The HATSouth Exoplanet Survey

The HATSouth survey has discovered 35 planets as of July 2016. The table below lists these planets, their orbital periods, masses, and radii, and provides links to HATSouth lightcurves from which they were discovered. Click on any table column header to sort by that column. A description of the lightcurve file format is provided at the end of the page.

Lightcurve file schema

The HATSouth lightcurves are provided as gzipped CSV files. There is a small Python module available to read these files (you will need Numpy and PyFITS installed).

Each lightcurve file has a header describing its contents. Here's an example header for the lightcurve file for HATS-4b:

# HAT-553-0015462 - 2MASS J06162689-2232487
# RA = 94.112 deg, DEC = -22.547 deg
# V = 13.36, R = 12.95, I = 12.57, J = 12.03, H = 11.70, K = 11.61
#
# Total LC detections: 33933
# HAT stations: HS01, HS02, HS03, HS04, HS05, HS06

# Filters used:
