Meteoritics &Planetary Science, Volume 58, Issue 3, Page 383-404, March 2023., 2023 Abstract Models of planetary core formation beginning with melting of Fe,Ni metal and troilite are not readily applicable to oxidized and sulfur‐rich chondrites containing only trace quantities of metal. Cores formed in these bodies must be dominated by sulfides.

Prussian Blue: Chemistry, Commerce, and Colour in Eighteenth‐Century Paris
Art History, Volume 46, Issue 1, Page 154-186, February 2023., 2023 This essay reconsiders the story of a pigment. Prussian blue, discovered at the beginning of the eighteenth century, is often described as a revolutionary colour that instantly transformed painters’ palettes and practices. Grounded in a ‘thick description’ of the pigment's history in Paris, this article challenges the legendary account of Prussian blue

Intrusive Magmatism Strongly Contributed to the Volatile Release Into the Atmosphere of Early Earth
Geochemistry, Geophysics, Geosystems, Volume 23, Issue 12, December 2022., 2022 Abstract Magmatic volatile release was crucial for the build‐up and composition of the early atmosphere and thus for the origin and evolution of life. Even though the rate of intrusive to extrusive magma production on Earth is high, intrusive volatile release is commonly neglected in studies modeling the composition of the early atmosphere.

Iron Hydride in the Earth's Inner Core and Its Geophysical Implications
Geochemistry, Geophysics, Geosystems, Volume 23, Issue 12, December 2022., 2022 Abstract Hydrogen is potentially a key light element in the Earth's core. Determining the stability of iron hydride is essential for Earth's core mineralogy applications. We investigated the thermal stabilities of a range of Fe‐H binaries at core P‐T conditions. It is concluded that face‐centered cubic phase FeH is stable in the Earth's inner core. The

Complex molecules in the Orion Kleinmann-Low nebula
BIO Web of Conferences, 2014 In the framework of the delivery to the early Earth of extraterrestrial molecules, we have studied complex molecular species toward the Orion Kleinmann-Low nebula. This nebula is rich in molecules as well as in nascent stars and planetary systems.

Near-infrared Circular Polarization Images of NGC 6334-V [PDF]
, 2013 We present results from deep imaging linear and circular polarimetry of the massive star-forming region NGC 6334-V. These observations show high degrees of circular polarization (CP), as much as 22% in the Ks band, in the infrared nebula associated with ...

Large Scale Flows from Orion-South [PDF]
, 2007 Multiple optical outflows are known to exist in the vicinity of the active star formation region called Orion-South (Orion-S). We have mapped the velocity of low ionization features in the brightest part of the Orion Nebula, including Orion-S, and imaged
