In this paper, we present the analysis of the stellar system HIP 101227 todetermine the actual number of components in the system, and their properties.We use dynamical modeling and complex spectrophotometric (involving atmosphericmodeling) techniques with recent data, to determine the physical properties andorbital solution for the system, respectively, with better accuracy than paststudies. Based on our analysis, we found that the system is more consistentwith being a quadruple rather than a binary, or a triple system as thatsuggested by previous studies. The total mass of the system determined from ourSED analysis is 3.42 $\pm$ 0.20 $M_{\odot}$, which are distributed almostequally between the four stars. The stars are found to be zero-age mainsequence stars; i.e., at the last stage of pre-main sequence,with age less than200 Myr and spectral types K0. All four stars have very similar physicalcharacteristics, suggesting that fragmentation process is the most likelytheory for the formation and evolution of the system.

The stellar system HIP 101227: is it a binary, a triple or a quadruple system?
