摘      要：In this paper,we present the analysis of the stellar system HIP 101227 to determine the actual number of components in the system,and their *** use dynamical modeling and complex spectrophotometric(involving atmospheric modeling)techniques with recent data,to determine the physical properties and orbital solution for the system,respectively,with better accuracy than past *** on our analysis,we found that the system is more consistent with being a quadruple rather than a binary or a triple system as suggested by previous *** total mass of the system determined from our SED analysis is 3.42±0.20 M,which is distributed almost equally between the four *** stars are found to be zero-age main sequence stars;i.e.,at the last stage of pre-main sequence,with age less than 200 Myr and spectral types *** four stars have very similar physical characteristics,suggesting that the fragmentation process is the most likely theory for the formation and evolution of the system.
