Sub-arcsec mid-IR imaging of OH 231.8+4.2
Abstract
We present 0.18$^''$ resolution mid-infrared images of OH231.8+4.2 using the Gemini South telescope. The images show a bright central core of $∼$1$^''$ in size, with extended emissions in the lobes. We find evidence for different chemical composition of the dust in the core and the lobes from the narrow-band images.
