Thermal Properties of 1847 WISE-observed Asteroids
We present new thermophysical model fits of 1847 asteroids, deriving thermal inertia, diameter, and Bond and visible geometric albedo. We use thermal flux measurements obtained by the Wide-field
The Moon at thermal infrared wavelengths: a benchmark for asteroid thermal models
Thermal-infrared measurements of asteroids, satellites, and distant minor bodies are crucial for deriving the objects’ sizes, albedos, and in some cases, also the thermophysical properties of the
Shining Light on Thermophysical Near-Earth Asteroid Modeling Efforts
Comprehensive thermophysical analyses of Near-Earth Asteroids (NEAs) provide important information about their physical properties, including visible albedo, diameter, composition, and thermal
Determination of Size, Albedo, and Thermal Inertia of 10 Vesta Family Asteroids with WISE/NEOWISE Observations
In this work, we investigate the size, thermal inertia, surface roughness and geometric albedo of 10 Vesta family asteroids by using the Advanced Thermophysical Model (ATPM), based on the thermal
Analysis of Four-band WISE Observations of Asteroids
We analyzed 82,548 carefully curated observations of 4420 asteroids with Wide-field Infrared Survey Explorer (WISE) four-band data to produce estimates of diameters and infrared emissivities. We also
Revisiting the Advanced Thermal Physical Model: New Perspectives on Thermophysical Characteristics of (341843) 2008 EV5 from Four-band WISE Data with the Sunlight-reflection Model
In this paper, we investigate thermophysical characteristics of near-Earth asteroid (341843) 2008 EV5, based on our improved Advanced Thermal Physical Model (ATPM) by considering the contribution of
The Geometric Albedo of (4179) Toutatis Estimated from KMTNet DEEP-South Observations
We derive the geometric albedo of a near-Earth asteroid, (4179) Toutatis, to investigate its surface physical conditions. The asteroid has been studied rigorously not only via ground-based
Trans-Neptunian objects and Centaurs at thermal wavelengths


Surface Properties of Asteroids from Mid-Infrared Observations and Thermophysical Modeling
The subject of this work is the physical characterization of asteroids, focusing on the thermal inertia of near-Earth asteroids (NEAs). Thermal inertia governs the Yarkovsky effect, a
A Thermal Model for Near-Earth Asteroids
Abstract It has become common practice in studies of the thermal emission from near-Earth asteroids to employ thermal models developed on the basis of infrared observations of large, main-belt
Thermal Model Calibration for Minor Planets Observed with WISE/NEOWISE
With the Wide-field Infrared Survey Explorer (WISE; Wright et al. 2010), we have observed over 157,000 minor planets (Mainzer et al. 2011). Included in these are a number of near-Earth objects, Main
Thermal Tomography of Asteroid Surface Structure
Knowledge of the surface thermal inertia of an asteroid can provide insight into its surface structure: porous material has a lower thermal inertia than rock. We develop a means to estimate thermal
Comparing the NEATM with a Rotating, Cratered Thermophysical Asteroid Model
A cratered asteroid acts somewhat like a retroflector, sending light and infrared radiation back toward the Sun, while thermal inertia in a rotating asteroid causes the infrared radiation to peak
Investigation of Systematic Bias in Radiometric Diameter Determination of Near-Earth Asteroids: the Night Emission Simulated Thermal Model (NESTM)
The near-Earth asteroid thermal model (NEATM) has proven to be a reliable simple thermal model for radiometric diameter determination. However, NEATM assumes zero thermal emission on the night side
Thermal Model Calibration for Minor Planets Observed with Wide-field Infrared Survey Explorer/NEOWISE
With the Wide-field Infrared Survey Explorer (WISE), we have observed over 157,000 minor planets. Included in these are a number of near-Earth objects, main-belt asteroids, and irregular satellites
