Seismological evidence for a localized mushy zone at the Earth’s inner core boundary
Nature Communications, 2017 The existence of a mushy zone in the Earth’s inner core has been suggested, but has remained unproven. Here, the authors have discovered a 4–8 km thick mushy zone at the inner core boundary beneath the Okhotsk Sea, indicating that there may be more ...

The Progenitor Dependence of the Preexplosion Neutrino Emission in Core-Collapse Supernovae [PDF]
, 2013 We perform spherically-symmetric general-relativistic simulations of core collapse and the postbounce preexplosion phase in 32 presupernova stellar models of solar metallicity with zero-age-main-sequence masses of 12 M_{sun} to 120 M_{sun}.

Core Phases and the Inner Core Boundary [PDF]
Geophysical Journal International, 1964 Summary A study is made of waves of short period and small amplitude arriving before and after P in the interval of 120°-155° by using 215 readings of 53 earthquakes as recorded by the Swedish seismological network from 1951 to 1962. Travel-time curves are determined for two phases PO and P1 preceding P up to 10–15 s and 6 s, respectively, also for ...

The Inner-Core Size Increase of Typhoon Megi (2010) During its Rapid Intensification Phase
Tropical Cyclone Research and Review, 2013 : While Typhoon Megi (2010) shared many common features of tropical cyclones (TCs) that crossed Luzon Island in northern Philippines, it experienced a significant inner-core size increase with little eyewall contraction during its rapid intensification ...

, 2008 A search for any particular feature in any single solar neutrino dataset is unlikely to establish variability of the solar neutrino flux since the count rates are very low.

The Anelasticity of the Inner Core [PDF]
Geophysical Journal International, 1974 Summary Spectral ratios of short-period core phases with common source and receiver and with nearly the same ray paths in the mantle have been formed to derive a Q-structure for 1 Hz compressional waves in the inner core. Data from one large array (NORSAR) have been used to extract the relevant phases, including the pairs (PKIKP, PKiKP), (PKIKP, PKP(

Pattern of Inner‐Core Differential Rotation From Long‐Term Earthquake Sequences and USArray Network
Geophysical Research LettersHow the differential rotation of the Earth's inner core (IC) has changed over time provides insights into the dynamics of the Earth's interior. Analyses of repeating earthquakes (doublets) have yielded different models.

Using Faraday Rotation Gradients to probe Magnetic Tower Models
, 2009 Parsec-scale multi-wavelength VLBA polarization observations can be used to study the magnetic-field structures of Active Galactic Nuclei (AGN) based on Faraday Rotation (FR) gradients. A number of transverse FR gradients have been found, and interpreted

Joint inversion for inner core rotation, inner core anisotropy, and mantle heterogeneity [PDF]
Journal of Geophysical Research: Solid Earth, 2000 Observational evidence for differential rotation of the inner core has recently been reported from time‐dependent travel times of the seismic inner core phase, PKP(DF). These analyses are hindered by potential biases from the mantle heterogeneity and systematic earthquake location errors, which have raised doubts about the reality of the inferred ...
