... Four types of galaxy environments are considered: clusters, centers of groups, other places in groups, and the field. ... In order to check whether the mean ages of the stellar populations depend on environment density monotonically, as the hierarchical par adigm predicts, in this work I consider four types of environment separately: the cluster galaxies, the brightest (central ) galaxies of groups, the secondranked group members, and the field galaxies. ...

But as you may find as we work our way around the stellar тАШcastтАЩ of the Winter Circle, these very bright stars can sometimes be more than just one star, such as Rigel which is actually a triple star system working together to provide such a beautiful twinkle in our night sky. ... Just be careful not to wonder too far away from the circle if trying to star hop around it, there are many diversions and attractions that are out to distract you! ...

R And S5/4.5e. S And SN (NGC 224). W And S7.5/1-e. X And S5/7-e. Z And The light curve is characterized by outbursts up to 4m with intervals of 10 - 20 years. In the intervals cyclic variations are observed with the mean period of 632d and variations with cycles of several days and Delta(m) ~ 0.1m - 0.5m. The spectrum is symbiotic, with features of a late M giant, narrow low-excitation emission lines (Bleq) and forbidden lines characteristic of highly excited nebulae. RR And S6/3.5e.
