| 摘要 | The changes in the orbital period of the short-period RS CVn-type binary BH Vir are studied based on the analysis of the O-C curve formed by all photoelectric times of light minimum. It was discovered that the orbital period of BH Vir may show a periodic variation with a period of 9.12 years. A weak evidence also indicating a small amplitude oscillation with a period of 52.7 years in the change of the orbital period. Two possible mechanisms (light times effects due to two hypothetical additional bodies and magnetic activity cycle) that could explained the period behavior are studied. The periodic changes in the orbital period can be explained as due either to magnetic activity cycles in the two components or to the light-times effects of the additional bodies. |
