... The large body of near infrared observations presented in Testi et al. (1997; 1998) are analysed with the aim of characterizing the young stellar clusters surrounding Herbig Ae/Be stars. The results confirm the tendency of early Be stars to be surrounded by dense clusters of lower mass "companions", while Ae stars are never found to be associated with conspicuous groups. ... Only the most massive stars (10-20Msun) are found to be associated with dense (10^3 pc^-3) stellar clusters. ...

P22P We explore the structures immediately surrounding the high-mass young stellar object S140 IRS 3 within the L1204 molecular cloud. ... The S-shaped structure of this feature can be well reproduced by a model assuming a precessing outflow from IRS 3a. Furthermore, we find several elongated features pointing away from IRS 3 in a southern direction. ...

We review the evidence, from rotational modulation, for association of plages and spots on active binaries. ... There is a similar lack of evidence for BY Dra systems. The results can be interpreted as evidence for: (a) the presence of active longitudes which persist on some RS CVn stars for several years, (b) high filling factors in MgII emission and (c) lower filling factors, and therefore greater contrast, in SWP emission. ...

The goal is to bring together two communitities: the one working on star formation (mostly galactic) and the one working on the formation of young massive clusters (mostly extra-galactic). We will link galactic with extra-galactic work, optical/NIR techniques with sub-mm/mm/radio ones, the formation of stars with the one of massive star clusters - observations and theory. ...

It is shown that general populations of globular clusters and metal-poor field stars are components at least of three subsystems occupying different volumes in the Galaxy. The thick disk and proto-disk subsystems are genetically associated with the Galaxy. ... It is argued that heavy-element enrichment and the collapse of the proto-galactic medium occurred mainly in the period between the formation of the proto-disk halo and thick disk subsystems. ...

... Transition from strong to weak coupling regime with lowering T c in Tl 2 Ba 2 CuO 6+x. Abstract: . Using 205 Tl NMR, the changes in electronic properties in the normal and superconducting state of the Tl 2 Ba 2 CuO 6+x compound associated with variation of T c , are studied in samples with T c =30, 100, and 115K. Decreasing T c with oxygen doping is shown to be associated with the growth of the static electron spin susceptibility and with lowering the D/ T c ratio ( D is superconducting gap). ...
