A Subsolar Metallicity on the Ultra-short-period Planet HIP 65Ab by Luc Bazinet, Stefan Pelletier, Björn Benneke, Ricardo Salinas, Gregory N. Mace

“…Overall, our results are consistent with a sub-stellar metallicity but slightly elevated C/O. Such a composition may indicate that HIP 65Ab accreted its envelope from beyond the water snowline and underwent a disk-free migration to its current location. …”

Symmetry progression and possible polar metallicity in NiPS3 under pressure by Nathan C. Harms, Takahiro Matsuoka, Subhasis Samanta, Amanda J. Clune, Kevin A. Smith, Amanda V. Haglund, Erxi Feng, Huibo Cao, Jesse S. Smith, David G. Mandrus, Heung-Sik Kim, Zhenxian Liu, Janice L. Musfeldt

“…Even more strikingly, infrared spectroscopy and X-ray diffraction combined with a symmetry analysis reveal both metallicity and loss of the inversion center above ~23 GPa suggesting that NiPS3 may be a polar metal with a P3m1 space group under these conditions and P1 symmetry under maximum compression. …”

“…We examine the metallicity distribution function (MDF) and fraction of carbon-enhanced metal-poor (CEMP) stars in a sample that includes 86 stars with [Fe/H] ≤ –3.0, based on high-resolution, high signal-to-noise spectroscopy, of which some 32 objects lie below [Fe/H] = –3.5. …”

Single-walled carbon nanotubes metallicity discrimination via chemical force microscopy by Thong, Ya Xuan

“…Hence, little is known about the preferential affinity of various functional groups for the different SWNT metallicity. Therefore, by identifying functional groups that bind selectively to either the metallic or semiconducting SWNTs, it would aid in the total separation of SWNTs based on metallicity. …”
