Query: Mid-IR Observations of T Tauri stars: Probing the Star-Disk Connection
  in Rotational Evolution   We present mid-IR N-band $(\lambda_{eff} = 10.2\micron)$ photometry of a
carefully selected sample of T Tauri stars thought to be single from the
Taurus-Auriga molecular cloud. Infrared excesses in these stars are generally
attributed to circumstellar dust-disks. Combining observations at 2.16$\micron$
(K$_{s}$-band) and 10.2$\micron$ (N-band) we probe a region in the
circumstellar dust-disk from a few stellar radii through the terrestrial planet
zone (0.02-1.0AU). By analyzing the distribution of the $(K_{s}-N)$ color index
with respect to previously measured photometric rotation periods we investigate
what role circumstellar disks play in the rotational evolution of the central
star. The resulting positive correlation between these two variables is
consistent with the notion that a star-disk interaction facilitates the
regulation of angular momentum during the T Tauri stage. We also demonstrate,
how including non-single stars in such an analysis will \textit{weaken} any
correlation in the relation between $(K_{s}-N)$ color and period. To further
understand disk properties we also present SEDs for a few objects with new
ground based M-band $(\lambda_{eff} = 4.8\micron)$ and Q-band $(\lambda_{eff} =
20\micron)$ data and compare them to a geometrically thin, optically-thick disk
model.
