  • Authors: Stefan Laos, Keivan G. Stassun, and Robert D. Mathieu

2020 The Astrophysical Journal 902 107.

  • Provider: AAS Journals

Caption: Figure 2.

Top panels: Robo-AO image (left), PSF-subtracted image (middle), and contrast curve (right) of V442 Cyg; residuals reveal distortion in the pre-subtracted image that suggests a tertiary companion to the unresolved SB. Middle panels: Robo-AO image, PSF-subtracted image, and contrast curve of 2MASS J11480818+0138132; residuals clearly do not suggest a tertiary companion. Bottom panels: Robo-AO image, PSF-subtracted image, and contrast curve of V501 Her; residuals indicate an unclear case.
