Probe the regolith characteristics of asteroids from 9-years infrared observations of WISE/NEOWISE: A case study of the Main-Belt Object (656) Beagle
Liang-Liang Yu
This work presents data processing, fitting procedure, modelling and analyzing of 9-years infrared light curves provided by the WISE/NEOWISE telescope, by which the regolith charac…
Active Asteroid 311P/PANSTARRS: Rotational Instability as the Origin of Multi-tails?
Bin Liu, Xiaodong Liu, Xiaoyu Jia +3
The active asteroid 311P is one of the two targets of a planned Chinese asteroid exploration mission Tianwen-2. During 2013, 311P experienced several mass-loss events and exhibited…
Mid-IR Observations of IRAS, AKARI, WISE/NEOWISE and Subaru for Large Icy Asteroid (704) Interamnia: a New Perspective of Regolith Properties and Water Ice Fraction
Haoxuan Jiang, Jianghui Ji, Liangliang Yu +3
(704) Interamnia is one of the largest asteroids that locates in the outer main-belt region, which may contain a large amount of water ice underneath its surface. We observe this a…
Determination of size, albedo and thermal inertia of 10 Vesta family asteroids with WISE/NEOWISE observations
Haoxuan Jiang, Jianghui Ji, Liangliang Yu
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…
Low activity main belt comet 133P/Elst-Pizarro: New constraints on its Albedo, Temperature and Active Mechanism from a thermophysical perspective
Liang Liang Yu, Chih-Hao Hsia, Wing-Huen Ip
133P/Elst-Pizarro is the firstly recognized main-belt comet, but we still know little about its nucleus. Firstly we use mid-infrared data of Spitzer-MIPS, Spitzer-IRS and WISE to e…
Revisiting Advanced Thermal Physical Model: New Perspectives on Thermophysical Characteristics of (341843) 2008 EV5 from Four-bands WISE Data with Sunlight-Reflection Model
Haoxuan Jiang, Liangliang Yu, Jianghui Ji
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 t…
What mechanisms dominate the activity of Geminid Parent (3200) Phaethon?
LiangLiang Yu, Wing-Huen Ip, Tilman Spohn
A long-term sublimation model to explain how Phaethon could provide the Geminid stream is proposed. We find that it would take Myr or more for Phaethon to lose all of its i…
