Distance estimate method for Asymptotic Giant Branch stars using Infrared Spectral Energy Distributions
Rajorshi Bhattacharya, Brandon M. Medina, Ylva M. Pihlström +8
We present a method to estimate distances to Asymptotic Giant Branch (AGB) stars in the Galaxy, using spectral energy distributions (SEDs) in the near- and mid-infrared. By assumin…
