Evidence of sub-surface energy storage in comet 67P from the outburst of 2016 July 3
J. Agarwal, V. Della Corte, P. D. Feldman +67
On 3 July 2016, several instruments on board ESA's Rosetta spacecraft detected signs of an outburst event on comet 67P, at a heliocentric distance of 3.32 AU from the sun, outbound…
Thermophysical characteristics of the large main-belt asteroid (349) Dembowska
LiangLiang Yu, Bin Yang, Jianghui Ji +1
(349) Dembowska, a large, bright main-belt asteroid, has a fast rotation and oblique spin axis. It may have experienced partial melting and differentiation. We constrain Dembowska'…
The highly active Anhur-Bes regions in the 67P/Churyumov - Gerasimenko comet: results from OSIRIS/ROSETTA observations
S. Fornasier, C. Feller, J. C. Lee +51
The Southern hemisphere of the 67P/Churyumov-Gerasimenko comet has become visible from Rosetta only since March 2015. It was illuminated during the perihelion passage and therefore…
Distance determination method of dust particles using Rosetta OSIRIS NAC and WAC data
E. Drolshagen, T. Ott, D. Koschny +42
The ESA Rosetta spacecraft has been tracking its target, the Jupiter-family comet 67P/Churyumov-Gerasimenko, in close vicinity for over two years. It hosts the OSIRIS instruments:…
Confirmation of Large Super-Fast Rotator (144977) 2005 EC127
Chan-Kao Chang, Hsing-Wen Lin, Wing-Huen Ip +7
(144977) 2005 EC127 is an V-/A-type inner-main-belt asteroid with a diameter of 0.6 +- 0.1 km. Asteroids of this size are believed to have rubble-pile structure, and, therefore, ca…
Surface thermophysical properties investigation of the potentially hazardous asteroid (99942) Apophis
LiangLiang Yu, Jianghui Ji, Wing-Huen Ip
In this work, we investigate the surface thermophysical properties (thermal emissivity, thermal inertia, roughness fraction and geometric albedo) of asteroid (99942) Apophis, using…
