Title: Connecting Stellar Properties and Aperiodic Photometric Variability Origins in Young Stars
Abstract:
Although photometric and emission-line variability is a common
property of newly formed stars, the panoply of behavior exhibited by the
periodic as well as the more common aperiodic young star variables has
not yet been assessed in quantitative detail. We are using the Palomar
Transient Factory (PTF) to perform a long duration, high cadence
photometric monitoring survey of the North America and Pelican Nebulae
complex, complementing previous work by us over more than a decade using
both KPNO and other facilities. Here, we propose a spectroscopic
investigation that will 1) improve the membership list for this
relatively poorly-studied star forming region, especially for non-
accreting yet young objects, and 2) provide key information for
understanding the diversity of young star variability and its causes,
thus leading to a more complete understanding of the accretion disk
physics associated with early stellar evolution.
