NASA Exoplanet Archive: Exoplanet Transit Survey HATNet Search

The NASA Exoplanet Archive provides access to high precision time series photometry from stars observed by various transit survey programs. The data have been donated by astronomers who have sought to search for extra-solar planets via photometric transits of the planets around the host stars. The photometric surveys are typically of specific regions of the sky (e.g., field stars, open clusters, etc). Each survey in the archive has different characteristics (e.g., field location, field size, filters in which time-series photometry was performed, magnitude ranges, etc.).

For detailed information about the HATNet dataset, please see the specific holdings page.

We recommend the Firefox, Safari or Chrome browsers.  IE users may see intermittent query failures, which can be resolved by resubmitting the query.

Retrieve Star Light Curve by ID

The star IDs for the HATNet dataset(s) are formatted as a seven digit integer prefixed by 'HAT-' and a 3 digit field number: HAT-field-starid.
Example: HAT-138-0001727
The ID search is case sensitive.
