Identification of Magnetite in B-type Asteroids

  journal={The Astronomical Journal},
Spectrally blue (B-type) asteroids are rare, with the second discovered asteroid, Pallas, being the largest and most famous example. We conducted a focused, infrared spectroscopic survey of B-type asteroids to search for water-related features in these objects. Our results show that the negative optical spectral slope of some B-type asteroids is due to the presence of a broad absorption band centered near 1.0 μm. The 1 μm band can be matched in position and shape using magnetite (Fe3O4), which… Expand

Follow-up observations for the Asteroid Catalog using AKARI Spectroscopic Observations
In the 1-2.5 micron range, spectroscopic observations are made on the AcuA-spec asteroids, whose spectra were obtained in a continuous covered mode between 2.5-5.0 micron by AKARI. Based on theExpand
Primitive, outer-belt asteroids are generally of low albedo, reflecting carbonaceous compositions like those of CI and CM meteorites. However, a few outer-belt asteroids having high albedos areExpand
Most outer main-belt asteroids have low albedos because of their carbonaceouslike bodies. However, infrared satellite surveys have revealed that some asteroids have high albedos, which may suggestExpand
Toward an understanding of phyllosilicate mineralogy in the outer main asteroid belt
Abstract Proposed mineralogical linkages between CM/CI carbonaceous chondrites and outer Main Belt asteroids remain uncertain due to a dearth of diagnostic absorptions in visible and near-infraredExpand
Portrait of the Polana–Eulalia family complex: Surface homogeneity revealed from near-infrared spectroscopy
Abstract The inner asteroid belt is an important source of near-Earth asteroids (NEAs). Dynamical studies of the inner asteroid belt have identified several families overlapping in proper orbitalExpand
First Satellite to a B-type Asteroid, (702) Alauda: Dynamical Mass and Density
Observations with the adaptive optics system on the Very Large Telescope reveal that the outer main belt asteroid (702) Alauda has a small satellite with primary to secondary diameter ratio of 56.Expand
Almahata Sitta (=asteroid 2008 TC3) and the search for the ureilite parent body
Abstract– This article explores what the recovery of 2008 TC3 in the form of the Almahata Sitta meteorites may tell us about the source region of ureilites in the main asteroid belt. An investigationExpand
Outer Main Belt asteroids: Identification and distribution of four 3-μm spectral groups
Abstract This paper examines the distribution and the abundance of hydrated minerals (any mineral that contains H 2 O or OH) on outer Main Belt asteroids spanning the 2.5  a a a a a 2 O ice. AExpand
Spectrally blue hydrated parent body of asteroid (162173) Ryugu
It is reported that spectrally blue Ryugu’s parent body experienced intensive aqueous alteration and subsequent thermal metamorphism at 570–670 K (300–400 °C), suggesting that Ryugu's parent body was heated by radioactive decay of short-lived radionuclides possibly because of its early formation 2–2.5 Ma.

Origins of colors variability among C-cluster main-belt asteroids
The Sloan Digital Sky Survey provides colors for more than 100 000 moving objects, among which around 10 000 have albedos determined. Here we combined colors and albedo in order to perform a clusterExpand


Spectroscopy of B-type Asteroids: Subgroups and meteorite analogs
[1] B-type asteroids have a negative slope from -0.5 to ∼1.1 μm and beyond. What causes this? Visible to near-infrared reflectance spectra (0.4-2.5 μm) are assembled for 22 B-type asteroids. TheExpand
The composition and origin of the C, P, and D asteroids: Water as a tracer of thermal evolution in the outer belt
Abstract We present results of an extensive laboratory and telescopic investigation of H 2 O distribution among the low-albedo, outer belt asteroids (2.5–5.2 AU). The water distribution wasExpand

Detection of ice and organics on an asteroidal surface
The spectroscopic detection of water ice and organic material on the asteroid 24 Themis is reported, a detection that has been independently confirmed and concludes that water ice is more common on asteroids than was previous thought and may be widespread in asteroidal interiors at much smaller heliocentric distances than was previously expected.
