Miras Without Masers are Symbiotic Stars
International Astronomical Union Colloquium
AbstractAbout 40% of potential OH / IR stars, color selected from the IRAS Point Source Catalog, have no 1612 MHz masers. While these objects are rarely carbon rich, they are usually associated with circumstellar shells. The natural explanation for these "OH / IR star color mimics" is that they are systems with a degenerate companion collecting an accretion disk from a red giant wind. This provides them with an extra source of UV for dissociating their molecules. The persistent absence of thedoi:10.1017/s0252921100006485 fatcat:3d7vfj4gnvawllppjfhx4efvwy
