Experimental rocket R-1A . To mature mass and operating characteristics of rocket R-1, its designers proposed to use an integral fuel tank and a warhead separated from the rocket at the ascent phase completion. In this case, only the ascent phase appeared to be rated for the launch vehicle and considerably more favorable regarding mechanical and thermal loads as compared to the atmospheric portion of the descent phase of the flight trajectory. ...

... A comparison of the positions of the new HSS ELGs in these diagrams shows that our classification appears to be self-consistent for all BCGs, and, therefore, is rather reliable. It is interesting to compare the positions in diagnostic diagram of the new HSS BCGs with those of the well studied BCGs from the SBS sample (Izotov et al. [ 1994 ], [ 1997b ]; Thuan et al. ... Most of the SBS BCGs populate the region with [N II ] ?/ ... We discover two new HSS BCGs located in this region. ...

... 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....
