Detection and Astrometry of the Ba-Bb Subsystem in α Piscium: First Dual-Field Interferometry at the CHARA Array
Dit artikel presenteert de eerste on-sky demonstratie van dual-field interferometrie bij het CHARA Array, waarmee voor het eerst de Ba-Bb sub-systeem in de drievoudige ster α Piscium direct is opgelost en nauwkeurige dynamische massa's zijn bepaald voor deze bijna-tweelingsterren.
