Young Stars in the Time Domain: A Cool Stars 16 Splinter Summary
Kevin R. Covey, Peter Plavchan, Fabienne Bastien +6
Variability is a defining characteristic of young stellar systems, and optical variability has been heavily studied to select and characterize the photospheric properties of young…
A Spitzer IRS Study of Infrared Variability in Transitional and Pre-Transitional Disks around T Tauri Stars
C. Espaillat, E. Furlan, P. D'Alessio +5
We present a Spitzer IRS study of variability in 14 T Tauri stars in the Taurus and Chamaeleon star-forming regions. The sample is composed of transitional and pre-transitional obj…
Spitzer Observations of the Lambda Orionis cluster. II. Disks around solar-type and low mass stars
Jesus Hernandez, Maria Morales-Calderon, Nuria Calvet +5
We present IRAC/MIPS Spitzer Space Telescope observations of the solar type and the low mass stellar population of the young (~5 Myr) Lambda Orionis cluster. Combining optical and…
Modeling the Halpha line emission around classical T Tauri stars using magnetospheric accretion and disk wind models
G. H. R. A. Lima, S. H. P. Alencar, N. Calvet +2
Spectral observations of classical T Tauri stars show a wide range of line profiles, many of which reveal signs of matter inflow and outflow. Halpha is the most commonly observed l…
Modeling Mid-Infrared Variability of Circumstellar Disks with Non-Axisymmetric Structure
Kevin Flaherty, James Muzerolle
Recent mid-infrared observations of young stellar objects have found significant variations possibly indicative of changes in the structure of the circumstellar disk. Previous mode…
The Properties of X-ray Luminous Young Stellar Objects in the NGC 1333 and Serpens Embedded Clusters
E. Winston, S. T. Megeath, S. Wolk +9
We present Chandra X-ray data of the NGC 1333 embedded cluster, combining these data with existing Chandra data, Sptizer photometry and ground based spectroscopy of both the NGC 13…
