The Martian Magnetosphere: Areas of Unsettled Terminology.

The near‐Mars space environment has a number of regions and boundaries that have numerous and confusing labels. The whole region is sometimes referred to as the induced Martian magnetosphere and sometimes as the solar wind interaction with Mars. The middle boundary where the shocked solar wind plasma gives way to predominately planetary‐derived plasma has a variety of names. The region below that middle boundary and the top of the ionosphere also does not have a uniformly used name. There are several other regions and boundaries that also have naming confusion. The various terms that are currently used in the literature for these subjects are identified and discussed; regions and boundaries that have well‐settled names are not discussed nor are the details of the physics involved. Key Points: The near‐Mars plasma environment is often either called (1) the induced Martian magnetosphere or (2) the solar wind interaction with MarsThis interaction has a variety of confusingly overlapping terms for some of its boundaries and regionsTerms that are currently unsettled in the literature for such areas are identified and discussed [ABSTRACT FROM AUTHOR]
