Meteorite spectroscopy and characterization of asteroid surface materials [PDF]
The analysis of visible and near-infrared reflectance spectra is the primary means to determine surface mineralogy and petrology of individual asteroids.

Eos, Transactions American Geophysical Union, 1971 Review Articles and Meetings. I will concentrate on recent review articles, especially when they give titles of earlier papers. Only for asteroids, because there seems to be no published review, and for other selected topics will we go back more than 4 years.

Meteoritics &Planetary Science, EarlyView.Abstract We reevaluated pairing relationships among 56 Antarctic howardites, eucrites, and diogenites (HED) from the Miller Range ice fields (MIL) based on new measurements of cosmogenic radionuclides and bulk composition of 28 HED samples and one HED‐related dunite.

Evidence for the Effects of Space Weathering Spectral Signatures on Low Albedo Asteroids
, 2013 Context. Space weathering changes asteroid surfaces. We know from observations of the Moon and high-albedo asteroids that interplanetary surface processes can alter the spectral properties of silicates.

Active Asteroids: Main-Belt Comets and Disrupted Asteroids [PDF]
arXiv, 2015 The study of active asteroids has attracted a great deal of interest in recent years since the recognition of main-belt comets (which orbit in the main asteroid belt, but exhibit comet-like activity due to the sublimation of volatile ices) as a new class of comets in 2006, and the discovery of the first disrupted asteroids (which, unlike MBCs, exhibit ...

Meteoritics &Planetary Science, EarlyView.Abstract We report the discovery of (Al,Cu)‐bearing metallic alloys in two micrometeorites found in the Project Stardust collection gathered from urban rooftop environments in Norway. Most of the alloys are the same as those found in the Khatyrka meteorite and other micrometeorites, though one has a composition that has not been reported previously ...

Expected value, to a point: Moral decision‐making under background uncertainty
Noûs, EarlyView.Abstract Expected value maximization gives plausible guidance for moral decision‐making under uncertainty in many situations. But it has unappetizing implications in ‘Pascalian’ situations involving tiny probabilities of extreme outcomes. This paper shows, first, that under realistic levels of ‘background uncertainty’ about sources of value independent

AcuA: the AKARI/IRC Mid-infrared Asteroid Survey [PDF]
PASJ, 2011, Vol.63, No.5, pp.1117-1138, 2011 We present the results of an unbiased asteroid survey in the mid-infrared wavelength with the Infrared Camera (IRC) onboard the Japanese infrared satellite AKARI. About 20% of the point source events recorded in the AKARI All-Sky Survey observations are not used for the IRC Point Source Catalog (IRC-PSC) in its production process because of the lack of
