Envelope tomography of long-period variable stars: I. The Schwarzschild mechanism and the Balmer emission lines
R. Alvarez, A. Jorissen, B. Plez +2
This paper is the first one in a series devoted to the study of the dynamics of the atmospheres of long-period variable stars. Results from a two-month-long monitoring of the Mira…

Optical and near-infrared spectrophotometric properties of Long Period Variables and other luminous red stars
R. Alvarez, A. Lancon, B. Plez +1
Based on a new and large sample of optical and near-infrared spectra obtained at the Mount Stromlo and Siding Spring Observatories (Lancon & Wood 1998; Lancon & Wood, in preparatio…

Oxygen-rich Mira variables: near-infrared luminosity calibrations. Populations and period-luminosity relations
R. Alvarez, M-O. Mennessier, D. Barthes +2
HIPPARCOS astrometric and kinematical data of oxygen-rich Mira variables are used to calibrate absolute near-infrared magnitudes and kinematic parameters. Two sets of near-infrared…
