VizieR Online Data Catalog: β Lyr light curves (Mourard+, 2018)

Our study is based on the following sets of dedicated spectrointerferometric observations and multicolor photometric observations.

Three spectro-interferometric instruments took part in a twelve nights long observational campaign aimed at β Lyr in 2013. We also have at our disposal all previous interferometric observations as detailed below.

Navy Precision Optical Interferometer (NPOI) (Armstrong et al., 1998ApJ...496..550A): These observations were carried out in 16 spectral channels spread over wavelength region Δλ=562-861nm with two triplets of telescopes.

Michigan InfraRed Combiner (MIRC) (Monnier et al. 2004, New Frontiers in Stellar Interferometry, ed. W. A. Traub, Vol. 5491, 1370, 2006, in Society of Photo-Optical Instrumentation Engineers (SPIE) Conference Series, Vol. 6268, Society of Photo-Optical Instrumentation Engineers (SPIE) Conference Series, 1): These observations were acquired with six telescopes in H-band split into eight channels. Earlier observations in four-telescope mode have already been analyzed by Zhao et al. (2008ApJ...684L..95Z) and qualitatively compared to a working model. We note also that these observations were acquired before the instrument was equipped with photometric channels (Che et al., 2010, in Proc. SPIE, Vol. 7734, Optical and Infrared Interferometry II, 77342V).

Visible spEctroGraph and polArimeter (VEGA) (Mourard et al. 2009A&A...508.1073M, 2011A&A...531A.110M): These observations were taken in four spectral regions using medium spectral resolution R=5000. In each of these regions two channels in continuum ~10-15nm wide were chosen. Either two or three telescopes were used.
