2018年11月1日 · Solar wind-driven atmospheric ion escape has long been hypothesized as a major influence on the evolution of the Martian atmosphere due to the lack of a Martian global …

2023年3月15日 · Ion escape from Mars over a time period covering two deep solar minima is presented. The ion escape is clearly modulated by the solar activity, being up to three times …

the ion escape rates are within 40% of the MAVEN results. The ion escape rate is found to vary linearly with the solar wind speed. Using the simulation results to scale the MAVEN ion escape …

2006年6月1日 · We have analysed ion escape at Mars by comparing ASPERA-3/Mars Express ion measurements and a 3-D quasi-neutral hybrid model. As Mars Express does not have a …

2002年3月19日 · In this paper the escape of Martian ions is studied with a quasi-neutral hybrid simulation model. The used hybrid model includes two ion species: the solar wind protons and …

We refine a recently presented method to estimate ion escape from non-magnetized planets and apply it to Mars. The method combines in situ observations and a hybrid plasma model (ions …

2010年3月1日 · We have studied the escape and energization of several O + populations and an O 2 + population at Mars by using a hybrid model. The quasi-neutral hybrid model, HYB-Mars …

2008年5月8日 · For Mars' ion escape, we use the solar wind dynamic pressure, derive the residual force term (XEUV) and compare with medium-term effects. On Mars, both solar XEUV …

We here apply a new method for estimating heavy ion (O +, O +2, and CO +2) escape rates at Mars, which combines a hybrid model and observations. We use observed upstream solar …

2019年9月1日 · In a new Mars Express study the ionising nature of the Sun's radiation is found to produce more ions than can be removed by the solar wind. Although the increased ion …
