We present additional and revised IRAS diameters albedos for the 1992 Minor Planet Survey (IMPS). Using orbital elements 26,791 numbered asteroids, we found 2228 different multiply observed asteroids associated with sources, an increase of 432 (24%) over IMPS. The sample small D < 20.0 km, has increased by 72% (from 306 to 526), Jupiter Trojan 77% 39 69), (D 80 km) nearly a factor 3 nine 26). entire Supplemental data set, describe how it was created, compare IMPS estimate many more remain be in data.
Every three years the IAU/IAG Working Group on Cartographic Coordinates and Rotational Elements revises tables giving directions of poles rotation prime meridians planets, satellites, minor comets. This report introduces improved values for pole rate Pluto, Charon, Phoebe, Jupiter, sizes shapes Saturn satellites poles, rates, some planets A high precision realization Moon is provided. The expression Sun's has been changed to be consistent with account light travel time
Infrared photometry is reported for 22 Aten, Apollo, and Amor asteroids. Thermal models are used to derive the corresponding radiometric albedos diameters. Several of these asteroids appear have surfaces relatively high thermal inertia due exposure bare rock or a coarse regolith. The Apollo asteroid 3103, 1982 BB, recognized as class E. Jupiter-crossing 3552, 1983 SA, confirmed D, but low remain rare near-earth
Broadband U, V, and x photometry together with IRAS asteroid albedos have been used to construct an classification system. The system is based on three parameters (U-V v-x color indices visual geometric albedo), it able place 96 percent of the present sample 357 asteroids into 11 taxonomic classes. It noted that all but one these classes are analogous those previously found using other schemes. algorithm shown account for observational uncertainties in each parameters.
This chapter describes the contents and organization of IRAS Minor Planet Survey Data Base tells how to obtain hard-copy machine-readable versions data.
We present a new extensive analysis of the old problem finding satisfactory calibration relation between geometric albedo and some measurable polarization properties asteroids. To achieve our goals, we use all polarimetric data at disposal. For purposes calibration, limited sample objects for which can be confident to know with good accuracy, according previous investigations other authors. find set updated coefficients classical slope–albedo relation, but generalize consider also...
Compositionally diagnostic information regarding the spectral reflectance of faint asteroids and planetary satellites, obtained using a photometric system, is presented. Standard UBV range in effective wavelength from 0.34 to 1.04 microns are among eight broadband filters relative study. An InGaAsP photomultiplier high quantum efficiencies employed for longer wavelengths, allows work magnitude 17 fainter when used conjunction with 2 m telescope. Magnitudes color indices mean uncertainty + or...
We describe the creation of a model main asteroid belt whose purpose is to main-belt size frequency distribution and simulate number asteroids their fluxes at visual through mid-infrared (∼0.3–70 μm) wavelengths in any area sky for an arbitrary date. This based on population ∼1.9 × 106 obtained from complete known sample, plus extrapolation size-frequency distributions 15 dynamical families three background populations, diameter limit 1 km. The compared with data other models, example...
Abstract— We present Markov‐Chain Monte‐Carlo methods (MCMC) for the derivation of empirical model parameters photometric and polarimetric phase curves asteroids. Here we two jointly at angles ≤25° using a linear‐exponential model, accounting opposition effect in disk‐integrated brightness negative branch degree linear polarization. apply MCMC to V‐band asteroids 419 Aurelia (taxonomic class F), 24 Themis (C), 1 Ceres (G), 20 Massalia (S), 55 Pandora (M), 64 Angelina (E). show that can be...
