cds-question@unistra.freclipsing-binary-starsspectroscopic-binary-starsvariable-starsastronomical-reference-materialsV410 Aur is a known deep and low-mass-ratio contact binary with a spectroscopically tertiary component and a visual companion. However, the physical and orbital properties of the tertiary are unknown. We constructed (O-C) curve with 117 new eclipse times and those collected from the literature, which shows a cyclical variation with a period of 25.44(+/-1.17)yr and a projected semimajor axis of 0.0348(+/-0.0021)d while it undergoes a long-term period decrease at a rate of dP/dt=-1.58x10^-7^d/yr. The cyclical variation is analyzed for the light-travel time effect. The minimum mass of the third body is determined as 1.39(+/-0.13)M_{sun}_ that is much larger than the inferred value (0.97M_{sun}_) of spectroscopic investigation, which indicates that the spectroscopically tertiary is a single-lined spectroscopic binary with an unseen component. The maximum orbital semimajor axis 6.19(+/-0.67)au of the third body is determined. Gaia detected a visual companion to V410 Aur at practically the same distance from the Sun nicely confirming the physical bond. These results reveal that V410 Aur contains a single-lined spectroscopic binary with a visual companion in a quintuple stellar system. TESS photometric solutions confirmed that V410 Aur is a deep overcontact binary with a fill-out factor of 73.83(88)% where the additional light contribution is about 24.80(18)%. The continuous variations of light curves are explained by the evolution of a dark spot on the more massive component. The parabolic variation in the (O-C) curve may be caused by the mass transfer from the massive component to the less massive one in the deep overcontact binary.2022ApJ...927..183Lhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/927/183CatalogResearchIsServedByTAP VizieR generic servicerelated-toII/150 : Parameters of eclipsing binaries (Brancewicz+, 1980)III/218 : ELODIE archive (Prugniel+, 2001)I/311 : Hipparcos, the New Reduction (van Leeuwen, 2007)I/345 : Gaia DR2 (Gaia Collaboration, 2018)IV/39 : TESS Input Catalog version 8.2 (TIC v8.2) (Paegert+, 2021)I/355 : Gaia DR3 Part 1.
