Formation and Evolution of Planetary Systems: Placing Our Solar System in Context with Spitzer
نویسنده
چکیده
We summarize the progress to date of our Legacy Science Program entitled The Formation and Evolution of Planetary Systems (FEPS) based on observations obtained with the Spitzer Space Telescope during its first year of operation. In addition to results obtained from our ground–based preparatory program and our early validation program, we describe new results from a survey for near–infrared excess emission from the youngest stars in our sample as well as a search for cold debris disks around sun–like stars. We discuss the implications of our findings with respect to current understanding of the formation and evolution of our own solar system.

The Formation and Evolution of Planetary Systems: Placing Our Solar System in Context with Spitzer
We provide an overview of the Spitzer Legacy Program “Formation and Evolution of Planetary Systems” (FEPS) which was proposed in 2000, begun in 2001, and executed aboard the Spitzer Space Telescope between 2003 and 2006. This program exploits the sensitivity of Spitzer to carry out mid-infrared spectrophotometric observations of solar-type stars. With a sample of ∼328 stars ranging in age from ...
متن کاملPlanetary Science Goals for the Spitzer Warm Era
The overarching goal of planetary astronomy is to deduce how the present collection of objects found in our Solar System were formed from the original material present in the proto-solar nebula. As over two hundred exo-planetary systems are now known, and multitudes more are expected, the Solar System represents the closest and best system which we can study, and the only one in which we can cl...
متن کاملCircumstellar Disk Evolution: Constraining Theories of Planet Formation
Observations of circumstellar disks around stars as a function of stellar properties such as mass, metallicity, multiplicity, and age, provide constraints on theories concerning the formation and evolution of planetary systems. Utilizing groundand space-based data from the far–UV to the millimeter, astronomers can assess the amount, composition, and location of circumstellar gas and dust as a f...
متن کاملEvolution of Circumstellar Disks Around Normal Stars: Placing Our Solar System in Context
Over the past 10 years abundant evidence has emerged that many (if not all) stars are born with circumstellar disks. Understanding the evolution of post–accretion disks can provide strong constraints on theories of planet formation and evolution. In this review, we focus on developments in understanding: a) the evolution of the gas and dust content of circumstellar disks based on observational ...
متن کاملThe Formation and Evolution of Planetary Systems: First Results from a Spitzer Legacy Science Program
We present 3-160 μm photometry obtained with the IRAC and MIPS instruments for the first five targets from the Spitzer Legacy Science Program “Formation and Evolution of Planetary Systems” and 4-35 μm spectro-photometry obtained with the IRS for two sources. We discuss in detail our observations of the debris disks surrounding HD 105 (G0V, 30 ±10 Myr) and HD 150706 (G3V, ∼ 700 ±300 Myr). For HD...
