Abstract: |
Massive stars present the newest and perhaps most challenging opportunity
for long baseline interferometry to excel. Large distances require high
angular resolution both to study the means of accreting enough mass in
a short time and to split new-born multiples into their components for
the determination of their fundamental parameters. Dust obscuration of
young stellar objects requires interferometry in the mid-infrared, while
post-main-sequence stellar phases require high-precision measurements to
challenge stellar evolution models. I will summarize my recent work on
modeling mid-IR observations of a massive YSO in NGC 3603, and on the
derivation of masses and luminosities of a massive hot supergiant star in
another star-forming region in Orion. Challenges presented themselves when
constraining the geometry of a hypothetical accretion disk as well as
obtaining spectroscopy matching the interferometric precision when working
with only a few photospheric lines. As a rapidly evolving application
of interferometry, massive stars have a bright future. |
