Dynamical Masses and Radiative Transfer Modeling of HD 698: a Be Binary in Evolutionary Transition
Ilfa A. Gabitova, Alex C. Carciofi, Tajan H. de Amorim +13
We present a detailed analysis of the early post-mass-transfer binary HD 698 (V742 Cas) combining high-resolution optical spectroscopy, long-baseline interferometry, and radiative-…

X-Raying a Be star disk: fundamental parameters of the eclipsing binary Be star V658 Car
Tajan H. de Amorim, Alex C. Carciofi, Jonathan Labadie-Bartz +8
With its two stellar eclipses and two disk attenuations per binary orbit, V658 Carinae stands out as the first clear eclipsing Be + sdOB system. This rare alignment offers a unique…

Be star demographics: a comprehensive study of thousands of lightcurves in the Magellanic Clouds
A. L. Figueiredo, A. C. Carciofi, J. Labadie-Bartz +5
Multi-color OGLE survey light curves of about 20 years duration are analyzed for about 3000 classical Be stars in the Large and Small Magellanic Clouds (LMC, SMC) in order to study…
