Star or something else?

• by Artman40

  I've noticed that this object looks like a star and error bars in SED diagram are small, too. However, it is about as bright in 4.5µm as in 10µm. What can cause that? Contamination?

  It's a Star:

  Type: OSARG - Subtype of LPVs (OSARG=OGLE Small Amplitude Red Giant)

  I don't know if it's contaminated, but Small Magellanic Cloud is "relatively close".
