journal of Physics, 2015 We present a study of the anisotropy of the dielectric, magnetic and magnetoelastic properties of the multiferroic clinopyroxene NaFeGe _2 O _6 . Pyroelectric currents, dielectric constants and magnetic susceptibilities as well as the thermal expansion ...

Olivine or Impact Melt: Nature of the "Orange" Material on Vesta from Dawn
, 2013 NASA's Dawn mission observed a great variety of colored terrains on asteroid (4) Vesta during its survey with the Framing Camera (FC). Here we present a detailed study of the orange material on Vesta, which was first observed in color ratio images ...

Deep Underground Science and Engineering, EarlyView.Cement infill shares compressive and shear stresses during loading, while interfacial friction hinders crack propagation and reduces stress concentration, improving the rock's load‐bearing capacity. Failure modes vary with crack inclination. Unfilled specimens show four modes.
