Symbiotic Miras vs. Planetary Nebulae in the Near Infrared
arXiv:astro-ph/0208115
Abstract
While symbiotic Miras and planetary nebulae are hard to distinguish by optical spectroscopy, their near infrared colors differ. We propose the near infrared two-color diagram to be an excellent tool to easily distinguish these two classes of objects.
