FEPS Photometry Catalog: Circumstellar Dust and Gas Around 328 Solar-Type Stars

The FEPS Spitzer Legacy program catalog contains spectrophotometric observations from the Spitzer Space Telescope for 328 solar-type stars. The data characterize the evolution of circumstellar gas and dust around stars aged between 3 million and 3 billion years. Observations include spectral energy distributions from 3.6 to 70 um via IRAC and MIPS photometry, and low-resolution IRS spectra from 8 to 35 um.

Use Cases

• Modeling the evolution of circumstellar dust disks based on spectral energy distributions.
• Analyzing the correlation between stellar age and infrared excess from the photometric data.
• Classifying stars based on their infrared spectral signatures from the IRS spectra.
• Studying the timeline of planetary system formation around solar-type stars.

Strengths

• Observations for a defined sample of 328 stars.
• Spectral energy distribution data across wavelengths from 3.6 to 70 um.
• Data collected by the Spitzer Space Telescope, a major NASA observatory.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
