Bill Herbst, the John Monroe Van Vleck Professor of Astronomy, and Seth Redfield, assistant professor astronomy, are co-authors of the article, “Gas Absorption in the KH 15D System: Further Evidence for Dust Settling in the Circumbinary Disk,” published in The Astrophysical Journal, Volume 711, Issue 2, pp. 1297-1305 in March 2010. Their data supports a picture of a particular circumbinary disk as being composed of a very thin particulate grain layer composed of millimeter-sized or larger objects that are settled within whatever remaining gas may be present.

Herbst also is the author of “Periodic variability in the emission spectrum of T Tauri,” published in Astronomy and Astrophysics, Volume 511 in February 2010.
