Scientific paper

The spectrum of the carbon star G 77-61 is analyzed by means of model atmospheres. The authors confirm the conjecture - based on astrometric data - that this object is a star near to the main sequence and show that the metal abundances are extremely low, e.g. [Fe/H] = -5.6. The pattern can be understood as the consequence of binary evolution and hypernova processing. The effective temperature is 4200K.
