Evolution of Mid-IR Excess Around Sun-like Stars: Constraints on Models of Terrestrial Planet Formation
M. R. Meyer, J. M. Carpenter, E. E. Mamajek +11
We report observations from the Spitzer Space Telescope (SST) regarding the frequency of 24 micron excess emission toward sun-like stars. Our unbiased sample is comprised of 309 st…
Identification of Main Sequence Stars with Mid-Infrared Excesses Using GLIMPSE: Beta-Pictoris Analogs?
B. Uzpen, H. A. Kobulnicky, K. A. G. Olsen +23
Spitzer IRAC 3.6-8 micron photometry obtained as part of the GLIMPSE survey has revealed mid-infrared excesses for 33 field stars with known spectral types in a 1.2 sq. degree fiel…
A GLIMPSE of Star Formation in the Giant H II Region RCW 49
B. A. Whitney, R. Indebetouw, B. L. Babler +19
GLIMPSE imaging using the Infrared Array Camera (IRAC) on the Spitzer Space Telescope indicates that star formation is ongoing in the RCW 49 giant H II region. A photometric compar…
The Formation and Evolution of Planetary Systems: SIRTF Legacy Science in the VLT Era
M. R. Meyer, D. Backman, S. V. W. Beckwith +20
We will utilize the sensitivity of SIRTF through the Legacy Science Program to carry out spectrophotometric observations of solar-type stars aimed at (1) defining the timescales ov…
Membership, lithium, and metallicity in the young open clusters IC 2602 and IC 2391: enlarging the sample
S. Randich, R. Pallavicini, G. Meola +2
We present lithium abundances for ~50 X-ray selected candidate members of the 30-50 Myr old open clusters IC 2602 and IC 2391. These data enlarge and extend to cooler temperatures…
