... The star formation rate (SFR) of the current SF episode can be estimated from the total H luminosity. ... For the derived total flux F (H )=5.8 erg s -1 cm -2 we obtain a total H luminosity of 10 39 erg s -1 . ... The total mass of ionized gas can be obtained from the average mass density inside the H II region and its volume. An average mass density corresponding to the average electron density of 1 cm -3 within a volume with a diameter of 0.5 kpc yields a total ionized gas mass of 10 6 . ...

Some astronomers ignore low-mass stars because they aren t very bright. However, stars with initial masses between about 0.8 Msun and 8 Msun (AGB stars) play an important role as the main site of the slow neutron capture (s-)process, which produces roughly half of the elements heavier than iron. ... From this work, we will see have a better understanding of AGB nucleosynthesis, the chemical evolution of globular clusters, and the properties of helium-rich stars. ...

Prague, August 16, 2006 . Another problem that was making it difficult to automatically merge GCVS and survey catalogs has been recently solved: 'old' variable stars also had only very rough coordinates. The GCVS has been identified, on a star-by-star basis, with positional catalogs. ... The total number of stars we were unable to identify, at least tentatively, is only 200, most of them from two or three sources of especially unreliable positional information. ...

... There are several explanations for these X--ray quiet PMS stars. To examine the explanations, it is proper to divide the PMS stars into three groups: those bluer than R - I = 0.7, those redder than the X--ray sources (R - I > 1.25) and those with colors similar to the X--ray sources. ... A total of 26 of the non--X--ray detected PMS candidates had spectra taken. ... Between V=14 and V=16, I find 25 stars which are X--ray sources and estimate 19 non--X--ray PMS stars. ...
