Potential Drivers of Mid-Infrared Variability in Young Stars : Testing Physical Models with Multiepoch Near-Infrared Spectra of YSOs in ρ Oph

Abstract

Recent studies have identified several young stellar objects (YSOs) which exhibit significant midinfrared (mid-IR) variability. Awide range of physical mechanisms may be responsible for these variations, including changes in a YSO’s accretion rate or in the extinction or emission from the inner disk. We have obtained and analyzed multiepoch near-infrared… (More)
