The Araucaria Project: High-precision orbital parallax and masses of the eclipsing binary TZ Fornacis

Gallenne, A.; Pietrzynski, G.; Graczyk, D.; Konorski, P.; Kervella, Pierre; Merand, A.; Gieren, W.; Anderson, R.; Villanova, S. (EDP SCIENCES, 2016)

Context. Independent distance estimates are particularly useful to check the precision of other distance indicators, while accurate and precise masses are necessary to constrain evolution models. Aims. The goal is to ...

Inspecting the Cepheid parallax of pulsation using Gaia EDR3 parallaxes Projection factor and period-luminosity ...

Trahin, B.; Breuval, L.; Kervella, P.; Merand, A.; Nardetto, N.; Gallenne, Alexandre; Hocde, V.; Gieren, W. (EDP, 2021)

Context. As primary anchors of the distance scale, Cepheid stars play a crucial role in our understanding of the distance scale of the Universe because of their period-luminosity relation. Determining precise and consistent ...
