Abstract:
Photometry of the unique pre-main-sequence binary system KH 15D is
presented, spanning the years 2005-2010. This system has exhibited
photometric variations and eclipses over the last ∼50 years that are
attributed to the effect of a precessing circumbinary disk.
Advancement of the occulting edge across the projection on the sky of
the binary orbit has continued and the photospheres of both stars are
now completely obscured at all times. The system has thus transitioned
to a state in which it should be visible only by scattered light, and
yet it continues to show a periodic variation on the orbital cycle
with an amplitude exceeding 2mag.
Description:
In this paper, we report V and I (on the Cousins system) photometric
data on KH 15D obtained at the Van Vleck Observatory (VVO) on the
campus of Wesleyan University in Middletown, CT, at Cerro Tololo
Inter-American Observatory (CTIO) in Chile with a SMARTS consortium
telescope and from Mount Maidanak Observatory (MMO) in Uzbekistan,
operated by the Uzbek Academy of Sciences. Five years of observations
from 2005 September through 2010 March are presented.
