... We publish 16 Doppler imaging temperature maps for the years 1994-2002 of the active RS CVn star II Peg. ... Through Doppler imaging we want to study the spot evolution of the star and in particular compare this with previous results showing a cyclic spot behaviour and persistent active longitudes. ... The derived temperature maps are quite similar to the ones obtained earlier with a different methods, the main differences occurring in the spot latitudes and relative strength of the spot structures....

. Authors: A.A. Suchkov , V.A. Marakov . Journal: Pis'ma Astron. Zh., 1976, v.2, p.38-385. Metallisity function of globular clusters in the Galaxy is constructed. It is found to have three "humps". This leads to a conclusion that there were three metal enrichment outbursts during the period of globular cluster formation. The constraints on the nature of metal sourses and on the early evolution of Galaxy are considered.
