Resumo


Este trabalho apresenta os resultados das observações espectroscópicas de fenda longa realizadas para o par de galáxias peculiares interagentes ESO 505-IG 030 e ESO 505-IG 031. Os dados foram obtidos com o espectrógrafo Cassegrain acoplado ao telescópio Perkin-Elmer (1,60m) do Observatório do Pico dos Dias/Laboratório Nacional de Astrofísica (OPD-LNA/MCTI). Trata-se de um par interagente no Universo local (z $\approx$ 0,03957) classificadas como espirais do tipo morfológico Sc. Curvas de rotação, síntese espectral e alguns parâmetros físicos e geométricos são apresentados e discutidos para cada um dos objetos estudados.

Palavras-chave
