Envelope tomography of long-period variable stars III. Line-doubling frequency among Mira stars
R. Alvarez, A. Jorissen, B. Plez +3
This paper presents statistics of the line-doubling phenomenon in a sample of 81 long-period variable (LPV) stars of various periods, spectral types and brightness ranges. When cor…
Envelope tomography of long-period variable stars II. Method
R. Alvarez, A. Jorissen, B. Plez +3
A tomographic method is described that makes it possible to follow the propagation of shock waves across the photosphere of long-period variable stars. The method relies on the cor…
Long Period Variable Stars: galactic populations and infrared luminosity calibrations
M. O. Mennessier, N. Mowlavi, R. Alvarez +1
In this paper HIPPARCOS astrometric and kinematic data are used to calibrate both infrared luminosities and kinematical parameters of Long Period Variable stars (LPVs). Individual…
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…
Period-Luminosity-Colour distribution and classification of Galactic oxygen-rich LPVs
D. Barthes, X. Luri, R. Alvarez +1
The absolute K magnitudes and kinematic parameters of about 350 oxygen-rich Long-Period Variable stars are calibrated, by means of an up-to-date maximum-likelihood method, using Hi…
