AGB Variables as Distance Indicators
Michael Feast
Evidence for the existence of Mira Period-Luminosity relations is reviewed including recent work on Miras with thick circumstellar shells. The calibration of the relation at K is d…
The Case for Asymmetric Dust Around a C-Rich AGB star
Michael W Feast, Patricia A Whitelock, Freddy Marang
JHKL observations of the mass-losing carbon Mira variable IRAS 15194-5115 (II Lup) extending over about 18 years are presented and discussed. The pulsation period is 575 days and h…
Obscured Asymptotic Giant Branch Variables in the Large Magellanic Cloud and the Period-Luminosity Relation
Patricia A. Whitelock, Michael W. Feast, Jacco Th. van Loon +1
The characteristics of oxygen-rich and carbon-rich, large amplitude (dK>0.4 mag), asymptotic giant branch variables in the Large Magellanic Clouds are discussed, with an emphasis o…
Miras and Other Cool Variables with GAIA
Michael Feast
A general review is given of Mira and other cool variable stars, concentrating on those aspects on which GAIA, and more particularly GAIA spectroscopy and radial velocities, will h…
