Abstract
A 1″ resolution map of the [Ne II] 12.8 μm emission from the M supergiant IRS 7 near the Galactic center has revealed a 5″ long ionized «plume» or «tail» of gas leaving the star, in a direction opposite to the radio point source at the Galactic center. While the stellar envelope and tail are likely ionized by the ultraviolet radiation from the Galactic center, ram pressure is more likely to be responsible for the ablation of the supergiant's mass outflow envelope. This ram pressure could arise in one of two sources: a wind from the vicinity of the Galactic center, or the drag caused by the passage of IRS 7 through an ambient medium
