Radial Velocity Time Series
We have worked with J. Wright's group at Penn State to include radial velocity time series from the published literature. A wget script for these files is on the Bulk Data Download page in the Time Series Data table. The individual files are also available in the Overview pages for the relevant stars.
Additionally, we offer the RV curves obtained by the MARVELS team described in Thomas et al. 2016. The full data set is in this .tar file; individual RV files are also available in the Overview Pages for the relevant stars.
Data from a study of the completeness of precision radial velocity surveys of nearby stars for planetary companions by Howard & Fulton 2016 are available, including the RV time series, the completeness contour plots and the completeness contour data. The individual files are also available in the Overview pages for the relevant stars.
Amateur Light Curves
The Exoplanet Archive serves 540 light curves for stars currently known to host exoplanets. These light curves of exoplanet transits were obtained by amateur astronomers from around the world and collected by B. Gary of the Amateur Exoplanet Archive. Read the detailed summary of these data and retrieve the files using the retrieval script on the Bulk Data Download page in the Time Series Data table.
Optical Stellar Spectra
Optical stellar spectra are available for both planet and non-planet host stars. There is a retrieval script to download all optical data listed below; as well as scripts to download each data set individually; see the Time Series Data table on the Bulk Data Download page. The data were contributed by the following groups:

Infrared Survey Data
Spitzer Kepler Survey (SpiKeS)
The Spitzer Kepler Survey (SpiKeS) provides high-precision 3.6 and 4.5µm photometry of the ~200,000 stars monitored during the original Kepler survey. Werner et al. 2021 surveyed the entire Kepler field in Cygnus and created a data set to search for low-level infrared excess around Kepler-monitored stars to identify the presence of circumstellar dust and unresolved companions.

Microlensing Planet Light Curves
Microlensing light curves for several confirmed planets have been provided by the authors, including D. Bennett, A. Udalski, Y. Tiannis, C. Han, D. Suzuki and J. Yee. The individual files are available in the Overview pages for the relevant stars. The combined data set retrieval script is on the Bulk Data Download page in the Time Series Data table.

Stellar Abundances
The Exoplanet Archive's System Overview pages contain host star chemical abundances for a set of 10 elements from the Hypatia Catalog. These abundances trace the chemical history and composition of the stars, which can directly impact the formation of planets and the architectures of the resulting planetary systems. To access a specific system overview page, enter the planet or star name in the Explore the Archive search box on the archive's home page.
A good example for viewing Hypatia data is the Kepler-11 System Overview page. The abundances are listed in the Stellar Parameters section, which you expand by clicking on the corresponding plus (+) icon on the right side of the page.

Exozodi Dust Levels
The HOSTS survey for exozodiacal dust concluded that the majority of Sun-like stars have relatively low habitable zone dust levels (Ertel et al. 2020). Indeed, the exozodi luminosity function found to maximize the likelihood of observing the HOSTS data for Sun-like stars has a median exozodi level of 3 zodis. An array of 300,000 exozodi levels randomly drawn from that best-fit luminosity function and expressed in units of solar zodi density can be found below. Questions can be addressed to Bertrand.mennesson(at)jpl.nasa.gov.
