Abstract.
Visible-range absorption bands at 600–750 nm were recently detected on two
Edgeworth-Kuiper Belt (EKB) objects (Boehnhardt et al., 2002). Most probably the
spectral features may be attributed to hydrated silicates originated in the
bodies. We consider possibilities for silicate dressing and silicate aqueous
alteration within them. According to present models of the protoplanetary disk,
the temperatures and pressures at the EKB distances (30–50 AU) at the time of
formation of the EKB
objects (106 to 108 yr) were very low (15–30 K and 10−9–10−10 bar). At these
thermodynamic conditions all volatiles excluding hydrogen, helium and neon were
in the solid state. An initial mass fraction of silicates (silicates/(ices +
dust)) in EKB parent bodies may be estimated as 0.15–0.30.
Decay of the short-lived 26Al in the bodies at the early stage of their
evolution and their mutual collisions (at velocities ≥1.5 km s−1) at the
subsequent stage were probably two main sources of their heating, sufficient for
melting of water ice. Because of the former process, large EKB bodies (R ≥ 100
km) could contain a large amount of liquid water in their interiors for the
period of a few 106 yr. Freezing of the internal ocean might have begun at ≈ 5 ×
106 yr after formation of the solar nebula (and CAIs). As a result, aqueous
alteration of silicates in the bodies could occur.
A probable mechanism of silicate dressing was sedimentation of silicates with
refractory organics, resulting in accumulation of large silicate-rich cores.
Crushing and removing icy covers under collisions and exposing EKB bodies’
interiors with increased silicate content could facilitate detection of
phyllosilicate spectral features.

Abstract
—A preliminary study of the surface of the asteroid 21 Lutetia with ground-based methods is of significant importance, because this object is included into the Rosetta space mission schedule. From August 31 to November 20, 2000, about 50 spectra of Lutetia and the same number of spectra of the solar analog HD10307 (G2V) and regional standards were obtained with a resolution of 4 and 3 nm at the MTM-500 telescope television system of the Crimean astrophysical observatory. From these data, the synthetic magnitudes of the asteroid in the BRV color system have been obtained, the reflected light fluxes have been determined in absolute units, and its reflectance spectra have been calculated for a range of 370–740 nm. In addition, from the asteroid reflectance spectra obtained at different rotation phases, the values of the equivalent width of the most intensive absorption band centered at 430–440 nm and attributed to hydrosilicates of the serpentine type have been calculated. A frequency analysis of the values V (1, 0) confirmed the rotation period of Lutetia 0.d3405 (8.h172) and showed a two-humped light curve with a maximal amplitude of 0.m25. The color indices B–V and V–R showed no noticeable variations with this period. A frequency analysis of the equivalent widths of the absorption band of hydrosilicates near 430–440 nm points to the presence of many significant frequencies, mainly from 15 to 20 c/d (c/d is the number of cycles per day), which can be caused by a heterogeneous distribution of hydrated material on the surface of Lutetia. The sizes of these heterogeneities (or spots) on the asteroid surface have been estimated at 3–5 to 70 km with the most frequent value between 30 and 40 km.
