NanoSIMS analysis of organic carbon from the Tissint Martian meteorite: Evidence for the past existence of subsurface organic-bearing fluids on Mars
Yangting Lin,Ahmed El Goresy,Sen Hu,Jianchao Zhang,Philippe Gillet,Y. Xu,Jialong Hao,Masaaki Miyahara,Ziyuan Ouyang,Eiji Ohtani,Lin Xu,Wei Yang,L. Feng,Xuchao Zhao,Jing Yang,Shin Ozawa +15 more
TL;DR: Two petrographic settings of carbonaceous components, mainly filling open fractures and occasionally enclosed in shock-melt veins, were found in the recently fallen Tissint Martian meteorite as mentioned in this paper.

Journal ArticleDOI
Murchison presolar carbon grains of different density fractions: A Raman spectroscopic perspective
TL;DR: In this paper, Raman analysis of presolar graphite grains from three different density fractions of the Murchison meteorite has been performed, and the results show that the high-density fraction KFA1 (2.05-2.20 g/cm3) has a very strong 2nd-order peak characteristic of graphite and the low density fraction KFB1 has an amorphous graphite.
Journal ArticleDOI
Sulfur Isotopic Compositions of Submicrometer SiC Grains from the Murchison Meteorite
TL;DR: In this article, the authors reported C, Si, N, S, Mg-Al, and Ca-Ti isotopic compositions of presolar silicon carbide (SiC) grains from the SiC-rich KJE size fraction (0.5-0.8μm) of the Murchison meteorite.
Journal ArticleDOI
Early phase of massive star formation: a case study of the infrared dark cloud g084.81–01.09
TL;DR: In this article, the Mid-course Space Experiment dark cloud G084.81-01.09 was mapped in the NH(3)(1, 1, 1)-(4, 4) lines and in the J = 1-0 transitions of (12)CO, (13) CO, C(18)O, and HCO(+) in order to study the physical properties of infrared dark clouds and to better understand the initial conditions for massive star formation.
