A NUMERICAL ANALYSIS OF THE VARIATION OF THE ORBITAL PERIOD AND THE PHYSICAL MECHANISM OF FLUCTUATION OF THE LIGHT CURVE OF THE CLOSE BINARY VW CEP
【摘要】 <正> Ⅰ. INTRODUCTION The close binary VW Cep is a contact pair of the W-type UMa. Its period is 0.2783 days; spectrum G5+K1; and mass 1.1m_☉+0.4m_☉. Since astronomer Schilt discovered it in 1927, for the past fifty years and more, its luminosity, spectrum and polarization
