TL;DR: Aluminum-magnesium isotopic analysis of plagioclase in the eucrite Piplia Kalan, with 27Al/24Mg ratio between 2000 to 7000, reveals the presence of excess magnesium-26 resulting from in situ decay of the short-lived nuclide aluminum-26, confirming aluminum- 26 as a plausible heat source for melting and differentiation of the eukrite parent body in particular and for planetesimals in general.

TL;DR: Bhandari et al. as discussed by the authors reported complementary analyses of Anjar outcrops by a joint Indo-French team, where they focused on cosmic markers (iridium and spinels) in the intertrappean sediments and 40Ar/39Ar dating and paleomagnetism of the lava flows.

TL;DR: In this article, track densities and spallation 22 Ne/21 Ne (NeR) ratios were used to determine the preatmospheric masses of meteorites. But the results of the analysis were limited.

TL;DR: In this paper, the authors measured the depth and size dependence of cosmogenic nuclides in ordinary chondrites for preatmospheric radii between 8.5 cm and about 100 cm, and the observed depth profiles and the dependence of the center production rates on meteoroid size were well reproduced by model calculations based on Monte Carlo calculations of the intra and internuclear cascade of galactic protons in meteoritic matter and on experimental and theoretical excitation functions of the underlying nuclear reactions.

TL;DR: In this paper, the assessment of physico-chemical parameters of water samples of Kosi river at Kosi sampling station during 2004 and 2005 in pre monsoon, monsoon and post monsoon seasons is presented.
