Scaling slowly rotating asteroids by stellar occultations
A. Marciniak, J. Äurech, A. Choukroun +176
As evidenced by recent survey results, majority of asteroids are slow rotators (P>12 h), but lack spin and shape models due to selection bias. This bias is skewing our overall unde…
Relationship between local hydride ion dynamics and ionic conductivity in LaHO inferred from muon study
M. Hiraishi, S. Takeshita, H. Okabe +6
We performed muon spin rotation and relaxation (SR) experiments to investigate the microscopic mechanism behind the high ionic conductivity () exhibited by hydride (H)…
Citizen Science Astronomy with a Network of Small Telescope: The Launch and Deployment of JWST
R. A. Lambert, F. Marchis, F. +54
We present a coordinated campaign of observations to monitor the brightness of the James Webb Space Telescope (JWST) as it travels toward the second Earth-Sun Lagrange point and un…
Magnetic circular dichroism of x-ray absorption spectroscopy at rare-earth L2,3 edges in RE2Fe14B compounds (RE = La, Pr, Nd, Sm, Gd, Tb, Dy, Ho, Er, Tm, Yb, and Lu)
K. Fukui, H. Ogasawara, A. Kotani +6
Magnetic circular dichroism (MCD) in the x-ray absorption spectroscopy (XAS) at the L2,3 edges for almost entire series of rare-earth (RE) elements in RE2Fe14B, is studied experime…
Constraints on Triton atmospheric evolution from occultations: 1989-2022
B. Sicardy, A. Tej, A. R. Gomes-Junior +49
Context - Around the year 2000, Triton's south pole experienced an extreme summer solstice that occurs every about 650 years, when the subsolar latitude reached about 50°. Bracket…
Photogenerated Carriers in SrTiO3 Probed by Mid-Infrared Absorption
H. Okamura, M. Matsubara, K. Tanaka +6
Infrared absorption spectra of SrTiO have been measured under above-band-gap photoexcitations to study the properties of photogenerated carriers, which should play important ro…
