Stellar Age Estimation from ~3 Myr to ~3 Gyr
Lynne Hillenbrand, Eric Mamajek, John Stauffer +3
We present recent progress on quantitative estimation of stellar ages using ind icators such as theoretical evolutionary tracks, rotation, rotation-driven chrom ospheric and corona…
Formation and Evolution of Planetary Systems (FEPS): Properties of Debris Dust around Solar-type Stars
John M. Carpenter, Jeroen Bouwman, Eric E. Mamajek +12
We present Spitzer photometric (IRAC and MIPS) and spectroscopic (IRS low resolution) observations for 314 stars in the Formation and Evolution of Planetary Systems (FEPS) Legacy p…
A Survey for a Coeval, Comoving Group Associated with HD 141569
Alicia N. Aarnio, Alycia J. Weinberger, Keivan G. Stassun +2
We present results of a search for a young stellar moving group associated with the star HD 141569, a nearby, isolated Herbig AeBe primary member of a 5+/-3 Myr-old triple star sys…
Improved Age Estimation for Solar-Type Dwarfs Using Activity-Rotation Diagnostics
Eric E. Mamajek, Lynne A. Hillenbrand
While the strong anti-correlation between chromospheric activity and age has led to the common use of the Ca II H & K emission index (R'_HK = L_HK/L_bol) as an empirical age estima…
The Disk Population of the Chamaeleon I Star-Forming Region
K. L. Luhman, L. E. Allen, P. R. Allen +6
We present a census of circumstellar disks in the Chamaeleon I star-forming region. Using the Infrared Array Camera and the Multiband Imaging Photometer onboard the Spitzer Space T…
