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…
The Inner Rings of Beta Pictoris
Z. Wahhaj, D. W. Koerner, M. E. Ressler +3
We present Keck images of the dust disk around Beta Pictoris at 17.9 microns that reveal new structure in its morphology. Within 1" (19 AU) of the star, the long axis of the dust e…
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…
Mid-infrared Imaging of a Circumstellar Disk Around HR 4796: Mapping the Debris of Planetary Formation
D. W. Koerner, M. E. Ressler, M. W. Werner +1
We report the discovery of a circumstellar disk around the young A0 star, HR 4796, in thermal infrared imaging carried out at the W.M. Keck Observatory. By fitting a model of the e…
New rotation periods in the Pleiades: Interpreting activity indicators
Anita Krishnamurthi, D. M. Terndrup, M. H. Pinsonneault +13
We present results of photometric monitoring campaigns of G, K and M dwarfs in the Pleiades carried out in 1994, 1995 and 1996. We have determined rotation periods for 18 stars in…
Multiwavelength Observations of a Dramatic High Energy Flare in the Blazar 3C 279
A. E. Wehrle, E. Pian, C. M. Urry +3
The blazar 3C 279, one of the brightest identified extragalactic objects in the gamma-ray sky, underwent a flare of a factor 10 amplitude in gamma-rays towards the end of a 3-week…
