We report results of Echelle and B&Ch spectroscopic observations of the emission-line object FBS 0022-021 that were obtained at SPM Observatory, Mexico. We analyze the emission-line spectra along with available optical and IR data. The Fell-rich spectrum of the object closely resembles that of the peculiar binary system η car. The discussion of the physical conditions leading to such spectrum and the nature of this peculiar object are presented.

Resumen

Resumen

Informamos sobre los resultados de observaciones espectroscópicas Echelle y B&C del objeto con líneas de emisión FBS 0022 - 21 obtenidas en el Observatorio de San Pedro Mártir, México. Analizamos los espectros de las líneas de emisión junto con datos del óptico e IR disponibles. El espectro rico en Fell del objeto se asemeja fuertomente al del sistema binario peculiar η Car. Se discuten las condiciones físicas que dan lugar a tal espectro y la naturaleza de este peculiar objeto.
