Masers are known to occur in circumstellar envelopes of AGB stars that are long-period variables and have entered the TP-AGB phase. The maser radiation is intrinsically weak and detection limits prevent us from seeing maser stars much beyond the Gala

Red giants are sometimes surrounded by envelopes, the result of the ejection of stellar matter at a large rate ( $\dot M> 10^{-7}M_\odot$ /yr) and at a low velocity (10 km/s). In this review the envelopes are discussed and the relation between stars

In this review I discuss stars in the bulge of our Milky Way, but I exclude stars within a few parsec from Sgr A West; they are the subject of other reviews at this Symposium. We should, however, not forget that there may be an intimate connection be

The INFRARED SPACE OBSERVATORY (ISO), a project of the European Space Agency (ESA), will make various astronomical observations in the wavelength range of 2 to 200 μm. Two-thirds of its observing time will be available to guest observers via the tra

I discuss observable quantities of OH/IR stars and their interpretation. The strong 1612 MHz maser is found in about 1/2 of all the stars that reach the AGB and then have the following properties: they are oxygen–rich, of high–luminosity (3,000

This review concerns stars on the Asymptotic Giant Branch that are about to develop into planetary nebulae (=PNe). They are still termed “stars”, and properly so, and yet they have already, in statu nascendi, the structure of a PN. There are two

These largely historical remarks were meant for those in the audience that had not followed the developments in recent years.One of the great achievements of astrophysics in this century was the discovery of the source of the solar (and stellar) ener

We discuss 766 masers detected in two surveys in the 1612 MHz OH maser line, one made with the Australian Compact Array and the other with the (U.S.) Very Large Array. The surveys covered the sky in l from -45° to +45°, in b from -3° to +3° and o
