... In this poster we propose a hypothesis that within fixed assumptions about internal physics (opacity, thermodynamics, nuclear reactions) a strict relation between the surface helium abundance and the entropy of the adiabatic part of the convective zone exists for all solar models. This hypothesis is verified with models under simplified physics (Christensen­Dalsgaard 1988) and with six evolutionary models computed by Christensen­Dalsgaard (1992). ... 1990, Christensen­Dalsgaard 1991). ...

... Description . ... The SCORPIO-2 project: . ... The multi-mode spectrograph SCORPIO-2 was developed using the experience of observations at the 6-m telescope BTA with the SCORPIO focal reducer . ... The focal reducer consists of several units ('floors') mounted in the common case in the following order (from the telescope focal plane): . ... The focal reducer is connected with the platform-adapter which used for guiding by offset stars and for illumination the spectrograph by calibration lamps. ...
