Although CI Cam, which showed an outburst in April 1998, has been regarded as a soft X-ray transient (SXT) harboring a, black hole, it has some characteristics that can hardly be reconciled with the SXT picture. In this paper, we propose a white dwarf as the central accreting star in CI Cam.

Resumen

Resumen

Aunque CI Cam, la cual presentó una explosión en abril de 1998, ha sido considerada como una fuente transitoria de ray os X suaves (SXT) que alberga un agujero negro, posee a la vez ciertas características que difícilmente pueden hacerla encajar dentro del grupo de SXT. En este artículo proponemos una enana blanca como la estrella central acreciente en CI Cam.
