Reflected Light from Sand Grains in the Terrestrial Zone of a Protoplanetary Disk
William Herbst, Catrina M. Hamilton, Katherine LeDuc +4
We show that grains have grown to ~mm size (sand sized) or larger in the terrestrial zone (within ~3 AU) of the protoplanetary disk surrounding the 3 Myr old binary star KH 15D. We…
The Orbit and Occultations of KH 15D
Joshua N. Winn, Catrina M. Hamilton, William J. Herbst +4
The unusual flux variations of the pre-main-sequence binary star KH 15D have been attributed to occultations by a circumbinary disk. We test whether or not this theory is compatibl…
The Disappearing Act of KH 15D: Photometric Results from 1995 to 2004
C. M. Hamilton, W. Herbst, F. J. Vrba +14
We present results from the most recent (2002-2004) observing campaigns of the eclipsing system KH 15D, in addition to re-reduced data obtained at Van Vleck Observatory (VVO) betwe…
KH 15D: A Spectroscopic Binary
John A. Johnson, Geoffrey W. Marcy, Catrina M. Hamilton +2
We present the results of a high-resolution spectroscopic monitoring program of the eclipsing pre-main-sequence star KH 15D that reveal it to be a single-line spectroscopic binary.…
Natural Coronagraphic Observations of the Eclipsing T Tauri System KH 15D: Evidence for Accretion and Bipolar Outflow in a WTTS
Catrina M. Hamilton, William Herbst, Reinhard Mundt +2
We present high resolution (R 44,000) UVES spectra of the eclipsing pre-main sequence star KH 15D covering the wavelength range 4780 to 6810 Å obtained at three phases: out…
Fine Structure in the Circumstellar Environment of a Young, Solar-like Star: the Unique Eclipses of KH 15D
William Herbst, Catrina M. Hamilton, Frederick J. Vrba +12
Results of an international campaign to photometrically monitor the unique pre-main sequence eclipsing object KH 15D are reported. An updated ephemeris for the eclipse is derived t…
