Observation of CO2++ dication in the dayside Martian upper atmosphere
Doubly charged positive ions (dications) are an important component of planetary ionospheres because of the large energy required for their formation.

Variability of Draped Interplanetary Magnetic Field in the Subsolar Martian Ionosphere
In the absence of an intrinsic magnetic field, the solar wind interacts directly with the Martian atmosphere, and the interplanetary magnetic field (IMF) drapes around the ionosphere. With the aid of multi-instrument measurements from Mars Atmosphere and

Martian topography modulated non-migrating tides play important roles in the upper atmosphere and thus in the ionosphere through their coupling, especially in their longitude variations. In this study, the neutral scale height (H n ) and ionospheric peak

Local Generation of Magnetosonic Waves by Ring Beam Hot Protons in the Martian Ionosphere
Magnetosonic (MS) waves are dominant plasma waves causing severe Martian ionospheric erosion. They are generally considered to originate upstream of Martian bow shock with frequencies near the upstream proton gyrofrequency.

Response of photoelectron peaks in the Martian ionosphere to solar EUV/X-ray irradiance
An important population of the dayside Martian ionosphere are photoelectrons that are produced by solar Extreme Ultraviolet and X-ray ionization of atmospheric neutrals.

Variability of the Martian ionosphere from the MAVEN Radio Occultation Science Experiment
The Martian ionosphere is produced by a number of controlling processes, including solar extreme ultraviolet radiation (EUV) and X-ray ionization, impact ionization by precipitating electrons, and day-to-night transport.

Interplanetary Magnetic Field Effect on the Location of the Martian Bow Shock: MAVEN Observations
The Martian bow shock (BS) is generated with the mass-loading and magnetic pileup processes when the solar wind interacts with the Martian ionosphere. In this vein, the interplanetary magnetic field (IMF) frozen in the solar wind can affect the location ...

Martian Proton Aurora Brightening Reveals Atmospheric Ion Loss Intensifying
The Martian proton aurora is a distinct aurora phenomenon resulting from the direct deposition of solar wind energy into Mars' dayside atmosphere. What solar wind parameters influence the aurora activity in the short term is yet unknown, as are the ...
