Red giants are sometimes surrounded by envelopes, the result of the ejection of stellar
matter at a large rate (̇M>10^-7M_⊙/yr) and at a low velocity (10 km/s). In this review the …

Published data for large-amplitude asymptotic giant branch variables in the Large
Magellanic Cloud (LMC) are re-analysed to establish the constants for an infrared (K) period …

This book deals with stars during a short episode before they undergo a ma jor, and fatal,
transition. Soon the star will stop releasing nudear energy, it will become a planetary nebula …

We have performed a cross-identification between Optical Gravitational Lensing Experiment
II (OGLE-II) data and single-epoch Simultaneous three-colour Infrared Imager for Unbiased …

Near-infrared, JHKL, photometry is presented for 193 Mira and semi-regular variables that
were observed by Hipparcos; periods, bolometric magnitudes and amplitudes are derived …

The distance to NGC 5128, the central galaxy of the Centaurus group and the nearest giant
elliptical to us, has been determined using two independent distance indicators: the Mira …

The fifteenth part of the OGLE-III Catalog of Variable Stars (OIII-CVS) contains 232,406 long-
period variables (LPVs) detected in the OGLE-II and OGLE-III fields toward the Galactic …

We report the results of a near-infrared survey for long-period variables in a field of view of
20× 30 arcmin2 towards the Galactic Centre (GC). We have detected 1364 variables, of …

We built K band extinction maps in the area of two candidate low-extinction windows in the
inner Bulge: W0. 2–2.1 at ()=(0.25°,-2.15°), and W359. 4–3.1 at ()=(359.40°,-3.10°). We …

We report periods and JHKL observations for 643 oxygen-rich Mira variables found in two
outer bulge fields at b=− 7° and l=±8° and combine these with data on 8057 inner bulge …
