An AGB Star with a Thick Circumstellar Shell
  The Asymptotic Giant Branch (AGB) is the terminal phase of red giant
evolution with timescales of millions of years and a total mass lost from the
star that is a significant fraction of the initial mass. Investigation of one
of these stars, WISEA J173046.10-344455.5, a kpc in the direction of the center
of the Galaxy, reveals a cool oxygen rich star with a dust shell of black-body
temperature 1305 K.
