The Extreme Polarimeter: Design, Performance, First Results & Upgrades
M. Rodenhuis, H. Canovas, S. V. Jeffers +4
Well over 700 exoplanets have been detected to date. Only a handful of these have been observed directly. Direct observation is extremely challenging due to the small separation an…
Evidence for the disintegration of KIC 12557548 b
M. Brogi, C. U. Keller, M. de Juan Ovelar +4
Context. The Kepler object KIC 12557548 b is peculiar. It exhibits transit-like features every 15.7 hours that vary in depth between 0.2% and 1.2%. Rappaport et al. (2012) explain…
Constraining the Circumbinary Envelope of Z CMa via imaging polarimetry
H. Canovas, M. Min, S. V. Jeffers +2
Z CMa is a complex binary system, composed of a Herbig Be and an FU Ori star. The Herbig star is surrounded by a dust cocoon of variable geometry, and the whole system is surrounde…
Direct imaging of a massive dust cloud around R Coronae Borealis
S. V. Jeffers, M. Min, L. B. F. M. Waters +5
We present recent polarimetric images of the highly variable star R CrB using ExPo and archival WFPC2 images from the HST. We observed R CrB during its current dramatic minimum whe…
