Identifying Primordial Substructure in NGC 2264
Paula S. Teixeira, Charles J. Lada, Erick T. Young +8
We present new Spitzer Space Telescope observations of the young cluster NGC2264. Observations at 24 micron with the Multiband Imaging Photometer has enabled us to identify the mos…
The Disk Fractions of Brown Dwarfs in IC 348 and Chamaeleon I
K. L. Luhman, C. J. Lada, L. Hartmann +7
Using the Infrared Array Camera (IRAC) aboard the Spitzer Space Telescope, we have obtained mid-infrared photometry for 25 and 18 low-mass members of the IC 348 and Chamaeleon I st…
The Formation and Evolution of Planetary Systems (FEPS): Discovery of an Unusual Debris System Associated with HD 12039
D. C. Hines, D. E. Backman, J. Bouwman +17
We report the discovery of a debris system associated with the Myr old G3/5V star HD 12039 using {\it Spitzer Space Telescope} observations from 3.6 -- 160m. An observ…
UBVRI Light Curves of 44 Type Ia Supernovae
Saurabh Jha, Robert P. Kirshner, Peter Challis +2
We present UBVRI photometry of 44 type-Ia supernovae (SN Ia) observed from 1997 to 2001 as part of a continuing monitoring campaign at the Fred Lawrence Whipple Observatory of the…
A Spitzer/IRAC Survey of the Orion Molecular Clouds
S. T. Megeath, K. M. Flaherty, J. Hora +9
We present initial results from a survey of the Orion A and B molecular clouds made with the InfraRed Array Camera (IRAC) onboard the Spitzer Space Telescope. This survey encompass…
Is the Cepheus E Outflow driven by a Class 0 Protostar?
A. Noriega-Crespo, A. Moro-Martin, S. Carey +4
New early release observations of the Cepheus E outflow and its embedded source, obtained with the Spitzer Space Telescope, are presented. We show the driving source is detected in…
Formation and Evolution of Planetary Systems: Cold Outer Disks Associated with Sun-like stars
Jinyoung Serena Kim, Dean C. Hines, Dana E. Backman +24
We present the discovery of debris systems around three solar mass stars based upon observations performed with the Spitzer Space Telescope as part of a Legacy Science Program, ``t…
Reduction Algorithms for the Multiband Imaging Photometer for Spitzer: 6 Months of Flight Data
K. D. Gordon, G. H. Rieke, C. W. Engelbracht +27
The first six months of flight data from the Multiband Imaging Photometer for Spitzer (MIPS) were used to test MIPS reduction algorithms based on extensive preflight laboratory dat…
Reduction Algorithms for the Multiband Imaging Photometer for Spitzer
K. D. Gordon, G. H. Rieke, C. W. Engelbracht +27
We describe the data reduction algorithms for the Multiband Imaging Photometer for Spitzer (MIPS) instrument. These algorithms were based on extensive preflight testing and modelin…
Measuring Accretion in Young Substellar Objects: Approaching the Planetary Mass Regime
J. Muzerolle, K. L. Luhman, C. Briceno +2
We present observations of Halpha emission line profiles taken at Magellan Observatory for a sample of 39 young low-mass stars and brown dwarfs in the Taurus and Chamaeleon I star…
