Remarks
Some references may be clicked to view in new window. Roll over index number to view submission details.
1 Otero, Sebastian Alberto Eclipse time variations show the presence of apsidal motion, which in turn shows the existence of a third body in a relatively close orbit. (2023AJ....166..215O)
2 Jansen, R Highly eccentric system: secondary minimum at phase 0.05048 (amplitude 0.13m). Magnitude from APASS. Amplitude from Kepler data. UCAC4 position.
