• W2022250241 abstract "The close binary V337 Aql consists of two early B-type components with an orbital period of 2.7339 d. New multi-band photometric observations of the system together with published radial velocities enabled us to derive the absolute parameters of the components. The simultaneous light and radial velocity curves solution yields masses and radii of emph{M$_{1}$}=17.44$pm$0.31 emph{M$_odot$} and emph{R$_{1}$}=9.86$pm$0.06 emph{R$_odot$} for the primary and emph{M$_{2}$}=7.83$pm$0.18 emph{M$_odot$} and emph{R$_{2}$}=7.48$pm$0.04 emph{R$_odot$} for the secondary component. Derived fundamental parameters allow us to calculate the photometric distance as 1355$pm$160 pc. The present analysis indicates that the system is a near-contact semi-detached binary, in which a primary star is inside its Roche lobe with a filling ratio of 92 percent and the secondary star fills its Roche lobe. From emph{O-C} data analysis, an orbital period decrease was determined with a rate of -7.6 $times$ 10$^{-8}$ yr$^{-1}$. Kinematic analysis reveals that V337 Aql has a circular orbit in the Galaxy and belongs to a young thin-disc population." @default.
