Working models for the gravitational field of Phobos
Shi, Xian; Willner, Konrad; Oberst, Jürgen +2 more
Models for the gravitational field of Mars moon Phobos were developed using the latest shape model and assuming homogeneous density distribution. Three methods were applied in our study. Comparisons were made between these methods and all were shown to yield consistent results. Notably, the most accurate shape model of Phobos to date, complete up …
H α counterparts of X-ray bright points in the solar atmosphere
Zhang, Ping; Fang, Cheng; Zhang, QingMin
X-ray bright points (XBPs) are small-scale brightenings in the solar corona. Their counterparts in the lower atmosphere, however, are poorly investigated. In this paper, we study the counterparts of XBPs in the upper chromosphere where the Hα line center is formed. The XBPs were observed by the X-ray Telescope (XRT) aboard the Hinode spacecraft du…
Martian ionogram scaling by the Object Tracking Method
Ping, JinSong; Wang, MingYuan
The Mars Advanced Radar for Subsurface and Ionosphere Sounding (MARSIS) onboard the Mars Express (MEX) spacecraft started to collect data of the Martian topside ionosphere from May, 2005. By now a large amount of ionograms has been obtained. It is important to extract vertical ionospheric information effectively from the ionograms for further stud…
