dc.description.abstractEnAlthough the Cygnus-X region is primarily known as one of the richest massive star forming regions within 2 kpc, a large number of evolved objects also lie in, or at least along the line-of-sight to, the area observed by the Cygnus-X Spitzer Legacy Survey, including over 100 sources listed by Simbad as carbon stars, Wolf-Rayet stars, planetary nebulae, etc. Our Spitzer 24 micron images, made with the Multi-Band Imaging Photometer for Spitzer (MIPS), reveal previously undetected circumstellar emission from some of these objects. Emission at shorter wavelengths, observed using the Infrared Array Camera (IRAC), was also detected from some of the circumstellar structures, and a few were detected at longer wavelengths (MIPS 70 micron). Here, we present multi-wavelength Spizer images of the objects, including a bipolar nebula around a candidate carbon star BD +43 3710, a shell around the Wolf-Rayet candidate HBHA 4202-22, and a secondary shell around the luminous blue variable G79.29+0.46. In addition to the images, we combine near-infrared data from the 2 Micron All-Sky Survey (2MASS) with our Spitzer data to create spectral energy distributions for both the central objects and surrounding emission. Data from the Infrared Spectrograph (IRS) on Spitzer may also be discussed. We note that spiral structure has also been detected from a radio galaxy in our MIPS 24 micron data.
