Evaluating the Limits of Rotation Period Recovery through Gyrochronology Criteria
Mariel Lares-Martiz, Terry D. Oswalt, Derek L. Buzasi +3
Contamination from nearby sources often compromises stellar rotation periods derived from photometric light curves, particularly in data with large pixel scales such as TESS. This…

Orbital Characteristics of the Subdwarf-B and F V Star Binary EC~20117-4014(=V4640 Sgr)
T. Otani, T. Oswalt, A. E. Lynas-Gray +4
Among the competing evolution theories for subdwarf-B (sdB) stars is the binary evolution scenario. EC~20117-4014 (=V4640~Sgr) is a spectroscopic binary system consisting of a puls…
