Timing and Origin of the Angrite Parent Body Inferred from Cr Isotopes

open access: yesAstrophysical Journal, 2019
Angrite meteorites are some of the oldest materials in the solar system. They provide important information on the earliest evolution of the solar system and accretion timescales of protoplanets.

Formation, Structure, and Detectability of the Geminids Meteoroid Stream

open access: yesThe Planetary Science Journal, 2023
The Geminids meteoroid stream produces one of the most intense meteor showers at Earth. It is an unusual stream in that its parent body is understood to be an asteroid, (3200) Phaethon, unlike most streams, which are formed via ongoing cometary activity.

Chromium Isotopic Constraints on the Origin of the Ureilite Parent Body

open access: yesAstrophysical Journal, 2019
We report on the mass-independent Cr isotope compositions of 11 main group ureilites and an ureilitic trachyandesite (ALM-A). The 54Cr/52Cr ratios for main group ureilites vary from −1.06 ± 0.04 to −0.78 ± 0.05 and averaged at −0.91 ± 0.15 (2SD, N = 18 ...

A large planetary body inferred from diamond inclusions in a ureilite meteorite

open access: yesNature Communications, 2018
Ureilites are a type of meteorite that are believed to be derived from a parent body that was impacted in the early solar system. Here, the authors analyse inclusions within diamonds from a ureilite meteorite and find that they must have formed at above ...

Testing accretion mechanisms of the H chondrite parent body utilizing nucleosynthetic anomalies

open access: yesMeteoritics and Planetary Science, 2019
Planetary bodies a few hundred kilometers in radii are the precursors to larger planets but it is unclear whether these bodies themselves formed very rapidly or accreted slowly over several millions of years.

Redistribution of Sr and rare earth elements in the matrices of CV3 carbonaceous chondrites during aqueous alteration in their parent body

open access: yesEarth, Planets and Space, 2018
We measured the abundances of Sr and rare earth elements (REEs) in the matrices of five CV3 carbonaceous chondrites: Meteorite Hills (MET) 00430, MET 01070, La Paz ice field (LAP) 02206, Asuka (A) 881317 and Roberts Massif (RBT) 04143.

Perturbative 2-body parent Hamiltonians for projected entangled pair states

open access: yesNew Journal of Physics, 2014
We construct parent Hamiltonians involving only local 2-body interactions for a broad class of projected entangled pair states (PEPS). Making use of perturbation gadget techniques, we define a perturbative Hamiltonian acting on the virtual PEPS space ...

Parent Involvement Intervention in Developing Weight Management Skills for both Parents and Overweight/Obese Children

open access: yesAsian Nursing Research, 2016
Purpose: The purpose of the study was to evaluate a parent involvement intervention for childhood obesity intended to increase parents' skills in managing children's weight-related behavior and to improve child-parent relationships. Many studies reported

Microbial mediation of textures and minerals – terrestrial or parent body processes?

open access: yesOpen Astronomy, 2019
Evolution of chondritic parent body is influenced by thermal, impact metamorphism and aqueous alteration, studied in Mező-Madaras, Knyahinya, Mócs and Nyírábrány in aspect of high resolution in situ textural, mineralogical and organic geochemical ...

Body dissatisfaction and low self-esteem in elementary school-aged children: the role of media pressure and trust in parent–child relationships

open access: yesFrontiers in Psychology
Studies have indicated that the media plays a role in the development of body dissatisfaction in children. Nevertheless, there is limited understanding of the protective factors that may reduce this association, such as the parent–child relationship ...
