OH+ in Diffuse Molecular Clouds
My first research experience involved observing near ultraviolet observations of OH and OH+ of over 60 stars using VLT (UVES instrument). We looked at OH+ absorption lines which came from high CH+ to CH density ratio. Similarly, we traced OH absorption present close to CN lines. Our main result shows that OH+ detections may favor low-density gas, whereas OH absorption may appear at high density regions of gas. While OH+ leads to OH production, we argued that the environmental preference of OH and OH+ suggests that the observed OH in high density regions might come from a different formation mechanism. For more information, please refer to my paper publication on this matter. This research was done at the University of Toledo.
