Abstract

Presented are the results of a dissertation project. We present the
first interferometric images of cool starspots on the magnetically
active giant lambda Andromeda (Lam And). The 12 images span various
rotational phases in 2010 and 2011, which allow us to directly
characterize the starspot's temperature, location and size. Stellar
rotation can be identified in the 6 images from 2011 that comprise ~40%
of one rotation of Lam And. In a complementary starspot study, we
highlight results of a 3 year near-IR photometric monitoring of young
stars in the rho Ophiuchus star-forming region based on 2MASS
calibration field observations. Of 101 variable stars identified, 32
exhibit periodic variability. For 6 variable stars, two different
physical mechanisms are believed to be operating concurrently. The
variability of 3 of these stars is believed to be caused by periodic
occulations of spotted star, potentially sustained or driven by a
proto-planet or a warped disk, at or near the co-rotation radius.
