Magnetically controlled ionosphere of Mars: A model analysis with the vertical plasma drift effects
Haider, S. A.; Bougher, S. W.; Withers, P. +2 more
We use our 1-D chemical diffusive model to quantify the physical processes necessary to interpret the dayside ionospheric electron density profiles measured with the Mars Radio Science (MaRS) experiment onboard the Mars Express (MEX) and Radio Occultation Science Experiment (ROSE) onboard the Mars Atmosphere and Volatile Evolution (MAVEN) spacecra…
The variability of the topside ionospheres of Venus and Mars as seen by recent radio science observations
Fränz, Markus; Tellmann, Silvia; Pätzold, Martin +7 more
This study combines the observations of the Venus Express Venus Radio science experiment (VeRa), Mars Express Mars Radio Science experiment (MaRS), and MAVEN Radio Occultation Science Experiment (ROSE) at Venus and Mars with proxies for environmental parameters, insolation and solar wind characteristics to compare the effects of individual drivers…
Short-wave fadeout on mars: Radio absorption in the dayside martian ionosphere enhanced by solar flares
Lester, M.; Sánchez-Cano, B.; Harada, Y. +1 more
Solar flares can cause radio absorption in the D region of the Earth's ionosphere and consequently interrupt high-frequency radio communication systems, also known as short-wave fadeout or the Dellinger effect. We present an analogous radio absorption event observed at Mars during a solar flare. In this event, the Mars Express Mars Advanced Radar …
Astrometric observations of Phoebe from 2010 to 2019 based on Gaia DR3
Cheng, X.; Zhang, H. Y.; Yan, D. +2 more
A total of 914 positions of Phoebe were collected from 2010 to 2019 with three different telescopes, which were the 1.56 m telescope at the Sheshan station of Shanghai Astronomical Observatory, the 1.0 m telescope at the Kunming station of Yunnan Astronomical Observatory and the 2.4 m telescope at the Lijiang station of Yunnan Astronomical Observa…
