英文摘要We present a comprehensive photometric and spectroscopic analysis of the Algol-type binary Gaia DR3 1892576067672499328. We identified the system as a spectroscopic binary based on medium-resolution LAMOST spectra. Combined with TESS photometry, we determine an orbital period of P = 2.47757(1) * d a low mass ratio of q = 0.098 plus/minus 0.002 and an orbital inclination of i = 46.934(-1.11)(+2.613) deg. The orbit is consistent with being circular (e = 0) The binary comprises a M-1 = 1.817(-0.202)(+0.106) M-circle dot R-1 = 1.265(-0.160)(+0.121) R-circle dot A-type primary and a Roche lobe-filling secondary of M-2 = 0.17910.000 M-circle dot R-2 1.994 +/- 0.0 Ro. The double-peak Ha emission line indicates the possible existence of a Keplerian accretion disc. We established a simple standard accretion disc model and modelled the geometric and dynamical properties of the accretion disc. The obtained outer disc radius R-out approximate to 3.36 +/- 0.43 R-circle dot is consistent with the values inferred from the emission velocity of Ha. Systemic velocity variations observed over time suggest the possible presence of a tertiary companion, with a minimum mass of M3 > 0.369 +/- 0.024 M Given the low mass ratio, the secondary may evolve into a proto-helium white dwarf, forming an El. CVn-type system in the future. This system offers valuable insights into accretion dynamics and the formation of binaries.
